shardingsphere 读写分离之主从配置

[littlecold]

版本是 5.1.1 ，主从数据库，分表不分库，表 sharding 没啥问题，主从的读写分离就一直不行，请求各位大佬支援。

spring:
  shardingsphere:
    datasource:
      names: ds0,ds1
      # 主库 1,master 数据库
      ds0:
       xxxxxx
      # 从库 1,slave 数据库
      ds1:
        xxxxx
    props:
      sql-show: true
      sql-simple: false
      # 是否在启动时检查分表元数据一致性
      check-table-metadata-enabled: true
      check-duplicate-table-enabled: false
      sql-comment-parse-enabled: false
      sql-federation-enabled: false
    rules:
      # 分片
      sharding:
        tables:
          xxxxxx:
            actual-data-nodes: ds$->{0..1}.xxxxx$->{0..7}
            table-strategy:
              standard:
                sharding-column: uid
                sharding-algorithm-name: xxxxAl
        default-sharding-column: uid
        binding-tables:
          - xxxxxx
        broadcast-tables:
        default-database-strategy:
          none:
        default-table-strategy:
          none:


        sharding-algorithms:
          xxxxAl:
            type: INLINE
            props:
              algorithm-expression: xxxxxx_xxxx
      ### 读写分离
      readwrite-splitting:
        data-sources:
          readwrite_ds:
            type: Static
            load-balancer-name: round_robin
            props:
              write-data-source-name: ds0
              read-data-source-names: ds1
        load-balancers:
          round_robin:
            type: ROUND_ROBIN
