看到的一个解决方法,代码如下:
public class MyThreadTest { final static private long THREAD_MAX_RUNTIME = 1000; final static private long THREAD_WAITTIME = 200; private MyThread myThread1 = null; private MyThread myThread2 = null; @Before public void setUp() throws Exception { myThread1 = new MyThread(); myThread2 = new MyThread(); } @Test(timeout = THREAD_MAX_RUNTIME) public void testRun() throws Exception { Thread t1 = new Thread(myThread1); Thread t2 = new Thread(myThread2); t1.start(); t2.start(); Thread tc = Thread.currentThread(); synchronized (tc) { while (t1.isAlive() || t2.isAlive()) { tc.wait(THREAD_WAITTIME); } tc.notify(); } Assert.assertEquals(100, myThread1.getI()); Assert.assertEquals(100, myThread2.getI()); } } |
另外我发现,当使用二级缓存时,Hibernate的load方法是不会抛出乐观锁错误,因为load返回的只是一个代理,等到真正要使用的时候,他才去缓存中拿,而且拿到的一定是最新的状态!
