java - 多线程ThreadLocal相关求助

Question

当前项目的connection都是放在ThreadLocal里面的。由于我的某个功能操作有部分打算异步处理，new Thread(()->{//.......}).start() 这样就导致无法使用dao了。因为dao需要的connection在ThreadLocal中。

Answer 1

The connection must be released after each use. The next time you connect, just go to threadlocal to get the value. I don’t understand what you mean.

Answer 2

When creating a new Thread, take the connection out of ThreadLocal and pass it in

Answer 3

Isn’t there a way to get the connection?

Answer 4

Just write the execution part independently, so you don’t need to pass the dao to Thread

Answer 5

If this asynchronous operation is non-transaction related to the previous logic. That is to say, they are not in the same transaction.
Then you can use a new link.

If there is a transaction, this old link must be used. This connection object can only be passed to the thread.
