idea中多线程调试技巧

示例代码

public class Lesson091 {
    public static void main(String[] args) {
        //下面创建3个线程：thread1、thread2、thread3
        Thread thread1 = new Thread(() -> {
            for (int i = 0; i < 50; i++) {
                System.out.println(Thread.currentThread() + " " + i);
            }
        }, "thread1");

        Thread thread2 = new Thread(() -> {
            for (int i = 0; i < 50; i++) {
                System.out.println(Thread.currentThread() + " " + i);
            }
        }, "thread2");

        Thread thread3 = new Thread(() -> {
            for (int i = 0; i < 50; i++) {
                System.out.println(Thread.currentThread() + " " + i);
            }
        }, "thread3");

        thread1.start();
        thread2.start();
        thread3.start();
    }
}

idea 设置如下

效果如下，点击切换，就单独调试某个线程
