Spring Junit4 Test

Posted 2020-06-26 hello-yz

捣鼓了差不多一天。。。终于把"No Session found for current thread"问题解决了

环境：Spring 4.0.6 RELEASE + Hibernate 4.2.2 Final

折腾记录如下：

1. 出现"No Session found for current thread"，查找配置文件中的sessionFactory配置，确认无误；

2. 检查写的测试用例，并尝试修改注解:@Transactional和@TransactionConfiguration，没解决；

3. 再检查DAO层代码和对应的entity，确认没问题；

4. 搜索"No Session found for current thread"，有人说是配置文件中需要加上<prop key="hibernate.current_session_context_class">thread</prop>

　　试了，结果没有了"No Session found for current thread"，但是出现了"HibernateException: contains is not valid without active transaction",表明没有事务，错误更大了。

5. 接着搜索，找到如下blogs:

根据以上博客内容，加上Service层代码，并测试通过，郁闷了。。。

在看到这个博客后，噢了一声，果断把extends AbstractJUnit4SpringContextTests换成extends AbstractTransactionalJUnit4SpringContextTests，这才把事务管理加进来了，也可以回滚了!

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext_persistence.xml")
@TransactionConfiguration(transactionManager = "transactionManager",defaultRollback = true)
public class ActionDAOImplTest extends AbstractTransactionalJUnit4SpringContextTests {

    @Autowired
    private ActionService actionServiceImpl;

    @Autowired
    private ActionDAO actionDAOImpl;

    @Test
    //@Rollback
    public void testAdd() throws Exception {
        Action action = new Action();
        action.setLoginDate(new Date());
        Thread.sleep(2000);
        action.setLogoffDate(new Date());
        action.setUserName("chris");
        action.setOperation("add;update;select");
        actionServiceImpl.recordAction(action);
        Action lookUpOne = actionServiceImpl.checkAction(4);
        Assert.assertEquals("right","add;update;select",lookUpOne.getOperation());
    }

    @Test
    @Rollback(value = false)
    public void testAdd2() throws Exception {
        Action action = new Action();
        action.setLoginDate(new Date());
        Thread.sleep(2000);
        action.setLogoffDate(new Date());
        action.setUserName("chris");
        action.setOperation("add;update;select");
        actionDAOImpl.save(action);
        Action lookUpOne = actionDAOImpl.find(8);
        Assert.assertEquals("right","add;update;select",lookUpOne.getOperation());
    }
}
