SpringBoot+Vue+Axios+BootStrap实现图书的增删改查功能示例
由于是初学Vue、Axios,可能在界面和功能上存在着一些问题,但这些并不妨碍使用。如果有对编程感兴趣的朋友,可以试着做一做。这个由于是第一次做,不太熟练。在后续的过程中会不断的完善。
一、开发工具
IntelliJ IDEA Ultimate 2021.1
apache-maven-3.5.4
MySQL5.7
JDK 1.8.0_281
二、项目结构
三、编写项目
1、创建数据库
SET NAMES utf8mb4; SET FOREIGN_KEY_CHECKS = 0; -- ---------------------------- -- Table structure for books -- ---------------------------- DROP TABLE IF EXISTS `books`; CREATE TABLE `books` ( `bookId` int(0) NOT NULL AUTO_INCREMENT COMMENT '书id', `bookName` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '书名', `bookCounts` int(0) NOT NULL COMMENT '数量', `detail` varchar(200) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '描述', PRIMARY KEY (`bookId`) USING BTREE, INDEX `bookID`(`bookId`) USING BTREE ) ENGINE = InnoDB AUTO_INCREMENT = 4 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic; -- ---------------------------- -- Records of books -- ---------------------------- INSERT INTO `books` VALUES (1, 'Java', 1, '从入门到放弃'); INSERT INTO `books` VALUES (2, 'MySQL', 10, '从删库到跑路'); INSERT INTO `books` VALUES (3, 'Linux', 5, '从进门到进牢'); SET FOREIGN_KEY_CHECKS = 1;
2、添加依赖
<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.2.0</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.webjars</groupId> <artifactId>bootstrap</artifactId> <version>3.4.1</version> </dependency> <dependency> <groupId>org.webjars.bower</groupId> <artifactId>jquery</artifactId> <version>3.6.0</version> </dependency> <dependency> <groupId>org.webjars.npm</groupId> <artifactId>vue</artifactId> <version>2.6.14</version> </dependency> <dependency> <groupId>org.webjars.npm</groupId> <artifactId>axios</artifactId> <version>0.20.0</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.78</version> </dependency> </dependencies>
3、修改项目resources目录下application.properties
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver spring.datasource.url=jdbc:mysql://localhost:3306/ssmbuild?useUnicode=true&characterEncoding=utf8 spring.datasource.username=root spring.datasource.password=123456 mybatis.mapper-locations=classpath:mapper/*.xml mybatis.type-aliases-package=com.example.pojo
4、在pojo包中编写实体类
package com.example.pojo; import lombok.AllArgsConstructor; import lombok.Data; import lombok.NoArgsConstructor; @Data @AllArgsConstructor @NoArgsConstructor public class Book { private Integer bookId; private String bookName; private Integer bookCounts; private String detail; }
5、在java目录下的mapper包中编写接口类
package com.example.mapper; import com.example.pojo.Book; import org.springframework.stereotype.Repository; import java.util.List; @Repository public interface BookMapper { List<Book> findAll(); int addBook(Book book); int updateBook(Book book); int deleteBook(Integer bookId); }
6、在resources目录下的mapper中编写mapper.xml文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.example.mapper.BookMapper"> <resultMap id="bookMap" type="com.example.pojo.Book"> <id column="bookId" property="bookId" javaType="Integer"/> <result column="bookName" property="bookName" javaType="String"/> <result column="bookCounts" property="bookCounts" javaType="Integer"/> <result column="detail" property="detail" javaType="String"/> </resultMap> <select id="findAll" resultMap="bookMap"> select * from books </select> <insert id="addBook" parameterType="com.example.pojo.Book"> insert into books (bookName, bookCounts, detail) values (#{bookName}, #{bookCounts}, #{detail}); </insert> <update id="updateBook" parameterType="com.example.pojo.Book"> update books set bookName=#{bookName}, bookCounts=#{bookCounts}, detail=#{detail} where bookId = #{bookId} </update> <delete id="deleteBook" parameterType="Integer"> delete from books where bookId = #{bookId} </delete> </mapper>
7、在service包中编写接口
package com.example.service; import com.example.pojo.Book; import com.example.vo.ResultVO; import java.util.List; public interface BookService { List<Book> findAll(); ResultVO addBook(Book book); ResultVO updateBook(Book book); int deleteBook(Integer bookId); }
8、在service包下的impl包中编写接口的实现类
package com.example.service.impl; import com.example.mapper.BookMapper; import com.example.pojo.Book; import com.example.service.BookService; import com.example.vo.ResultVO; import org.springframework.stereotype.Service; import javax.annotation.Resource; import java.util.List; @Service public class BookServiceImpl implements BookService { @Resource private BookMapper bookMapper; @Override public List<Book> findAll() { return bookMapper.findAll(); } @Override public ResultVO addBook(Book book) { int i = bookMapper.addBook(book); if (i==1){ return new ResultVO(10000,"success"); }else { return new ResultVO(10001,"defeat"); } } @Override public ResultVO updateBook(Book book) { int i = bookMapper.updateBook(book); if (i==1){ return new ResultVO(10000,"success"); }else { return new ResultVO(10001,"defeat"); } } @Override public int deleteBook(Integer bookId) { return bookMapper.deleteBook(bookId); } }
