Spring MVC+FastJson+Swagger集成的完整实例教程
基础部分
1. FastJson 简介
Fastjson是一个Java库,可用于将Java对象转换为JSON表示。它也可以被用来将一个JSON字符串转换成一个等效的Java对象。在转换速度上应该是最快的,几乎成为了项目的标配(在ajax请求和接口开发时一般都会用fastjson而不再使用jackson)。
GitHub: https://github.com/alibaba/fastjson (本地下载)
特性:
- 在服务器端和android客户端提供最佳性能
- 提供简单toJSONString()和parseObject()方法的Java对象转换为JSON,反之亦然
- 允许存在的无法改变的对象转换为从JSON
- Java泛型的广泛支持
- 允许自定义表示对象
- 支持任意复杂的对象(深继承层次结构和广泛使用泛型类型)
主要特点:
- 快速FAST (比其它任何基于Java的解析器和生成器更快,包括jackson)
- 强大(支持普通JDK类包括任意Java Bean Class、Collection、Map、Date或enum)
- 零依赖(没有依赖其它任何类库除了JDK)
- 支持注解
2. fastjson api
Fastjson API入口类是com.alibaba.fastjson.JSON,常用的序列化操作都可以在JSON类上的静态方法直接完成。
// 把JSON文本parse为JSONObject或者JSONArray public static final Object parse(String text); // 把JSON文本parse成JSONObject public static final JSONObject parseObject(String text); // 把JSON文本parse为JavaBean public static final <T> T parseObject(String text, Class<T> clazz); // 把JSON文本parse成JSONArray public static final JSONArray parseArray(String text); // 把JSON文本parse成JavaBean集合 public static final <T> List<T> parseArray(String text, Class<T> clazz); // 将JavaBean序列化为JSON文本 public static final String toJSONString(Object object); // 将JavaBean序列化为带格式的JSON文本 public static final String toJSONString(Object object, boolean prettyFormat); // 将JavaBean转换为JSONObject或者JSONArray public static final Object toJSON(Object javaObject);
JSONArray:相当于List<Object>
JSONObject:相当于Map<String, Object>
SerializeConfig: 是对序列化过程中一些序列化过程的特殊配置, 如对一些字段进行格式处理(日期、枚举等)
SerializeWriter:相当于StringBuffer
SerializerFeature属性 :
- QuoteFieldNames 输出key时是否使用双引号,默认为true
- UseSingleQuotes 使用单引号而不是双引号,默认为false
- WriteMapNullValue 是否输出值为null的字段,默认为false
- WriteEnumUsingToString Enum输出name()或者original,默认为false
- UseISO8601DateFormat Date使用ISO8601格式输出,默认为false
- WriteNullListAsEmpty List字段如果为null,输出为[],而非null
- WriteNullStringAsEmpty 字符类型字段如果为null,输出为”“,而非null
- WriteNullNumberAsZero 数值字段如果为null,输出为0,而非null
- WriteNullBooleanAsFalse Boolean字段如果为null,输出为false,而非null
- SkipTransientField 如果是true,类中的Get方法对应的Field是transient,序列化时将会被忽略。默认为true
- SortField 按字段名称排序后输出。默认为false
- WriteTabAsSpecial 把\t做转义输出,默认为false 不推荐
- PrettyFormat 结果是否格式化,默认为false
- WriteClassName 序列化时写入类型信息,默认为false。反序列化是需用到
- DisableCircularReferenceDetect 消除对同一对象循环引用的问题,默认为false
- WriteSlashAsSpecial 对斜杠'/'进行转义
- BrowserCompatible 将中文都会序列化为\uXXXX格式,字节数会多一些,但是能兼容IE 6,默认为false
- WriteDateUseDateFormat 全局修改日期格式,默认为false。JSON.DEFFAULT_DATE_FORMAT = “yyyy-MM-dd”;JSON.toJSONString(obj, SerializerFeature.WriteDateUseDateFormat);
- DisableCheckSpecialChar 一个对象的字符串属性中如果有特殊字符如双引号,将会在转成json时带有反斜杠转移符。如果不需要转义,可以使用这个属性。默认为false
- NotWriteRootClassName 含义
- BeanToArray 将对象转为array输出
- WriteNonStringKeyAsString
- NotWriteDefaultValue
- BrowserSecure
- IgnoreNonFieldGetter
- WriteEnumUsingName
实战部分
1、pom.xml 中引入spring mvc、 fastjson 依赖
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.mengdee</groupId> <artifactId>platform-springmvc-webapp</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>platform-springmvc-webapp Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <junit.version>3.8.1</junit.version> <log4j.version>2.5</log4j.version> <jstl.version>1.2</jstl.version> <spring.version>4.2.3.RELEASE</spring.version> <fastjson.version>1.2.32</fastjson.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>${jstl.version}</version> </dependency> <!-- springframework --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>${fastjson.version}</version> </dependency> </dependencies> <!-- 使用aliyun镜像 --> <repositories> <repository> <id>aliyun</id> <name>aliyun</name> <url>http://maven.aliyun.com/nexus/content/groups/public</url> </repository> </repositories> <build> <finalName>platform-springmvc-webapp</finalName> </build> </project>
