Question

我在我的实体中使用了Hibernate-validator注释，这导致我的Junit测试中出现异常。如果我使用属性禁用hibernate验证：

<prop key="javax.persistence.validation.mode">none</prop>

然后Junit测试工作得很好，否则我收到以下错误：

JUnit测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring-config-test.xml")
@Transactional
public class BaseTest {

    @Test
    public void init () {
      Assert.assertEquals(15,15);
    }
}

有什么建议吗？

引起：java.lang.ClassFormatError：缺少代码属性......

表示您使用的jar只包含类和方法签名，但不包含方法实现。

通常原因是一个人使用http://download.java.net/maven/2/中的javaee-api.jar。

删除这个罐子！（并在需要时，将其替换为包含代码的右侧罐子）
