Spring Boot JSR-303 / 349配置

Spring Boot JSR-303 / 349配置

spring-boot

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) {
        ...
    }

}

我正在尝试从测试中调用此方法，但在验证约束上它不会失败。

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 {
}

我在做什么错，以及如何在其中配置JSR-303？

更新

我已经添加了

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

我已添加@Validated到我的应用程序，DecisionDaoImpl但现在失败，但出现以下异常：

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.

我还在@Lazy自动装配的地方添加了注释，DecisionDao但是现在我的测试失败，但有以下异常：

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).

将验证移至界面，如下所示：

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 description, String url, String imageUrl);
}

注释你DecisionDaoImpl有@Validated，具体如下：

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 description, String url, String imageUrl) {
        System.out.println(name);
        return new Decision();
    }

}

修改测试用例以验证是否javax.validation.ConstraintViolationException使用assertj或ExpectedException，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,
                                "Root decision 1 description", null, null));
    }

    @Test
    public void testCreateDecision() {
       expectedException.expect(ConstraintViolationException.class);
       decisionDao.create(null, "Root decision 1 description", null, null);
    }

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

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

确保您的类路径中有 hibernate-validator 以及@StanislavL答案：

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

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

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