spring4 + junit4 事物无法回滚

在使用junit 4 测试spring4代码时, 事物始终无法回滚, 即使已经在方法中增加了@Transactiona 和 @Rollback(true)标签, 但是每次执行后数据还是插入到数据库中.

异常代码:

 

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
({"classpath*:applicationContext*.xml"}) 
public class SysUserServiceTest extends AbstractJUnit4SpringContextTests {

    @Autowired
    private SysUserService sysUserService;
    @Test
    @Transactional
    @Rollback(true)
    public void testInsert() {
        SysUser user = new SysUser();
        user.setUserId(11);
        user.setName("dan");
        sysUserService.insert(user);
    }

}

 

分析:

测试代码继承了AbstractJUnit4SpringContextTests , 在AbstractJUnit4SpringContextTests 中已经存在事务,并且默认事务是自动提交,它覆盖了后来在方法中配置的事务, 另外就是在测试类已经使用了@RunWith, 所以测试类无需再继承AbstractJUnit4SpringContextTests

 

解决:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
({"classpath*:applicationContext*.xml"}) 
public class SysUserServiceTest {

    @Autowired
    private SysUserService sysUserService;
    
    

    @Test
    @Transactional
    @Rollback(true)
    public void testInsert() {
        SysUser user = new SysUser();
        user.setUserId(19);
        user.setName("dan");
        sysUserService.insert(user);
    }

}
