junit测试中的spring-data-jpa beanvalidation
在我最近的工作中，我使用了spring-data-jpa来利用提供的存储库。 当涉及到集成测试时，我无法配置（我假设）测试的spring上下文，并且作为结果beanvalidation在我的测试中不起作用。
我知道我可以注入validation器，并对我的注释进行unit testing，但事实并非如此。 我正在编写集成测试，并希望在支持DB的情况下测试存储库。
我准备了简单的项目来显示所有必要的项目文件。
当我运行测试时，2失败了，我不知道为什么，类路径上存在hibernatevalidation器。
Failed tests: insertWrongEmail(com.example.core.data.jpa.UserRepositoryTest): Expected ConstraintViolationException wasn't thrown. insertToShortPassword(com.example.core.data.jpa.UserRepositoryTest): Expected ConstraintViolationException wasn't thrown. [..]

源代码和mvn测试输出如下。
预先感谢您的帮助。

解决了
在@gunnar回答之后，我在repository.save之后更改了测试以刷新持久性上下文，并且它按预期工作。
对UserRepository的更改
//inject entity manager @PersistenceContext private EntityManager entityManager; //add flush after save in test method @Test public void insertWrongEmail() { //given user.setEmail("NOT_AN_EMAIL_ADDRESS"); //when try { userRepository.save(user); entityManager.flush(); fail("Expected ConstraintViolationException wasn't thrown.");
解决方案2
在得到@andyb的推荐后，我已经切换到eclipselink并且测试工作没有刷新。 这是我将采用的解决方案，我认为切换实现比使用变通方法更好。
我设法在本地重现问题中描述的问题，虽然在添加了缺少的get / set函数和UserRepository类之后:-)
经过一番挖掘后，我发现JPA ConstraintViolation与Rollback和Hibernate在与Bean Validation API结合使用时没有遵循JPA规范存在两个问题？
两者似乎都认为Hibernate没有正确抛出ConstraintValidationException 。
第二个问题的结果是缺陷HHH-8028 – entityManager.persist没有抛出针对Hibernate引发的ConstraintValidationException 。
为了确认这是同一个问题，我切换到一个简单的@GeneratedValue并传递了insertWrongEmail 。 insertToShortPassword仍然失败，但我把它归结为密码字段上缺少的@Size(min = 6) 。 添加之后，所有测试都通过了。
恢复到已配置的@GeneratedValue然后我将Hibernate替换为EclipseLink持久性框架。 两项测试都通过了，这似乎证实了之前问题的发现。 我所做的改变是：
pom.xml更改按照EclipseLink站点上的描述添加jpa工件
org.eclipse.persistence org.eclipse.persistence.jpa 2.4.0 compile
test-context.xml更改
切换到EclipseLinkJpaVendorAdapter
添加eclipselink.weaving属性，详见EclipseLinkJpaVendorAdapter而不是HibernateJpaVendorAdapter问题
User.java更改
我需要添加一个默认的无参数构造函数。 您可能已经在完整的User.java类中拥有一个。
在执行存储库操作后刷新持久性上下文可能会起到作用。 JPA仅在与数据库同步时调用Bean Validation，即在提交或刷新期间。