9、在controller包中编写控制层实现的方法
package com.example.controller; import com.example.pojo.Book; import com.example.service.BookService; import com.example.vo.ResultVO; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.*; import javax.annotation.Resource; import java.util.List; @Controller public class BookController { @Resource private BookService bookService; @RequestMapping("/bookAll") @ResponseBody public List<Book> bookAll(){ List<Book> bookList = bookService.findAll(); return bookList; } @PostMapping("/bookAdd") @ResponseBody public ResultVO addBook(@RequestBody Book book){ ResultVO resultVO = bookService.addBook(book); return resultVO; } @PostMapping("/bookUpdate") @ResponseBody public ResultVO updateBook(@RequestBody Book book){ return bookService.updateBook(book); } @GetMapping("/bookDelete/{bookId}") @ResponseBody public int deleteBook(@PathVariable("bookId") Integer bookId){ return bookService.deleteBook(bookId); } }
10、在vo包中编写ResultVo
package com.example.vo; import lombok.AllArgsConstructor; import lombok.Data; import lombok.NoArgsConstructor; @Data @NoArgsConstructor @AllArgsConstructor public class ResultVO { //响应码 private int code; //提示消息 private String msg; //响应数据 private Object data; public ResultVO(int code,String msg){ this.code=code; this.msg=msg; } }
11、在webapp下创建list.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>书籍列表</title> <!--1. 添加vue依赖--> <script src="/webjars/vue/2.6.14/dist/vue.min.js"></script> <!--2. 添加axios依赖--> <script src="/webjars/axios/0.20.0/dist/axios.min.js"></script> <!--3. 添加jquery依赖--> <script src="/webjars/jquery/3.6.0/dist/jquery.min.js"></script> <!--4. 添加bootstrap依赖--> <link rel="stylesheet" href="/webjars/bootstrap/3.4.1/css/bootstrap.min.css"> <script src="/webjars/bootstrap/3.4.1/js/bootstrap.min.js"></script> <style> .table { text-align: center; } </style> </head> <body> <div class="container"> <div class="panel panel-primary"> <div class="panel-heading"> <div class="panel-title"> <h3>书籍列表(SpringBoot+ Vue + Axios + BootStrap)</h3> </div> </div> <table class="table table-striped table-hover"> <tr> <td>书籍编号</td> <td>书籍名称</td> <td>书籍数量</td> <td>书籍描述</td> <td>操作</td> </tr> <tr v-for="bk in bookList"> <td>{{bk.bookId}}</td> <td>{{bk.bookName}}</td> <td>{{bk.bookCounts}}</td> <td>{{bk.detail}}</td> <td> <a href="#" class="btn btn-success btn-sm" data-toggle="modal" data-target="#myModal" @click="book=bk;title='修改书籍'">修改</a> <a href="" class="btn btn-danger btn-sm" @click="delBook(bk.bookId)">删除</a> </td> </tr> </table> <div class="panel-footer text-right"> <a href="#" class="btn btn-info btn-sm" data-toggle="modal" data-target="#myModal" @click="book={};title='添加书籍'">添加书籍</a> </div> <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h4 class="modal-title">{{title}}</h4> --{{book}} </div> <div class="modal-body"> <form class="form-horizontal" method="post"> <input type="hidden" v-model="book.bookId"> <div class="form-group"> <label class="col-sm-2 control-label">书籍名称:</label> <div class="col-sm-10"> <input type="text" class="form-control" v-model="book.bookName" placeholder="书籍名称"> </div> </div> <div class="form-group"> <label class="col-sm-2 control-label">书籍数量:</label> <div class="col-sm-10"> <input type="text" class="form-control" v-model="book.bookCounts" placeholder="书籍数量"> </div> </div> <div class="form-group"> <label class="col-sm-2 control-label">书籍描述:</label> <div class="col-sm-10"> <input type="text" class="form-control" v-model="book.detail" placeholder="书籍描述"> </div> </div> </form> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">关闭(C)</button> <button type="button" class="btn btn-primary" @click="save()">保存(S)</button> </div> </div> </div> </div> </div> </div> </body> </html> <script> let vs = new Vue({ el: '.container', data: { bookList: [], book: {}, title: '添加书籍', }, created() { //查询所有图书信息 this.findAllBooks(); }, methods: { //1、查询全部图书信息 findAllBooks() { axios.get("/bookAll").then(data => { this.bookList = data.data }) }, //2、保存图书 save() { //根据bkl.bookId是否有值,决定添加还是修改 let url = "/bookAdd"; if (this.book.bookId) { url = "/bookUpdate"; } //向后台发送请求 axios({ method:'post', url:url, data:JSON.stringify(this.book), headers:{ 'Content-type':'application/json' } }).then(res=>{ if (res.data.code==10000){ this.findAllBooks(); } $("#myModal").modal('hide'); }) }, //3、删除书籍 delBook(bookId) { let url = "/bookDelete/"+bookId; if (confirm("你确定要删除吗?")) { axios.get(url).then(function (res){ if (res.data.code===10000){ this.findAllBooks(); } }) } } } }) </script>
