如何使用JAVA代码以编程方式捕获线程转储？ [英] How to capture thread dump programatically using JAVA Code?

问题描述

我想通过java代码生成线程转储，我尝试使用ThreadMXBean但是我没有以正确的格式获得线程转储，因为我们正在使用 jstack 命令。请任何人提供一些帮助..是他们的任何其他方式来获取线程转储...使用任何其他API ..我想要的线程转储的格式是 -

解决方案

尝试 ManagementFactory.getThreadMXBean（）。dumpAllThreads（true，true）使用

  ThreadMXBean bean = ManagementFactory.getThreadMXBean（）; 
 ThreadInfo [] infos = bean.dumpAllThreads（true，true）; 
 for（ThreadInfo info：infos）{
 System.out.println（info）; 
} 
  

或者你可以破解方式并实际调用 jstack 通过 Runtime.getRuntime.exec（）：

  String pid = ManagementFactory.getRuntimeMXBean（）。getName（）。replaceAll（[^ \\d。]，）; 
 InputStream in = Runtime.getRuntime（）。exec（PATH_TO_JSTACK ++ pid）.getInputStream（）; 
 System.out.println（IOUtils.toString（InputStream））;

解决方案

Try ManagementFactory.getThreadMXBean().dumpAllThreads(true, true) using something like

ThreadMXBean bean = ManagementFactory.getThreadMXBean();
ThreadInfo[] infos = bean.dumpAllThreads(true, true);
for (ThreadInfo info : infos) {
   System.out.println(info);
}

Alternatively you can hack your way around and actually call jstack through Runtime.getRuntime.exec():

String pid = ManagementFactory.getRuntimeMXBean().getName().replaceAll("[^\\d.]", "");
InputStream in = Runtime.getRuntime().exec(PATH_TO_JSTACK + " " + pid).getInputStream();
System.out.println(IOUtils.toString(InputStream));
