如何在Java SpringBoot项目中配置动态数据源你知道吗

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>dynamic-datasource-spring-boot-starter</artifactId>
    <version>3.3.5</version>
</dependency>

spring:
  datasource:
    dynamic:
      primary: master #设置默认的数据源或者数据源组,默认值即为master
      strict: false #严格匹配数据源,默认false. true未匹配到指定数据源时抛异常,false使用默认数据源
      datasource:
        master: # 名称可以自己定义
          url: jdbc:mysql://localhost:3306/students?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=GMT%2B8
          username: root
          password: root
          driver-class-name: com.mysql.cj.jdbc.Driver
        slave: # 名称可以自己定义
          url: jdbc:mysql://localhost:3306/teachers?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=GMT%2B8
          username: root
          password: root
          driver-class-name: com.mysql.cj.jdbc.Driver
