【IT168 技术文档】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!
