lockInterruptibly的简单使用

lockInterruptibly是中断获取锁的操作，可以让线程去干别的事情

 

 代码部分

package com.java.test.lock;

import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

@RestController
public class LockDemo {

    private Lock lock = new ReentrantLock();

    @RequestMapping("/lockInterruptiblyThreadOne")
    public String lockInterruptiblyThreadOne() throws InterruptedException {
        LockDemo lockDemo=new LockDemo();
        Thread t0 = new Thread(
                new Runnable() {
                    @Override
                    public void run() {
                        lockDemo.doBussiness();
                    }
                }
        );
        // 启动线程t0
        t0.start();
        Thread.sleep(10);
        return "启动线程t1";
    }

    @RequestMapping("/lockInterruptiblyThreadTwo")
    public String lockInterruptiblyThreadTwo() throws InterruptedException {
        LockDemo lockDemo=new LockDemo();

        Thread t1 = new Thread(
                new Runnable() {
                    @Override
                    public void run() {
                        lockDemo.doBussiness();
                        dealWith();
                    }
                }
        );
        // 启动线程t1
        t1.start();
        Thread.sleep(100);
        // 线程t1没有得到锁，中断t1的等待
        t1.interrupt();
        return "启动线程t1";
    }




    public void doBussiness() {
        String name = Thread.currentThread().getName();

        try {
            log.info(name + " 开始获取锁");
            lock.lockInterruptibly();
            log.info(name + " 得到锁");
            log.info(name + " 开工干活");
            for (int i = 0; i < 10; i++) {
                Thread.sleep(2000);
                log.info(name + " : " + i);
            }
        } catch (InterruptedException e) {
            log.info(name + " 被中断");
            log.info(name + " 做些别的事情");
        } finally {
            try {
                lock.unlock();
                log.info(name + " 释放锁");
            } catch (Exception e) {
                log.info(name + " : 没有得到锁的线程运行结束");
            }
        }
    }

    public void dealWith(){
        log.info("中断获取锁的操作后，开始做的事情.....");
    }


}
