1.maven添加依赖
<?xml version="1.0" encoding="UTF-8"?> <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 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.2.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.hanhuide</groupId> <artifactId>driver</artifactId> <version>0.0.1-SNAPSHOT</version> <name>driver</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus</artifactId> <version>2.3</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.10</version> <scope>compile</scope> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatisplus-spring-boot-starter</artifactId> <version>1.0.5</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>1.1.21</version> </dependency> <dependency> <groupId>p6spy</groupId> <artifactId>p6spy</artifactId> <version>3.8.0</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.9.5</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version>2.2.2.RELEASE</version> <scope>compile</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
2.修改application.yml
server: port: 9000 spring: datasource: type: com.alibaba.druid.pool.DruidDataSource driverClassName: com.p6spy.engine.spy.P6SpyDriver druid: initial-size: 10 max-active: 100 min-idle: 10 max-wait: 60000 pool-prepared-statements: true max-pool-prepared-statement-per-connection-size: 20 time-between-eviction-runs-millis: 60000 min-evictable-idle-time-millis: 300000 validation-query: SELECT 1 FROM DUAL test-while-idle: true test-on-borrow: false test-on-return: false stat-view-servlet: enabled: true url-pattern: /druid/* login-username: admin login-password: admin filter: stat: log-slow-sql: true slow-sql-millis: 1000 merge-sql: true wall: config: multi-statement-allow: true master: #数据源1 url: jdbc:p6spy:mysql://localhost:3306/springcloud?serverTimezone=CTT&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true&useSSL=true username: root password: root cluster: #数据源2 url: jdbc:p6spy:mysql://localhost:3306/occs?serverTimezone=CTT&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true&useSSL=true username: root password: root mybatis-plus: mapper-locations: classpath:/mapper/*.xml type-aliases-package: com.hanhuide.driver.mapper configuration: map-underscore-to-camel-case: true
password: root
3.添加p6spy日志输出配置(spy.properties)与yal同级
module.log=com.p6spy.engine.logging.P6LogFactory,com.p6spy.engine.outage.P6OutageFactory # 自定义日志打印 logMessageFormat=com.p6spy.engine.spy.appender.CustomLineFormat # 使用日志系统记录sql appender=com.p6spy.engine.spy.appender.Slf4JLogger ## 配置记录Log例外 excludecategories=info,debug,result,batc,resultset # 设置使用p6spy driver来做代理 deregisterdrivers=true # 日期格式 dateformat=yyyy-MM-dd HH:mm:ss # 实际驱动 driverlist=com.mysql.cj.jdbc.Driver # 是否开启慢SQL记录 outagedetection=true # 慢SQL记录标准 秒 outagedetectioninterval=2 customLogMessageFormat=%(currentTime) | SQL耗时: %(executionTime) ms | 连接信息: %(category)-%(connectionId) | 执行语句: %(sql)
4.定义数据源名称
package com.hanhuide.driver.dataSource; /** * 数据源名称 * @author 韩惠德 */ public interface DataSourceNames { String MASTER = "MASTER"; String CLUSTER = "CLUSTER"; }
5.配置多数据源,将数据源添加到系统中
package com.hanhuide.driver.config; import com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceBuilder; import com.hanhuide.driver.dataSource.DataSourceNames; import com.hanhuide.driver.dataSource.DynamicDataSource; import lombok.extern.slf4j.Slf4j; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Primary; import javax.sql.DataSource; import java.util.HashMap; import java.util.Map; /** * 配置多数据源 ,将数据源添加到系统中 * * @author 韩惠德 * @date 2018-05-14 */ @Slf4j @Configuration public class DynamicDataSourceConfig { /** * 创建 DataSource Bean */ @Bean @ConfigurationProperties("spring.datasource.master") public DataSource oneDataSource() { DataSource dataSource = DruidDataSourceBuilder.create().build(); return dataSource; } @Bean @ConfigurationProperties("spring.datasource.cluster") public DataSource twoDataSource() { DataSource dataSource = DruidDataSourceBuilder.create().build(); return dataSource; } /** * 如果还有数据源,在这继续添加 DataSource Bean */ @Bean @Primary public DynamicDataSource dataSource(DataSource oneDataSource, DataSource twoDataSource) { Map<Object, Object> targetDataSources = new HashMap<>(); targetDataSources.put(DataSourceNames.MASTER, oneDataSource); targetDataSources.put(DataSourceNames.CLUSTER, twoDataSource); // 还有数据源,在targetDataSources中继续添加 log.info("DataSources:" + targetDataSources); return new DynamicDataSource(oneDataSource, targetDataSources); } }
