java Spring Boot JSR303/349配置

Question

在我的Spring Boot 1.5.1应用程序中，我试图配置对JSR-303/JSR-349验证的支持

我在我的方法中添加了以下注释@NotNull @Size(min = 1)：

@Service
@Transactional
public class DecisionDaoImpl extends BaseDao implements DecisionDao {

    @Override
    public Decision create(@NotNull @Size(min = 1) String name, String description, String url, String imageUrl, Decision parentDecision, Tenant tenant, User user) {
        ...
    }

}

我试图从测试中调用此方法，但它不会在验证约束条件下失败

这是我的测试和配置：

@SpringBootTest(classes = { TestConfig.class, Neo4jTestConfig.class })
@RunWith(SpringRunner.class)
@Transactional
public class TenantTest {

    @Test
    public void testCreateDecision() {
        User user1 = userService.createUser("test1", "test1", "test1@test.com", null, null);
        Tenant tenant1 = tenantDao.create("Tenant 1", "Tenant 1 description", false, user1);

        // the following line should fail on the validation constraint because name parameter is null but it doesn't
        final Decision rootDecision = decisionDao.create(null, "Root decision 1 description", null, tenant1, user1);

...


@Configuration
@ComponentScan("com.example")
@SpringBootApplication(exclude={Neo4jDataAutoConfiguration.class})
public class TestConfig {
}

我做错了什么，以及如何在那里配置JSR-303

更新

我补充说

public Decision create(@Valid @NotNull @Size(min = 1) String name, String description, Decision parentDecision, Tenant tenant, User author) {

但它仍然不起作用

我已经将@Validated添加到我的DecisionDaoImpl中，但现在失败了，出现了以下异常：

Caused by: org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'decisionDaoImpl': Bean with name 'decisionDaoImpl' has been injected into other beans [criterionGroupDaoImpl,characteristicGroupDaoImpl,tenantDaoImpl] in its raw version as part of a circular reference, but has eventually been wrapped. This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching - consider using 'getBeanNamesOfType' with the 'allowEagerInit' flag turned off, for example.

我还在自动连接我的DecisionDao的地方添加了@Lazy注释，但现在我的测试失败了，出现了以下异常：

javax.validation.ConstraintDeclarationException: HV000151: A method overriding another method must not alter the parameter constraint configuration, but method public com.example.domain.model.entity.decision.Decision com.example.domain.dao.decision.DecisionDaoImpl.create(java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.Long,java.lang.Long,com.example.domain.model.entity.user.User) changes the configuration of public abstract com.example.domain.model.entity.decision.Decision com.example.domain.dao.decision.DecisionDao.create(java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.Long,java.lang.Long,com.example.domain.model.entity.user.User).

约束注释旨在应用于JavaBeans。见http://beanvalidation.org/1.0/spec/#constraintsdefinitionimplementation-constraintdefinition

在DAO中应用了约束注释@NotNull、@Size等。您必须创建一个Java Bean，例如“Person”，它包装这些属性（名称、描述等），然后将“Person”作为参数传递给控制器方法。如果需要使用DAO而不是控制器，则需要对其进行检测以执行验证。在AOP等方面，你可能需要依靠自己，除非这篇文章之后发生了变化：http://forum.spring.io/forum/spring-projects/container/82643-annotation-driven-jsr-303-validation-on-service-and-dao-tier

更新：看起来现在支持它（方法级验证JSR-349），请参见http://blog.codeleak.pl/2012/03/how-to-method-level-validation-in.html以获取类似于Arpit答案的示例。 更新了问题标题，以反映最新的JSR
