1、需要的依赖，版本自行控制

<dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId>
</dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId>
</dependency><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId>
</dependency><dependency><groupId>com.baomidou</groupId><artifactId>dynamic-datasource-spring-boot-starter</artifactId>
</dependency>

2、配置文件

spring:datasource:dynamic:primary: masterstrict: falsedatasource:master:url: jdbc:mysql://xxx?useSSL=false&useUnicode=true&characterEncoding=utf8username: rootpassword: pasdriver-class-name: com.mysql.cj.jdbc.Drivertwo:url: jdbc:mysql://xxx?useSSL=false&useUnicode=true&characterEncoding=utf8username: rootpassword: pasdriver-class-name: com.mysql.cj.jdbc.Driver

3、使用方法，添加DS注解，值为配置的数据源名称

4、直接使用
