在自定义jsr验证器中自动装配

标签： java spring jpa bean-validation

所以我按照这个page的文档来使自定义jsr验证器中的依赖注入工作。据我所知，我需要在我的配置中添加一个LocalValidatorFactoryBean，我在这里做了：

    @Configuration
public class ValidatorConfig {

    //Used to make sure custom validators get picked up
    @Bean
    public LocalValidatorFactoryBean validator(){
        return new LocalValidatorFactoryBean();
    }
}

这适用于我的所有测试套件，除了一个：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class, classes = JpaConfig.class)
@ActiveProfiles(Profiles.TEST)
public class UserLifeCycleTestCase {

    @Autowired
    private UserJpaRepository userJpaRepository;

    @Autowired
    private CountryJpaRepository countryJpaRepository;

    @Test
    public void ageShouldBeCorrectBecauseEntityIsPeristed(){
        User user = new User("robin.hellemans@www.com", "Robin0", "Robin", "Hellemans", new Date(), "Molens", 85, "AbcTown", "1000", countryJpaRepository.findOne(1L));
        userJpaRepository.saveAndFlush(user);
        assertNotNull(user.getPerson().getAge());
    }
}

JpaConfig.class的相关部分：

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "com.robin.repository")
@EnableJpaAuditing
//Picks up other @Configuration classes as well
@ComponentScan(basePackages = "com.robin")
public class JpaConfig {

在此测试用例中，JpaRepository（它是一个Spring Data Jpa存储库）为null。验证器:(我怀疑它有什么问题，因为其他测试用例也依赖于这个并成功运行）

public class UniqueUserNameValidator implements ConstraintValidator<UniqueUserName, String>{

    @Autowired
    private UserJpaRepository userJpaRepository;

    @Override
    public void initialize(UniqueUserName constraintAnnotation) {

    }
@Override
public boolean isValid(String value, ConstraintValidatorContext context) {
    return userJpaRepository.findByUserName(value) == null;
}

}

在我的其他测试套装中，情况并非如此，这是我的repo的自动装配示例（注意相同的配置）：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class, classes = JpaConfig.class)
@ActiveProfiles(Profiles.TEST)
public class CountryValidationTestCase {

    @Autowired
    private Validator validator;

      //Tests

查看文档，我没有做错任何事，所以我真的无法在这里看到问题。

编辑：stacktrace：

我最终通过将LocalValidatorFactoryBean放在jpaPropertyMap中并将其设置在我的LocalContainerEntityManagerFactoryBean上来修复此问题：

Map<String, LocalValidatorFactoryBean> jpaPropertyMap = new HashMap<>();
    jpaPropertyMap.put("javax.persistence.validation.factory", localValidatorFactoryBean);
    factoryBean.setJpaPropertyMap(jpaPropertyMap);

奇怪的是文档中没有说明这一点......
