才两张表就那么多,是不是感觉,太复杂了!

来种简单的吧.

bee.db.sharding[0].baseTableName=orders
#设置表对应的Class类也可以(要包括包名)
#bee.db.sharding[0].className=org.teasoft.exam.Orders
bee.db.sharding[0].fullNodes=ds[0..1].orders[0..5]
#用于分片的表字段.
bee.db.sharding[0].tabField=orderid

主从表,使用同样的规则,即可在同一库中查询.

对于的Java风格配置:

ShardingConfig.addShardingBean("orders",new ShardingBean("ds[0..1].orders[0..5]", "orderid"));

来后两种就是ORM Bee的,感觉如何.

可下载源码.

ORM Bee, 除了传统ORM功能,还具有 MongoDB ORM, Android ORM, Sharding JDBC 等功能.
