2.异常分析

1.首先是由于我们的表是分表了：一张t_order 表分成了20张表即为：t_order_00,
t_order_01,
t_order_02,
t_order_03,
t_order_04,
t_order_05,
t_order_06,
t_order_07,
t_order_08,
t_order_09,
t_order_10,
t_order_11,
t_order_12,
t_order_13,
t_order_14,
t_order_15,
t_order_16,
t_order_17,
t_order_18,
t_order_19

由于进入分表策略的时候逻辑表匹配不到物理真实的表(这20张表)
导致报错，不知道锁定那张表

3.解决方案

看一下自己的分片策略，是否能够匹配到真实的表
