Spring transactionManager正在回滚，而testexception = [null]！

Question

为什么在没有Exception的情况下回滚事务？该对象未被保存。 我已经定义了交易参数，如：

 @Transactional(value = "transactionManager", timeout = 30, rollbackFor =
 java.lang.Exception.class)`.  

这就是日志对交易的评价。

org.springframework.test.context.transaction.TransactionalTestExecutionListener
endTransaction
INFO: Rolled back transaction after test execution for test context [TestContext@51e2a069
testClass = DAOTest, testInstance = sample.library.dao.DAOTest@7591777e, testMethod =
testSaveDao@DAOTest, testException = [null], mergedContextConfiguration =
[MergedContextConfiguration@213c2d7f testClass = DAOTest, locations = 
'{classpath:/applicationcontext.xml}', classes = '{}', contextInitializerClasses = '[]',
activeProfiles = '{}', contextLoader = 
'org.springframework.test.context.support.DelegatingSmartContextLoader', parent =
[null]]]
Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 3.634 sec

以下是DAOTest类的整个日志：

-------------------------------------------------------------------------------
Test set: sample.library.dao.DAOTest
-------------------------------------------------------------------------------
Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 3.634 sec

做错了什么？如有必要，我可以提供更多信息。

INFO级别应该提示这不是错误消息。无论服务级别方法的主要设置如何，您的测试都会默认回滚。为了避免回滚（如果你真的想要），你需要在测试类本身上有一个注释，如Spring文档中的Annotations section of the Testing chapter中所述。有问题的注释是@Rollback。
