【问题描述】：

我在我的实体中使用 Hibernate-validator 注释，这会导致我的 Junit 测试出现异常。如果我使用属性禁用休眠验证：

<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？

【解决方案1】：

原因：java.lang.ClassFormatError: Absent Code attribute ...

表示您使用的 jar 仅包含类和方法签名，但不包含方法实现。

通常是因为从http://download.java.net/maven/2/ 使用javaee-api.jar。

删除这个罐子！（并在需要时将其替换为包含代码的正确 jar）
