我正在进行单元测试,我希望所有提交给MySQL数据库的数据都将被回滚......但事实并非如此.即使我的日志显示正在发生回滚,也会提交数据.我已经和它摔跤了几天,所以我的设置已经改变了很多,这是我目前的设置.
LoginDAOTest.java:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"file:web/WEB-INF/applicationContext-test.xml", "file:web/WEB-INF/dispatcher-servlet-test.xml"})
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
public class UserServiceTest {
private UserService userService;
@Test
public void should_return_true_when_user_is_logged_in ()
throws Exception
{
String[] usernames = {"a","b","c","d"};
for (String username : usernames)
{
userService.logUserIn(username);
assertThat(userService.isUserLoggedIn(username), is(equalTo(true)));
}
}

为什么我需要所有这些括号？
假设我已经有了一个有效的Spring项目,那么使用Spring 3 XML配置在Hibernate 4中添加的最小配置量是多少？我想使用基于注释的事务管理,并使用注释来映射我的对象.
注意:这是一个自我回答问答风格的问题,旨在为常见问题提供规范的答案.我打算随着时间的推移扩展这个问题,以便与Hibernate保持同步.
