推荐答案

Java线程转储是一种查找JVM中每个线程在特定时间点执行操作的方法。如果您的Java应用程序在加载下运行时有时似乎挂起，这尤其有用，因为对转储的分析将显示线程被卡住的位置。

A Java thread dump is a way of finding out what every thread in the JVM is doing at a particular point in time. This is especially useful if your Java application sometimes seems to hang when running under load, as an analysis of the dump will show where the threads are stuck.

您可以生成一个通过运行 kill -QUIT< pid> ，并在下的 Unix / Linux 下的线程转储Windows ，点击 Ctl + Break 。

You can generate a thread dump under Unix/Linux by running kill -QUIT <pid>, and under Windows by hitting Ctl + Break.