2、 配置web.xml
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>Archetype Created Web Application</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:conf/spring/spring-*.xml</param-value> </context-param> <listener> <description>Spring监听器</description> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>spring-mvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring-mvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <filter> <filter-name>characterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> <error-page> <error-code>404</error-code> <location>/index.jsp</location> </error-page> </web-app>
3、 配置spring-servlet.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd"> <context:component-scan base-package="com.mengdee.manage.controller" /> <bean id="ViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/"></property> <!-- 视图文件的前缀 --> <property name="suffix" value=".jsp"></property> <!-- 视图文件的后缀名 --> <!-- view是用什么显示,这里是jsp,还可以用velocity之类的 --> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property> </bean> <!-- 启动Spring MVC的注解功能,完成请求和注解POJO的映射 --> <mvc:annotation-driven> <mvc:message-converters register-defaults="true"> <!-- 配置Fastjson 替换原来的jackson支持 --> <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> <value>application/json</value> </list> </property> <property name="features"> <list> <value>QuoteFieldNames</value> <!-- 输出key时是否使用双引号,默认为true --> <value>WriteMapNullValue</value> <!-- 是否输出值为null的字段,默认为false --> <!-- <value>DisableCircularReferenceDetect</value> <value>WriteDateUseDateFormat</value> <value>WriteNullStringAsEmpty</value> 字符类型字段如果为null,输出为"",而非null <value>WriteNullNumberAsZero</value> 数值字段如果为null,输出为0,而非null <value>WriteNullBooleanAsFalse</value> Boolean字段如果为null,输出为false,而非null <value>WriteNullListAsEmpty</value> List字段如果为null,输出为[],而非null --> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> </beans>
4、Java
Education:学历(枚举类)
package com.mengdee.manage.entity; import java.util.HashMap; import java.util.Map; /** * 学历 * @author Administrator * */ public enum Education { KINDERGARTEN("幼儿园", 1), ELEMENTARY("小学", 2), JUNIOR_MIDDLE("初级中学", 3), SENIOR_MIDDLE("高级中学", 4), UNIVERSITY("大学", 5), COLLEGE("学院", 6); private static final Map<Integer, Education> EDUCATION_MAP = new HashMap<Integer, Education>(); static { for (Education education : Education.values()) { EDUCATION_MAP.put(education.getIndex(), education); } } private String text; private int index; private Education(String text, int index) { this.text = text; this.index = index; } public String getText() { return text; } public void setText(String text) { this.text = text; } public int getIndex() { return index; } public void setIndex(int index) { this.index = index; } public static Education getEnum(Integer index) { return EDUCATION_MAP.get(index); } }
Person:
package com.mengdee.manage.entity; import java.util.ArrayList; import java.util.Date; import java.util.List; import java.util.Map; import com.alibaba.fastjson.annotation.JSONField; public class Person { private Long id; private String name; private byte gender; // 性别 1:男 2:女 private short age; // 年龄 private long salary; // 薪水 private double weight; // 体重 private char level; // 评级 private boolean adult; // 是否成年人 private Date birthday; // 生日 private Education education;// 学历 private String[] hobbies; // 爱好 private List<Dog> dogs; // 宠物狗 private Map<String, Object> address; // 住址 // 使用注解控制是否要序列化 @JSONField(serialize = false) private List<Object> obj = new ArrayList<>(); public Person() { } public Person(Long id, String name, byte gender, short age, long salary, double weight, char level, boolean adult, Date