Hibernate使用注解进行查询，报错

[safari_W]

使用注解方式进行查询，Department.java文件如下：


Staff.java文件：


测试代码和hibernate.cfg.xml文件映射配置如下：


运行测试代码：


Junit报错：


求教各位大神是因为什么，如何解决呢？
把注解删掉，添加对应的xml映射文件可以运行，但是使用注解方式就会有如上报错，更新了hibernate.cfg.xml的版本也不行，求教如何解决TvT

问题已解决。 再次新建项目更新版本之后发现依旧报错，错误和原来一样，排除版本问题。 查看lib包发现包内jar包过多，删除无用包后Junit运行报错：Error applying BeanValidation relational constraints 错误如下： java.lang.ExceptionInInitializerError at test.JavaTest1.test1(JavaTest1.java:20) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.internal.runners.TestMethod.invoke(TestMethod.java:59) at org.junit.internal.runners.MethodRoadie.runTestMethod(MethodRoadie.java:98) at org.junit.internal.runners.MethodRoadie$2.run(MethodRoadie.java:79) at org.junit.internal.runners.MethodRoadie.runBeforesThenTestThenAfters(MethodRoadie.java:87) at org.junit.internal.runners.MethodRoadie.runTest(MethodRoadie.java:77) at org.junit.internal.runners.MethodRoadie.run(MethodRoadie.java:42) at org.junit.internal.runners.JUnit4ClassRunner.invokeTestMethod(JUnit4ClassRunner.java:88) at org.junit.internal.runners.JUnit4ClassRunner.runMethods(JUnit4ClassRunner.java:51) at org.junit.internal.runners.JUnit4ClassRunner$1.run(JUnit4ClassRunner.java:44) at org.junit.internal.runners.ClassRoadie.runUnprotected(ClassRoadie.java:27) at org.junit.internal.runners.ClassRoadie.runProtected(ClassRoadie.java:37) at org.junit.internal.runners.JUnit4ClassRunner.run(JUnit4ClassRunner.java:42) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) Caused by: org.hibernate.HibernateException: Error applying BeanValidation relational constraints at org.hibernate.cfg.beanvalidation.BeanValidationIntegrator.applyRelationalConstraints(BeanValidationIntegrator.java:219) at org.hibernate.cfg.beanvalidation.BeanValidationIntegrator.integrate(BeanValidationIntegrator.java:126) at org.hibernate.internal.SessionFactoryImpl.<init>(SessionFactoryImpl.java:306) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1744) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1782) at util.HibernateUtil.<clinit>(HibernateUtil.java:18) ... 23 more Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.hibernate.cfg.beanvalidation.BeanValidationIntegrator.applyRelationalConstraints(BeanValidationIntegrator.java:208) ... 28 more Caused by: org.hibernate.HibernateException: Unable to build the default ValidatorFactory at org.hibernate.cfg.beanvalidation.TypeSafeActivator.getValidatorFactory(TypeSafeActivator.java:524) at org.hibernate.cfg.beanvalidation.TypeSafeActivator.applyDDL(TypeSafeActivator.java:119) ... 33 more Caused by: javax.validation.ValidationException: Unable to instantiate Configuration. at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:272) at javax.validation.Validation.buildDefaultValidatorFactory(Validation.java:111) at org.hibernate.cfg.beanvalidation.TypeSafeActivator.getValidatorFactory(TypeSafeActivator.java:521) ... 34 more Caused by: java.lang.NullPointerException at java.util.ResourceBundle.getBundle(ResourceBundle.java:960) at org.hibernate.validator.engine.ResourceBundleMessageInterpolator.loadBundle(ResourceBundleMessageInterpolator.java:202) at org.hibernate.validator.engine.ResourceBundleMessageInterpolator.getFileBasedResourceBundle(ResourceBundleMessageInterpolator.java:182) at org.hibernate.validator.engine.ResourceBundleMessageInterpolator.<init>(ResourceBundleMessageInterpolator.java:81) at org.hibernate.validator.engine.ResourceBundleMessageInterpolator.<init>(ResourceBundleMessageInterpolator.java:73) at org.hibernate.validator.engine.ConfigurationImpl.<init>(ConfigurationImpl.java:57) at org.hibernate.validator.HibernateValidator.createGenericConfiguration(HibernateValidator.java:43) at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:269) ... 36 more 查询后发现：在hibernate.hbm.xml中加上 <property name="javax.persistence.validation.mode">none</property> javax.persistence.validation.mode默认情况下是auto的，就是说如果不设置的话它是会自动去你的classpath下面找一个bean-validation**包，但是找不到，所以beanvalitionFactory错误 原链接：https://blog.csdn.net/sivyer123/article/details/9185325 感谢大佬！
