ThreadMXBean

示例代码

package com.insightfullogic.java8.concurrent;

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

/**

public class MutilThread {
    public static void main(String[] args) {
        // 获取Java线程管理MXBean
        ThreadMXBean threadMXBean = ManagementFactory.getThreadMXBean();
        // 不需要获取同步的monitor和synchronized信息，仅获取线程和线程堆栈信息
        ThreadInfo[] threadInfos = threadMXBean.dumpAllThreads(false, false);
        // 遍历打印线程ID和名称
        Arrays.stream(threadInfos).forEach(threadInfo -> System.out.println("[" + threadInfo.getThreadId() + "]" + threadInfo.getThreadName()));
    }
}

结果输出

[6]Monitor Ctrl-Break
[5]Attach Listener
[4]Signal Dispatcher
[3]Finalizer
[2]Reference Handler
[1]main
