无法回滚，连接已关闭

新手上路，请多包涵

最近我将我所有的 jar 文件升级到最新版本（Spring 4.2.x、JPA 和 Hibernate）

现在我在测试用例方面遇到了一些问题。这是测试的堆栈跟踪…

它说连接已关闭….并且无法回滚。来自休眠的池连接是否自动关闭连接？有谁知道这是什么原因造成的？

编辑：添加了测试代码（如果需要更多信息，测试很大，我将再次编辑）

 @RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "testConfig.xml" })
@Transactional
@TransactionConfiguration(transactionManager = "test.txManager", defaultRollback = true)
public class ControllerTest {
... logs ...

    @Autowired
    private Controller controller;
    static final String testIdValue = "114294";
    ... other decorations...

    private Request createRequest() throws Exception {
        Request r = new Request();
        r.setTask(true);
        other set for test values...
        r.assignTaskList(...);
        ...
        return r;
    }

    @Test
    public void assignEndpointsForsSynchTest() throws Exception {

        Request req = createRequest();

        try {
            Response resp = Controller
                    .assignTask(req);
            assertTrue(req.SUCCESSFUL);
        } catch (Exception e) {
            log.info(e.getMessage());
            fail("Unexpected Exception");
        }
    }

}

请停止在服务器模式下使用 H2，在嵌入式模式下使用它以支持@Transactional 回滚。

抛出上述异常是因为服务器模式下的H2不支持事务回滚，默认是auto-commit。执行查询后，它会自动提交并关闭会话。因此回滚导致抛出异常。

要在嵌入式模式下使用 H2，请将 jar 添加到类路径并将数据源 bean 替换为 <jdbc:embedded-database id="dataSource" type="H2" /> 。在您的情况下，该值将为 id="test.dataSource" 。

以下是在服务器模式下使用 H2 时的一些已知问题：

我的建议是使用一个能够很好地支持带有提交和回滚测试的事务的数据库，例如 MySQL InnoDB 。

如果您在尝试此操作后仍然继续遇到异常，请告诉我。
