spring:
  datasource:
    yms: #数据源1,亚马逊
      type: com.zaxxer.hikari.HikariDataSource
      driver-class-name: com.mysql.cj.jdbc.Driver # mysql的驱动你可以配置别的关系型数据库
      jdbc-url: jdbc:mysql://cn4lujzijsav.ap-east-1.rds.amazonaws.com:33068/pool_big?useUnicode=true&serverTimezone=Asia/Shanghai&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useAffectedRows=true&allowMultiQueries=true
