获取java中jvm启动的线程信息

import java.lang.management.ManagementFactory;
import java.lang.management.ThreadInfo;
import java.lang.management.ThreadMXBean;

public class MultiThread {

public static void main(String[] args){
//获取java的线程管理MXBean
ThreadMXBean threadBean = ManagementFactory.getThreadMXBean();
//不需要获取同步的monitor和synchronizer信息，仅获取线程和线程堆栈信息
ThreadInfo[] threadInfo = threadBean.dumpAllThreads(false, false);
//遍历线程信息，仅打印线程id和线程名称信息
for(ThreadInfo info : threadInfo){
System.out.println(info.getThreadId() + "--" + info.getThreadName() +"--"+ info.getThreadState().name());
}
}
