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.<clinit>(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.<init>(ClassPathXmlApplicationContext.java:139) org.springframework.context.support.ClassPathXmlApplicationContext.<init>(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上执行一个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<User> fetchAllPersons() { return getUserDao().selectAll(); } }
其中使用userDao来查找实体:
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<User> selectAll() { Query query = entityManager.createQuery(SELECT_QUERY); @SuppressWarnings("unchecked") List<User> users = (List<User>) query.getResultList(); return users; } }
我在/ src / main / resources中有以下spring-config.xml:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <context:component-scan base-package="com.mydomain.orm" /> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerfactorybean"> <property name="persistenceXmlLocation" value="classpath:/persistence.xml" /> <property name="persistenceUnitName" value="userPersistenceUnit" /> <property name="dataSource" ref="dataSource" /> <property name="jpaVendorAdapter" ref="jpaVendorAdapter" /> <property name="jpaDialect" ref="jpaDialect" /> </bean> <bean id="jpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> <property name="database" value="Hsql" /> <property name="databasePlatform" value="org.hibernate.dialect.HsqlDialect" /> </bean> <bean id="jpaDialect" class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" /> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> <property name="dataSource" ref="dataSource" /> <property name="jpaDialect" ref="jpaDialect" /> </bean> <tx:annotation-driven transaction-manager="transactionManager" /> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="org.postgresql.Driver" /> <property name="url" value="jdbc:postgresql://localhost:5432/mydb" /> <property name="username" value="my_user" /> <property name="password" value="" /> </bean> </beans>
最后但并非最不重要的是以下/src/main/resources/persistence.xml:
<?xml version="1.0" encoding="UTF-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0"> <persistence-unit name="userPersistenceUnit" transaction-type="RESOURCE_LOCAL" > <class>com.mydomain.orm.User</class> </persistence-unit> </persistence>
老实说,当这个问题解决的时候,我可能只是想得到一个JndiException.你认为还可能造成什么?
解决方法
我覆盖了hibernate-entitymanager的版本与hibernate-core相同.固定.