birthday, String[] hobbies, List<Dog> dogs, Map<String, Object> address) { super(); this.id = id; this.name = name; this.gender = gender; this.age = age; this.salary = salary; this.weight = weight; this.level = level; this.adult = adult; this.birthday = birthday; this.hobbies = hobbies; this.dogs = dogs; this.address = address; } public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public byte getGender() { return gender; } public void setGender(byte gender) { this.gender = gender; } public short getAge() { return age; } public void setAge(short age) { this.age = age; } public long getSalary() { return salary; } public void setSalary(long salary) { this.salary = salary; } public double getWeight() { return weight; } public void setWeight(double weight) { this.weight = weight; } public char getLevel() { return level; } public void setLevel(char level) { this.level = level; } public boolean isAdult() { return adult; } public void setAdult(boolean adult) { this.adult = adult; } public Date getBirthday() { return birthday; } public void setBirthday(Date birthday) { this.birthday = birthday; } // 处理序列化枚举类型,默认的值是序列化枚举值字符串,而不是枚举绑定的索引或者文本 @JSONField(name = "edu") public int getEdu(){ return education.getIndex(); } @JSONField(name = "edu") public void setEdu(int index){ this.education = Education.getEnum(index); } @JSONField(serialize = false) public Education getEducation() { return education; } @JSONField(serialize = false) public void setEducation(Education education) { this.education = education; } public String[] getHobbies() { return hobbies; } public void setHobbies(String[] hobbies) { this.hobbies = hobbies; } public List<Dog> getDogs() { return dogs; } public void setDogs(List<Dog> dogs) { this.dogs = dogs; } public Map<String, Object> getAddress() { return address; } public void setAddress(Map<String, Object> address) { this.address = address; } }
TestController
package com.mengdee.manage.controller; import java.text.DecimalFormat; import java.util.ArrayList; import java.util.Date; import java.util.HashMap; import java.util.List; import java.util.Map; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import com.alibaba.fastjson.JSON; import com.alibaba.fastjson.JSONArray; import com.alibaba.fastjson.serializer.DoubleSerializer; import com.alibaba.fastjson.serializer.SerializeConfig; import com.alibaba.fastjson.serializer.SimpleDateFormatSerializer; import com.mengdee.manage.entity.Address; import com.mengdee.manage.entity.Dog; import com.mengdee.manage.entity.Education; import com.mengdee.manage.entity.Person; @Controller public class TestController { private static SerializeConfig serializeConfig = new SerializeConfig(); static { serializeConfig.put(Date.class, new SimpleDateFormatSerializer("yyyy-MM-dd HH:mm:ss")); serializeConfig.put(Double.class, new DoubleSerializer(new DecimalFormat("0.00"))); } @RequestMapping("/index") public String index(){ return "index"; } // javabean to object @RequestMapping("/json") @ResponseBody public Object json(){ Person person = new Person(); person.setId(1L); person.setName("mengdee"); person.setAge((short) 18); // /* { "birthday": null, "weight": 0, "dogs": null, "adult": false, "hobbies": null, "education": null, "id": 1, "level": "", "address": null, "age": 18, "name": "mengdee", "gender": 0, "salary": 0 } */ Object personJson = JSON.toJSON(person); return personJson; } // javabean to string @RequestMapping("/json2") @ResponseBody public String json2(){ Person person = new Person(); person.setId(1L); person.setName("mengdee"); person.setAge((short) 18); // 使用该方式值为null的经测试不出来,已经配置了<value>WriteMapNullValue</value> // "{"adult":false,"age":18,"gender":0,"id":1,"level":"","name":"mengdee","salary":0,"weight":0.0}" String