java – Spring Boot JSR-303/349配置

在我的 Spring Boot 1.5.1应用程序中,我正在尝试配置对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) {
        ...
    }

}

我试图从我的测试中调用此方法,但它不会在验证约束上失败.

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",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

我已经添加了

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

但它仍然无效

我已将@Validated添加到我的DecisionDaoImpl中,但它现在失败并出现以下异常：

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.

    ... 43 common frames omitted

我还在我自动装配DecisionDao的地方添加了@Lazy注释,但是现在我的测试失败并出现以下异常：

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.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,com.example.domain.model.entity.user.User).
    at org.hibernate.validator.internal.metadata.aggregated.rule.OverridingMethodMustNotAlterParameterConstraints.apply(OverridingMethodMustNotAlterParameterConstraints.java:24)
    at org.hibernate.validator.internal.metadata.aggregated.ExecutableMetaData$Builder.assertCorrectnessOfConfiguration(ExecutableMetaData.java:456)

解决方法

import javax.validation.Valid;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

public interface DecisionDao {

     Decision create(@Valid @NotNull @Size(min = 1) String name,String imageUrl);
}

使用@Validated注释DecisionDaoImpl,如下所示：

import org.springframework.stereotype.Service;
import org.springframework.validation.annotation.Validated;

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

    @Override
    public Decision create(String name,String imageUrl) {
        System.out.println(name);
        return new Decision();
    }

}

使用assertj或ExpectedException修改测试用例以验证javax.validation.ConstraintViolationException,如下所示：

import static org.assertj.core.api.Assertions.assertThatExceptionOfType;

import javax.validation.ConstraintViolationException;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.validation.beanvalidation.MethodValidationPostProcessor;

@ContextConfiguration(classes = { TenantTest.Config.class })
@RunWith(SpringRunner.class)
public class TenantTest {

    @Autowired
    private DecisionDao decisionDao;

    @Rule
    public ExpectedException expectedException = ExpectedException.none();

    @Test
    public void testCreateDecisionUsingAssertj() {
        assertThatExceptionOfType(ConstraintViolationException.class)
                .isThrownBy(
                        () -> decisionDao.create(null,null));
    }

    @Test
    public void testCreateDecision() {
       expectedException.expect(ConstraintViolationException.class);
       decisionDao.create(null,null);
    }

    @Configuration
    public static class Config {
        @Bean
        public MethodValidationPostProcessor methodValidationPostProcessor() {
            return new MethodValidationPostProcessor();
        }

        @Bean
        public DecisionDao decisionDao() {
            return new DecisionDaoImpl();
        }
    }
}

确保你的类路径中有hibernate-validator和@StanislavL答案：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
</dependency>

以及org.assertj.core.api.Assertions.assertThatExceptionOfType的可选依赖项,如：

<dependency>
     <groupId>org.assertj</groupId>
     <artifactId>assertj-core</artifactId>
     <version>3.3.0</version>
     <scope>test</scope>
</dependency>