6.动态数据源
package com.hanhuide.driver.dataSource; import org.springframework.jdbc.datasource.lookup.AbstractRoutingDataSource; import javax.sql.DataSource; import java.util.Map; /** * 动态数据源 * @author 韩惠德 */ public class DynamicDataSource extends AbstractRoutingDataSource { private static final ThreadLocal<String> contextHolder = new ThreadLocal<>(); /** * 配置DataSource, defaultTargetDataSource为主数据库 */ public DynamicDataSource(DataSource defaultTargetDataSource, Map<Object, Object> targetDataSources) { super.setDefaultTargetDataSource(defaultTargetDataSource); super.setTargetDataSources(targetDataSources); super.afterPropertiesSet(); } @Override protected Object determineCurrentLookupKey() { return getDataSource(); } public static void setDataSource(String dataSource) { contextHolder.set(dataSource); } public static String getDataSource() { return contextHolder.get(); } public static void clearDataSource() { contextHolder.remove(); } }
7.配置p6spy输出日志
package com.hanhuide.driver.logger; import com.p6spy.engine.spy.appender.MessageFormattingStrategy; import java.time.LocalDateTime; /** * @program: maven * @description:配置p6spy输出日志 * @author: 韩惠德 * @create: 2019-12-24 15:03 * @version: 1.0 **/ public class P6SpyLogger implements MessageFormattingStrategy { @Override public String formatMessage(int connectionId, String now, long elapsed, String category, String prepared, String sql, String s4) { return !"".equals(sql.trim()) ? "[ " + LocalDateTime.now() + " ] --- | took " + elapsed + "ms | " + category + " | connection " + connectionId + "\n " + sql + ";" : ""; } }
8.利用注解自由切换数据库,自定义注解
package com.hanhuide.driver.annotation; import com.hanhuide.driver.dataSource.DataSourceNames; import java.lang.annotation.*; /** * 多数据源注解 * * @author 韩惠德 * @date 2018-05-14 */ @Documented @Target({ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) public @interface DataSource { String value() default DataSourceNames.MASTER; }
9.利用切面添加注解
package com.hanhuide.driver.aspect; import com.hanhuide.driver.annotation.DataSource; import com.hanhuide.driver.dataSource.DataSourceNames; import com.hanhuide.driver.dataSource.DynamicDataSource; import lombok.extern.slf4j.Slf4j; import org.aspectj.lang.JoinPoint; import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Before; import org.aspectj.lang.annotation.Pointcut; import org.aspectj.lang.reflect.MethodSignature; import org.springframework.core.Ordered; import org.springframework.stereotype.Component; import java.lang.reflect.Method; /** * 数据源AOP切面处理 * * @author geYang * @date 2018-05-14 */ @Slf4j @Aspect @Component public class DataSourceAspect implements Ordered { /** * 切点: 所有配置 DataSource 注解的方法 */ @Pointcut("@annotation(com.hanhuide.driver.annotation.DataSource)") public void dataSourcePointCut() { } @Around("dataSourcePointCut()") public Object around(ProceedingJoinPoint point) throws Throwable { MethodSignature signature = (MethodSignature) point.getSignature(); Method method = signature.getMethod(); DataSource ds = method.getAnnotation(DataSource.class); if (ds == null) { DynamicDataSource.setDataSource(DataSourceNames.MASTER); log.debug("set datasource is " + DataSourceNames.MASTER); } else { DynamicDataSource.setDataSource(ds.value()); log.debug("set datasource is " + ds.value()); } try { return point.proceed(); } finally { DynamicDataSource.clearDataSource(); log.debug("clean datasource"); } } @Override public int getOrder() { return 1; } }