jsonString = JSON.toJSONString(person); return jsonString; } @RequestMapping("/json3") @ResponseBody public Object json3(){ Person person = new Person(); person.setId(1L); person.setName("mengdee"); person.setAge((short) 18); person.setBirthday(new Date()); Object personJson = JSON.toJSON(person); // JSON.toJSON(person)默认是毫秒数"birthday":1495073314780, // 使用serializeConfig序列号配置对日期格式化 // "{"birthday":"2017-05-18 10:19:55","weight":0.0,"adult":false,"id":1,"level":"","age":18,"name":"mengdee","gender":0,"salary":0}" String jsonString = JSON.toJSONString(personJson, serializeConfig); return jsonString; } @RequestMapping("/json4") @ResponseBody public Object json4(){ Person person = new Person(); person.setId(1L); person.setName("mengdee"); person.setAge((short) 18); person.setBirthday(new Date()); person.setEducation(Education.UNIVERSITY); // 枚举 String[] hobbies = {"读书", "旅游"}; person.setHobbies(hobbies); Dog dog1 = new Dog(1L, "dog1", (short)1); Dog dog2 = new Dog(2L, "dog2", (short)2); List<Dog> dogs = new ArrayList<>(); dogs.add(dog1); dogs.add(dog2); person.setDogs(dogs); Address address1 = new Address(1l, "上海浦东新区"); Address address2 = new Address(2l, "上海宝山区"); Map<String, Object> addressMap = new HashMap<>(); addressMap.put(address1.getId() + "", address1); addressMap.put(address2.getId() + "", address2); person.setAddress(addressMap); Object personJson = JSON.toJSON(person); return personJson; } @RequestMapping("/json5") @ResponseBody public String json5(){ Dog dog1 = new Dog(1L, "dog1", (short)1); Dog dog2 = new Dog(2L, "dog2", (short)2); List<Dog> dogs = new ArrayList<>(); dogs.add(dog1); dogs.add(dog2); // List<T> -> JSON String jsonString = JSON.toJSONString(dogs, false); System.out.println(jsonString); // JSON -> List<T> List<Dog> parseArray = JSON.parseArray(jsonString, Dog.class); for (Dog dog : parseArray) { System.out.println(dog); } Map<String,Dog> map = new HashMap<String, Dog>(); map.put("dog1",new Dog(1L, "dog1", (short)1)); map.put("dog2",new Dog(2L, "dog2", (short)2)); map.put("dog3",new Dog(3L, "dog3", (short)3)); // Map -> JSON String mapJsonString = JSON.toJSONString(map,true); System.out.println(mapJsonString); // JSON -> Map @SuppressWarnings("unchecked") Map<String,Dog> map1 = (Map<String,Dog>)JSON.parse(mapJsonString); for (String key : map1.keySet()) { System.out.println(key + ":" + map1.get(key)); } // Array -> JSON String[] hobbies = {"a","b","c"}; String hobbiesString = JSON.toJSONString(hobbies,true); System.out.println(hobbies); // JSON -> Array JSONArray jsonArray = JSON.parseArray(hobbiesString); for (Object o : jsonArray) { System.out.println(o); } System.out.println(jsonArray); return jsonString; } }
Swagger集成
第一步:引入相关依赖
<dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.6.1</version> <scope>compile</scope> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.6.6</version> </dependency>
第二步:Swagger信息配置
SwaggerConfig.java
@Configuration @EnableWebMvc @EnableSwagger2 public class SwaggerConfig { @Bean public Docket customDocket() { Docket docket = new Docket(DocumentationType.SWAGGER_2); docket.apiInfo(apiInfo()); docket.select().apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class)); docket.select().paths(PathSelectors.regex("/api/.*")).build(); return docket; } private ApiInfo apiInfo() { Contact contact = new Contact("小明", "http://www.baidu.com", "baidu@163.com"); return new ApiInfo("API接口", //大标题 title "API接口", //小标题 "0.0.1", //版本 "www.baidu.com",//termsOfServiceUrl contact,//作者 "API接口",//链接显示文字 "http://www.baidu.com"//网站链接 ); } }
注意:因SwaggerConfig这个类配置了注解,所以这个类必须被扫描到,即该类一定包含在context:component-scan中。
第三步:在类、方法、参数上使用注解
