This is a demo of sharding database and table using sharding jdbc

1. 创建两个数据库 ds_0 和 ds_1
2. 每个库分表创建两个表t_order_0和t_order_1,sql语句如下：
   DROP TABLE IF EXISTS t_order_0; CREATE TABLE t_order_0 ( order_id bigint(20) NOT NULL, user_id bigint(20) NOT NULL, PRIMARY KEY (order_id) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin;
3. 下载代码，修改DateSourceConfig类里的username，password即可启动
