springboot中如何利用mybatis-plus配置多数据源

  org.springframework.boot spring-boot-starter   org.apache.httpcomponents httpclient   cn.hutool hutool-all 5.2.0   com.alibaba fastjson 1.2.9   org.projectlombok lombok true    com.baomidou mybatis-plus-boot-starter 3.4.1    com.baomidou dynamic-datasource-spring-boot-starter 3.2.0    mysql mysql-connector-java runtime 

spring: datasource:dynamic: primary: master #指定默认数据库，下面可以配置多个数据库，不仅仅是两个，master就是其中一个数据库的名字，名字对应就可以，自己随便取 datasource:master: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://数据库1ip地址:数据库1端口/数据库1?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=GMT%2B8&allowMultiQueries=true username: 数据库1用户 password: 数据库1密码slave: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://数据库2ip地址:数据库2端口/数据库2?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=GMT%2B8&allowMultiQueries=true username: 数据库2用户 password: 数据库2密码