@Controller @RequestMapping("/api/v1") @Api(description = "API接口") public class ApiController { @ApiOperation(value = "用户登录", notes = "用户登录接口") @ApiResponses({ @ApiResponse(code = 0, message = "success"), @ApiResponse(code = 10001, message = "用户名错误", response = IllegalArgumentException.class), @ApiResponse(code = 10002, message = "密码错误") }) @RequestMapping(value = "/user/login", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8;"}) @ResponseBody public String login(@ApiParam(name = "username", value = "用户名", required = true) @RequestParam String username, @ApiParam(name = "password", value = "密码", required = true) @RequestParam String password){ return "{'username':'" + username + "', 'password':'" + password + "'}"; } @ApiImplicitParams({ @ApiImplicitParam(paramType = "header", name = "phone", dataType = "String", required = true, value = "手机号"), @ApiImplicitParam(paramType = "query", name = "nickname", dataType = "String", required = true, value = "nickname", defaultValue = "双击666"), @ApiImplicitParam(paramType = "path", name = "platform", dataType = "String", required = true, value = "平台", defaultValue = "PC"), @ApiImplicitParam(paramType = "body", name = "password", dataType = "String", required = true, value = "密码") }) @RequestMapping(value = "/{platform}/user/regist", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8;"}) @ResponseBody public String regist(@RequestHeader String phone, @RequestParam String nickname, @PathVariable String platform, @RequestBody String password){ return "{'username':'" + phone + "', 'nickname':'" + nickname + "', 'platform': '" + platform + "', 'password':'"+password+"'}"; } @RequestMapping(value = "/user/list", method = RequestMethod.GET, produces = {"application/json;charset=UTF-8;"}) @ResponseBody public String getUserList(Pager pager){ return "[{'id': "+pager.getPage()+", 'username': 'zhangsan"+pager.getSize()+"'}]"; } @RequestMapping("/docs") @ApiIgnore public String test(){ return "api-docs"; } }
Pager
public class Pager { @ApiModelProperty(value = "页码", required = true) private int page; @ApiModelProperty(value = "每页条数", required = true) private int size; public Pager() { } public int getPage() { return page; } public void setPage(int page) { this.page = page; } public int getSize() { return size; } public void setSize(int size) { this.size = size; } }
常用注解:
- @Api(description = “接口类的描述”)
- @ApiOperation(value = “接口方法的名称”, notes = “备注说明”)
- @ApiParam(name = “参数名称”, value = “备注说明”, required = 是否必须):标注在方法的参数上 用于描述参数的名称、备注、是否必须等信息
- @ApiImplicitParam(paramType = “query”, name = “password”, dataType = “String”, required = true, value = “密码”, defaultValue = “123456”)用于描述方法的参数,标注在方法上,和@ApiParam功能一样,只是标注的位置不同而已
.paramType:参数类型,即参数放在哪个地方
. header–>请求参数的获取:@RequestHeader,参数放在请求头
. query–>请求参数的获取:@RequestParam,参数追加在url后面
. path(用于restful接口)–>请求参数的获取:@PathVariable
. body 使用@RequestBody接收数据 POST有效,参数放在请求体中
. form
.name:参数名
.dataType:参数的数据类型
.required:参数是否必须传
.value:参数的描述
.defaultValue:参数的默认值 - @ApiImplicitParams: 用于包含多个@ApiImplicitParam
- @ApiResponse(code = 0, message = “success”),
.code:响应码,例如400
.message:信息,一般是对code的描述
.response:抛出异常的类 - @ApiModel:描述一个Model的信息(这种一般用在post创建的时候,使用@RequestBody这样的场景,请求参数无法使用@ApiImplicitParam注解进行描述的时候)
.@ApiModelProperty:描述一个model的属性
. position 允许在模型中显式地排序属性。
. value 参数名称
. required 是否必须 boolean
. hidden 是否隐藏 boolean
. allowableValues = “range[0, 1]” 一般用于指定参数的合法值 - @ApiIgnore:用于或略该接口,不生成该接口的文档
第四步:访问/v2/api-docs
在浏览器上访问http://localhost:8080/工程名称/v2/api-docs 如果有json内容,证明正常
第五步:下载swagger-ui
从github上下载https://github.com/swagger-api/swagger-ui,注意这里要选择下载v2.2.10(https://github.com/swagger-api/swagger-ui/tree/v2.2.10 (本地下载)),大于这个版本的集成方式不一样。
集成方法:将v2.2.10下的dist目录下的所有文件放到自己工程中静态文件中,并使用下面代码覆盖掉index.html中的脚本部分
