Springboot2.x + sharding-jdbc + 分库(不分表)

数据源不能使用下划线 “_”  如 

member0 不能写为 member_0 ,否刚会报错

sharding-jdbc 配置 ，不需要java配置

# 数据源
sharding:
  jdbc:
    config:
      sharding:
        default-data-source-name: member1
        default-database-strategy:
          inline:
            sharding-column: business_id
            algorithm-expression: member${business_id}


    datasource:
      names: member0,member1
    #商家0的DB
      member0:
        type: com.alibaba.druid.pool.DruidDataSource
        url: jdbc:mysql://mysql1:3306/ybf_member0?useUnicode=true&characterEncoding=utf8&useSSL=true&allowMultiQueries=true&verifyServerCertificate=false
        username: root
        password: 123456
      member1:
        type: com.alibaba.druid.pool.DruidDataSource
        url: jdbc:mysql://mysql1:3306/ybf_member1?useUnicode=true&characterEncoding=utf8&useSSL=true&allowMultiQueries=true&verifyServerCertificate=false
        username: root
        password: 123456
