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) {
...
}
}
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.

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
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 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>
