synchronized在spring的bean中修饰方法

 synchronized修饰方法，在spring管理的bean中表现同样是获取当前对象的锁。

 通过controller调用thread1()，再发起另一个请求调用thread2()。

 等待thread1()执行完，才执行thread2()方法。

@Service
public class ThreadSafeServiceImpl implements ThreadSafeService {

    @Override
    public synchronized  Result thread1() {
        try {
            Thread.sleep(8000L);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("thread1 done");
        return null;
    }

    @Override
    public synchronized Result thread2() {
        System.out.println("thread2 done");
        return null;
    }
}

 

public interface ThreadSafeService {
    Result thread1();
    Result thread2();
}

thread1 done
thread2 done
