错误产生的原因就是：我有一条sql在数据库执行，很长时间，刚好的delete操作，然后这边项目中刚好执行一条批量新增的sql，两者超时冲突了。

所以说这两者就涉及到事务锁的问题的了，接口响应时间超长，耗时几十秒才返回错误提示，后台日志中出现`Lock wait timeout exceeded; try restarting transaction`的错误，出现了高并发现象。

那么我们来说说如何解决方案：

当务之急，也是要看看数据库中有没有比较长时间执行的sql：

show  processlist;

当前所运行的所有事务

SELECT * FROM information_schema.INNODB_TRX;

当前所有的锁

SELECT * FROM information_schema.INNODB_LOCKs;

锁等待的对应的关系

SELECT * FROM information_schema.INNODB_LOCK_waits;

那么我们看到事务表中INNODB\_TRX，里面是否有正在锁定的事务线程，看看ID是否在show processlist里面的sleep线程中，如果有，那么就证明了这个休眠的线程事务一直没有commit（提交）或者roolback（回滚）而是卡住了，所以，我们需要人为介入，kill掉。
