jdbc批量更新时死锁.
java.sql.BatchUpdateException: Batch entry 910 UPDATESQL语句 was aborted：ERROR：deadlock detected
详细： Process 157988 waites for ShareLock on transaction 7944777; blocked by process 157400.
Process 157400 waites for ShareLock on transaction 7944775; blocked by process 157988.
建议：see server log for query details.
在位置：while updatingq tuple(1149,7)
in relation “table_name” Call getNextException to see other errors in batch.

死锁了(deadlock detected)！
检查代码未见死锁代码,提示也指向数据库死锁.
推测是锁表导致的,单个updateById不会锁边,jdbc的批量更新.所以可能未执行索引.
加锁后,果然死锁消失.
记一次锁表导致的死锁异常.
