使用synchronized产生死锁

public void sync() {final Object object1 = new Object();final Object object2 = new Object();Executor executor = Executors.newFixedThreadPool(2);executor.execute(new Runnable() {public void run() {synchronized (object1) {System.out.println("线程1 获取锁1");ThreadUtils.sleep(1000);synchronized (object2) {System.out.println("线程1 获取锁2");}}}});executor.execute(new Runnable() {public void run() {synchronized (object2) {System.out.println("线程2 获取锁2");synchronized (object1) {System.out.println("线程2 获取锁1");}}}});}

程序输入结果

线程1 获取锁1
线程2 获取锁2

通过jconsole查看 线程 并可以检查已经发生死锁