8.配置启动类
到此springboot配置druid多数据源 ,注解切换的代码就完事了
接下来我们编辑测试类
1.随便一个实体类
package com.hanhuide.driver.Service; import com.baomidou.mybatisplus.annotations.TableField; import com.baomidou.mybatisplus.annotations.TableId; import com.baomidou.mybatisplus.annotations.TableName; import com.baomidou.mybatisplus.enums.IdType; import lombok.Data; import java.io.Serializable; import java.util.Date; import java.util.List; /** * <p> * * </p> * * @author 韩惠德 * @since 2019-11-29 */ @TableName("sys_user") @Data public class SysUser implements Serializable{ private static final long serialVersionUID = 1L; /** * 用户ID */ @TableId(value = "USER_ID", type = IdType.AUTO) private Long userId; /** * 用户名 */ @TableField("USERNAME") private String username; /** * 密码 */ @TableField("PASSWORD") private String password; /** * 部门ID */ @TableField("DEPT_ID") private Long deptId; /** * 邮箱 */ @TableField("EMAIL") private String email; /** * 联系电话 */ @TableField("MOBILE") private String mobile; /** * 状态 0锁定 1有效 */ @TableField("STATUS") private String status; /** * 创建时间 */ @TableField("CREATE_TIME") private Date createTime; /** * 修改时间 */ @TableField("MODIFY_TIME") private Date modifyTime; /** * 最近访问时间 */ @TableField("LAST_LOGIN_TIME") private Date lastLoginTime; /** * 性别 0男 1女 2保密 */ @TableField("SSEX") private String ssex; /** * 描述 */ @TableField("DESCRIPTION") private String description; /** * 用户头像 */ @TableField("AVATAR") private String avatar; public void setAvatar(String avatar) { this.avatar = avatar; } public static final String USER_ID = "USER_ID"; public static final String USERNAME = "USERNAME"; public static final String PASSWORD = "PASSWORD"; public static final String DEPT_ID = "DEPT_ID"; public static final String EMAIL = "EMAIL"; public static final String MOBILE = "MOBILE"; public static final String STATUS = "STATUS"; public static final String CREATE_TIME = "CREATE_TIME"; public static final String MODIFY_TIME = "MODIFY_TIME"; public static final String LAST_LOGIN_TIME = "LAST_LOGIN_TIME"; public static final String SSEX = "SSEX"; public static final String DESCRIPTION = "DESCRIPTION"; public static final String AVATAR = "AVATAR"; @Override public String toString() { return "SysUser{" + "userId=" + userId + ", username=" + username + ", password=" + password + ", deptId=" + deptId + ", email=" + email + ", mobile=" + mobile + ", status=" + status + ", createTime=" + createTime + ", modifyTime=" + modifyTime + ", lastLoginTime=" + lastLoginTime + ", ssex=" + ssex + ", description=" + description + ", avatar=" + avatar + "}"; } }
2.编写mapper
package com.hanhuide.driver.Service; import com.baomidou.mybatisplus.mapper.BaseMapper; import com.hanhuide.driver.annotation.DataSource; import com.hanhuide.driver.dataSource.DataSourceNames; import org.apache.ibatis.annotations.Select; import org.springframework.stereotype.Service; import java.util.List; /** * @program: maven * @description: * @author: 韩惠德 * @create: 2019-12-24 16:39 * @version: 1.0 **/ @Service public interface CeshiMapper extends BaseMapper<SysUser> { @Select("select * from sys_user") List<SysUser> findAll(); @Select("select * from sys_user") @DataSource(DataSourceNames.CLUSTER)//注解切换数据源 List<SysUser> findAll2(); }
再写个contrller
package com.hanhuide.driver.Service; import lombok.extern.slf4j.Slf4j; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; import javax.annotation.Resource; import java.util.List; /** * @program: maven * @description: * @author: 韩惠德 * @create: 2019-12-24 16:41 * @version: 1.0 **/ @RestController @Slf4j public class Contrller11 { @Resource private CeshiMapper ceshiMapper; @GetMapping("ceshi") public List<SysUser> ceshi() { return ceshiMapper.findAll(); } @GetMapping("ceshi2") public List<SysUser> ceshi2() { return ceshiMapper.findAll2(); } }
到此测试类类及方法就完成了,启动运行
两个数据源已经连接
项目已启动
连接主数据库成功
p6spy 搭建成功 但是乱码没有解决
说明数据库切换成功
打开druid的监控页面查看当前数据源的相关信息,登录用户名密码在配置文件共配置了
查看两个数据源
总结
以上为个人经验,希望能给大家一个参考,也希望大家多多支持脚本之家。