<script type="text/javascript"> var baseUrl = ""; $(function () { var url = window.location.search.match(/url=([^&]+)/); if (url && url.length > 1) { url = decodeURIComponent(url[1]); } else { //上面描述的api-docs地址 url = baseUrl + "/webapp/v2/api-docs"; } // Pre load translate... if (window.SwaggerTranslator) { window.SwaggerTranslator.translate(); } window.swaggerUi = new SwaggerUi({ url: url, validatorUrl: undefined, dom_id: "swagger-ui-container", supportedSubmitMethods: ['get', 'post', 'put', 'delete', 'patch'], onComplete: function (swaggerApi, swaggerUi) { if (typeof initOAuth == "function") { initOAuth({ clientId: "your-client-id", clientSecret: "your-client-secret-if-required", realm: "your-realms", appName: "your-app-name", scopeSeparator: ",", additionalQueryStringParams: {} }); } if (window.SwaggerTranslator) { window.SwaggerTranslator.translate(); } $('pre code').each(function (i, e) { hljs.highlightBlock(e) }); addApiKeyAuthorization(); }, onFailure: function (data) { log("Unable to Load SwaggerUI"); }, docExpansion: "none", jsonEditor: false, apisSorter: "alpha", defaultModelRendering: 'schema', showRequestHeaders: false }); //这里可以添加权限认证,例如token function addApiKeyAuthorization() { var token = "you-token"; var tokenHeader = new SwaggerClient.ApiKeyAuthorization("token", token, "header"); window.swaggerUi.api.clientAuthorizations.add("token", tokenHeader); } window.swaggerUi.load(); function log() { if ('console' in window) { console.log.apply(console, arguments); } } }); </script>
第六步:访问上面修改的那个index.html
http://localhost:8080/工程名称/static/third-party/swagger-ui/index.html
注意:因要访问静态资源,使用springmvc请确保静态资源能够被访问到,如果不能访问请做如下配置:
1、 在Spring的配置文件中增加默认的servlet处理器
<!-- 过滤静态资源 --> <mvc:default-servlet-handler/>
2、 在web.xml中增加要过滤的静态文件
<!-- 过滤静态资源 --> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.js</url-pattern> <url-pattern>*.css</url-pattern> <url-pattern>/assets/*"</url-pattern> <url-pattern>/images/*</url-pattern> </servlet-mapping>

其他
关于spring-servlet.xml 和 applicationContext.xml
SpringMVC 提供了两种配置文件 spring-servlet.xml 、 applicationContext.xml
spring-servlet.xml 是Controller级别的,作用范围是控制层,默认的名字是【servlet-name】-servlet.xml
默认是放在WEB-INF/目录下,SpringMVC会自动加载,也可以在web.xml中配置它的位置
<servlet> <servlet-name>spring-mvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>
一般在spring-servlet.xml中配置一些和控制器相关的配置,如视图解析、静态资源文件的映射、返回结果的解析等
视图解析
- org.springframework.web.servlet.view.UrlBasedViewResolver
- tiles3: org.springframework.web.servlet.view.tiles3.TilesConfigurer
- springMVC: org.springframework.web.servlet.view.InternalResourceViewResolver,
- shiro: org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor
- 上传 org.springframework.web.multipart.commons.CommonsMultipartResolver,
静态资源映射
<mvc:resources location="/static/" mapping="/static/**" /> <mvc:resources location="/images/" mapping="/static/**" /> <mvc:resources location="/css/" mapping="/static/**" /> <mvc:resources location="/js/" mapping="/static/**" /> <mvc:resources location="/html/" mapping="/static/**" /> <mvc:resources location="/upload/" mapping="/static/**" />
org.springframework.context.support.ResourceBundleMessageSource
返回结果的解析
- FastJson: com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter
3、applicationContext.xml 是系统级别的配置,作用范围是系统上下文,它的初始化需要放到 web.xml 中的context-param中配置
<context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:conf/spring/spring-*.xml</param-value> </context-param>
4、 关于applicationContxt.xml,一般是按照功能拆成多个配置文件如:
- - applicationContxt-base.xml // 基础
- - applicationContxt-redis.xml // redis相关配置
- - applicationContxt-shiro.xml // shiro 相关配置
- - applicationContxt-dao.xml // 数据库相关配置
- - applicationContxt-xxx.xml // xxx
