ShardingJdbc:集成ShardingSphere后，像MasterDataTable這樣不需要分庫分表，該怎么實現的一個方案

如題

采用了shardingSphere后，分庫策略，分表策略都可以靈活使用了。

反過來會遇到一個新的問題，比如有個表不需要分庫，也不需要分表，那么該怎么處理呢？

這里就要ShardingStrategy中的none配置了。

下面把配置貼出來：見配置中紅色字體。

關鍵點：

   default-data-source-name設置為主庫數據源

  actual-nodes:設置主庫數據源和物理表名

  database-strategy:設置none

  table-strategy:設置none
