打断正常运行的线程

package cn.meowrain;

import lombok.extern.slf4j.Slf4j;

@Slf4j
public class Main {
    public static void main(String[] args) {
        Thread t1 = new Thread(()->{

            while (true) {

            }
        });
        t1.start();
        log.info("{}", t1.getState());
        t1.interrupt();
    }
}

这样我们发现t1线程没有被main线程终止，还在运行

interrupt并不能主动停下一个线程

package cn.meowrain;

import lombok.extern.slf4j.Slf4j;

import java.util.concurrent.TimeUnit;

@Slf4j
public class Main {
    public static void main(String[] args) throws InterruptedException {
        Thread t1 = new Thread(() -> {

            while (true) {
                if (Thread.interrupted()) {
                    break;
                }
            }
            log.info("线程t1被interrupted");
        },"t1");

        t1.start();
        log.info("{}", t1.getState());
        t1.interrupt();
    }
}

我们可以获取状态，对循环进行终止

打断在TIME_WAITING状态的线程

package cn.meowrain;

import lombok.extern.slf4j.Slf4j;

import java.util.concurrent.TimeUnit;

@Slf4j
public class Main {
    public static void main(String[] args) throws InterruptedException {
        Thread t1 = new Thread(() -> {

            while (true) {
                try {
                    TimeUnit.SECONDS.sleep(3);
                } catch (InterruptedException e) {
                    log.info("线程t1被interrupted");

                    throw new RuntimeException(e);
                }
            }

        }, "t1");

        t1.start();
        TimeUnit.SECONDS.sleep(1);
        log.info("{}", t1.getState());
        t1.interrupt();
    }
}
