    druid:
      #特别提示:配置数据库加密 config这个不能忘掉
      filters: stat,wall,config
      use-global-data-source-stat: true
      # 开启解密config.decrypt=true; 公钥:config.decrypt.key
      connect-properties:
        druid.stat.mergeSql: true
        druid.stat.slowSqlMillis: 5000
        druid.stat.logSlowSql: true
        config.decrypt: true
        config.decrypt.key: 公钥
      # 连接池的配置信息
      # 初始化大小，最小空闲连接数，最大活跃数
      initial-size: 5
      min-idle: 5
      maxActive: 20
      # 配置获取连接等待超时的时间
      maxWait: 60000
      # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
      timeBetweenEvictionRunsMillis: 60000
      # 配置一个连接在池中最小生存的时间，单位是毫秒
      minEvictableIdleTimeMillis: 300000
      validationQuery: SELECT 1 FROM DUAL
      testWhileIdle: true
      testOnBorrow: false
      testOnReturn: false
      # 打开PSCache，并且指定每个连接上PSCache的大小
      poolPreparedStatements: true
      maxPoolPreparedStatementPerConnectionSize: 20

Four: Multiple data sources

Add dependencies

<dependency>
    <groupId>com.alibaba</groupId>
