多数据源实现-基于mybaties-plus

前言，这里是参考mybaties plus官方实现，效果很不错，下面是实现大概过程：

1、引入依赖：

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>dynamic-datasource-spring-boot-starter</artifactId>
    <version>3.4.0</version>
</dependency>

2、配置yml文件:

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:
          url: jdbc:mysql://localhost:3306/gcp_esource?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=GMT%2B8&allowMultiQueries=true&allowPublicKeyRetrieval=true
          username: gcp_esource
          password: '@Gcp_esource2021'
          driver-class-name: com.mysql.cj.jdbc.Driver
          type: com.alibaba.druid.pool.DruidDataSource
          druid:
            filters: stat
            max-active: 20
            initial-size: 1
            max-wait: 60000
            min-idle: 10
            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: true
            test-on-return: true
            pool-prepared-statements: true
            max-open-prepared-statements: 20
        gcpdw:
          url: jdbc:mysql://localhost:3306/gcp_dw?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=GMT%2B8&allowMultiQueries=true&allowPublicKeyRetrieval=true

          type: com.alibaba.druid.pool.DruidDataSource
          driver-class-name: com.mysql.cj.jdbc.Driver
          druid:
            filters: stat
            max-active: 20
            initial-size: 1
            max-wait: 60000
            min-idle: 10
            time-between-eviction-runs-millis: 60000
            min-evictable-idle-time-millis: 300000
            validation-query: SELECT 1
            test-while-idle: true
            test-on-borrow: true
            test-on-return: true
            pool-prepared-statements: true
            max-open-prepared-statements: 20
