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. at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:585) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:483) at org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:306) at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:230) at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:302) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:202) at org.springframework.beans.factory.config.DependencyDescriptor.resolveCandidate(DependencyDescriptor.java:208) at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:1138) at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:1066) at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:585) ... 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
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 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> 有关示例,您可以参考arpitaggarwal/jsr-303 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
