JVM TI学习(1) 如何中断weblogic中stuck thread(2)
时间:2010-12-26 BlogJava 走走停停又三年
有了线程名、connection，我们就可以用下面的方法去中断挂死线程了，
1 public void terminateThread(String threadPattern){
2 if(vm != null){
3 List threads = vm.allThreads();
4 ThreadReference tr = null;
5 int loop = -1;
6 for(loop=0; loop<threads.size(); loop++){
7 if(tr.toString().indexOf(threadPattern) != -1){
8 tr.interrupt();
9 System.out.println(threadPattern + " is terminated!");
10 break;
11 }
12 }
13 if(loop == threads.size())
14 System.out.println("no matched thread was found in target VM!");
15 }
16 }
线程被中断的时候，会收到InterruptedExcetpion，比如我在测试中让线程sleep，然后利用上面的程序去中断sleep，收到的异常如下：
