ClassNotFoundException：org.hibernate.service.jndi.JndiException

我得到以下堆栈跟踪…

java.lang.ClassNotFoundException: org.hibernate.service.jndi.JndiException java.net.URLClassLoader$1.run(Unknown Source) java.net.URLClassLoader$1.run(Unknown Source) java.security.AccessController.doPrivileged(Native Method) java.net.URLClassLoader.findClass(Unknown Source) org.springframework.boot.loader.LaunchedURLClassLoader.findClass(LaunchedURLClassLoader.java:148) java.lang.ClassLoader.loadClass(Unknown Source) org.springframework.boot.loader.LaunchedURLClassLoader.doLoadClass(LaunchedURLClassLoader.java:131) org.springframework.boot.loader.LaunchedURLClassLoader.loadClass(LaunchedURLClassLoader.java:103) java.lang.ClassLoader.loadClass(Unknown Source) java.lang.Class.forName0(Native Method) java.lang.Class.forName(Unknown Source) org.jboss.logging.Logger$1.run(Logger.java:2252) java.security.AccessController.doPrivileged(Native Method) org.jboss.logging.Logger.getMessageLogger(Logger.java:2227) org.jboss.logging.Logger.getMessageLogger(Logger.java:2214) org.hibernate.ejb.Ejb3Configuration.(Ejb3Configuration.java:143) org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:74) org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean.createNativeEntityManagerFactory(LocalContainerEntityManagerFactoryBean.java:318) org.springframework.orm.jpa.AbstractEntityManagerFactoryBean.afterPropertiesSet(AbstractEntityManagerFactoryBean.java:317) org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1607) org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1544) org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:539) org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:475) org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:300) org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:228) org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:296) org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:195) org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:973) org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization(AbstractApplicationContext.java:750) org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:482) org.springframework.context.support.ClassPathXmlApplicationContext.(ClassPathXmlApplicationContext.java:139) org.springframework.context.support.ClassPathXmlApplicationContext.(ClassPathXmlApplicationContext.java:83) com.mydomain.GetController.getUser(GetController.java:20) sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) java.lang.reflect.Method.invoke(Unknown Source) org.springframework.web.method.support.InvocableHandlerMethod.invoke(InvocableHandlerMethod.java:214) org.springframework.web.method.support.InvocableHandlerMethod.invokeForRequest(InvocableHandlerMethod.java:132) org.springframework.web.servlet.mvc.method.annotation.ServletInvocableHandlerMethod.invokeAndHandle(ServletInvocableHandlerMethod.java:104) org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter.invokeHandleMethod(RequestMappingHandlerAdapter.java:748) org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter.handleInternal(RequestMappingHandlerAdapter.java:689) org.springframework.web.servlet.mvc.method.AbstractHandlerMethodAdapter.handle(AbstractHandlerMethodAdapter.java:83) org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:947) org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:878) org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:946) org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:837) javax.servlet.http.HttpServlet.service(HttpServlet.java:621) org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:822) javax.servlet.http.HttpServlet.service(HttpServlet.java:728) org.springframework.web.filter.HiddenHttpMethodFilter.doFilterInternal(HiddenHttpMethodFilter.java:77) org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:108) 

当我的Spring控制器处理连接时：

 @RequestMapping(value = "/user", method = RequestMethod.GET) public @ResponseBody User getUser(@RequestParam(value="id", required=true) int id) { User user = null; ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("spring-config.xml"); UserService userService = (UserService) context.getBean("userService"); user = userService.getUser(id); context.close(); return user; } 

它在userService上执行getUser：

 import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; @Component public class UserService { private UserDAO userDao; public UserDAO getUserDao() { return userDao; } @Autowired public void setUserDao(UserDAO userDao) { this.userDao = userDao; } public void addUser(User user) { getUserDao().insert(user); } public User getUser(int id) { return getUserDao().load(id); } public List fetchAllPersons() { return getUserDao().selectAll(); } } 

使用userDao查找实体：

 import java.util.List; import javax.persistence.EntityManager; import javax.persistence.PersistenceContext; import javax.persistence.Query; import org.springframework.stereotype.Repository; import org.springframework.transaction.annotation.Propagation; import org.springframework.transaction.annotation.Transactional; @Repository("userDao") @Transactional(propagation = Propagation.REQUIRED) public class UserDAO { private static final String SELECT_QUERY = "select u from users"; @Qualifier(value = "entityManagerFactory") private EntityManager entityManager; public EntityManager getEntityManager() { return entityManager; } public void setEntityManager(EntityManager entityManager) { this.entityManager = entityManager; } public void insert(User user) { entityManager.persist(user); } public User load(int id) { return entityManager.find(User.class, id); } public List selectAll() { Query query = entityManager.createQuery(SELECT_QUERY); @SuppressWarnings("unchecked") List users = (List) query.getResultList(); return users; } } 

我在/ src / main / resources中有以下spring-config.xml：

最后但并非最不重要的是以下/src/main/resources/persistence.xml：

    com.mydomain.orm.User   

我该怎么做才能解决此错误？

老实说，当这个问题得到解决时，我可能只会得到一个JndiException。 您认为可能会导致什么？

Answer 1

我将hibernate-entitymanager的版本覆盖为与hibernate-core相同。 固定。

Answer 2

如果您在pom.xml中使用hibernate-core和hibernate-entitymanager，则必须使用相同的版本。 我试过这个并解决了。

   org.hibernate hibernate-core 4.1.9.Final   org.hibernate hibernate-entitymanager 4.1.9.Final  

Answer 3

可能有两个原因：

1：类路径中缺少包含JNDIException的适当的hibernate lib

2：重复的hibernate.jars之间存在版本冲突。 如果尝试在已经提供相同库但具有不同版本的JEEContainer（服务器）中部署应用程序，则会发生这种情况。

当JNDIException类可以解决时，您的主要问题在错误消息中变得明显。

Answer 4

我会先尝试解决ClassNotFoundException。 错误消息可以让您更好地了解错误。

为此，请检查hibernate-core lib和hibernate-entitymanager lib的版本号。 还要确保你的hibernate版本与jboss hibernate版本没有冲突。
