在run方法中，如何查找从何处开始? [英] In run method, how to find from where start was called?

问题描述

我正在调试一些代码.我的调试器显示代码的来源是Thread.run().我需要知道从哪一部分代码Thread.start()调用了！有办法找出答案吗?

I am debugging some code. My debugger shows that the origin of code is from Thread.run(). I need to know from which part of code Thread.start() was called! Is there a way to find this out?

推荐答案

您可以使用new Throwable().getStackTrace()获取完整的堆栈跟踪.要获取start堆栈，您必须扩展Thread，这是实际上有必要进行的几次扩展(最好使用Runnable).

You can use new Throwable().getStackTrace() to get a full stack trace. To get the start stack you must extend Thread, one of the few times it is actually necessary to do so (mostly using Runnable is preferred).

class C extends Thread {
    StackTraceElement[] constructed;
    StackTraceElement[] started;

    public C() {
        constructed = new Throwable().getStackTrace();
    }

    @Override
    public void run() {
        // Your suuff.
    }

    @Override
    public synchronized void start() {
        started = new Throwable().getStackTrace();
        super.start();
    }

}
