this method, the thread has not finished, it will be forced to stop, you think, if this happens in our database of a transaction to operate, what will happen?The correct way to exit a thread is to set a flag bit keeprunning, when the thread executes when Keeprunning=true is Keeprunning=false, and the thread exits, so that the thread exits the thread after execution. This ensures thread security, which is the recommended way to exit threads.Some people say that the interrupt () method can also s
