Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state. The collection’s state is no longer correct

1、问题描述:

项目多线程运用了Dictionary报错Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state

2、原因分析:

Dictionary被多个线程同时所修改导致的所措。

3、解决办法:

Dictionary换成ConCurrentDictionary。

ConCurrentDictionary内部实现了锁机制。不会报以上错误。如果要用Dictionary则需要自己加入锁机制

4、平台解决方法

重启服务,或重新生成mapper文件
