    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<User> 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<User> selectAll() {
        Query query = entityManager.createQuery(SELECT_QUERY);
        @SuppressWarnings("unchecked")
        List<User> users = (List<User>) query.getResultList();
        return users;
    }

}

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

<?xml version="1.0" encoding="UTF-8"?>

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>

我需要怎么做才能解决此错误？

不过，老实说，解决此问题后，我可能只会得到JndiException。您认为是什么原因造成的？

ClassNotFoundException：组织hibernate.collection.PersistentSet + Hibernate 5.4

ClassNotFoundException：组织hibernate.collection.PersistentSet + Hibernate 5.4

如何解决ClassNotFoundException：组织hibernate.collection.PersistentSet + Hibernate 5.4？

我们正在从3级迁移到5.4版。进行所有更改后，模块运行正常，因此我合并了其他修复程序的代码。

发布此消息后，我收到一些正在处理的消息的奇怪异常。

试图找出根本原因，但无法找出为什么要引用休眠3类。。我们发送的对象具有一对多关系

我们的应用程序正在从JMS队列中读取消息，在下面，尽管没有使用过此类，但它引发了异常

Serializable obj =((ObjectMessage) message).getobject()

例外：抱歉，无法添加整个跟踪

Weblogic.jms.common.JMSException[JMSClientExceptions:055115]Error deserializing an object

它在我的HibernateUtil类中命中了NPE，第53行是创建EntityManager的行-
看起来createEntityManager（）返回的是null。代码看起来像

private static EntityManagerFactory entityManagerFactory = null;
private static EntityManager entityManager = null;

static {
    try {

        entityManagerFactory = Persistence.createEntityManagerFactory("primary");
        entityManager = entityManagerFactory.createEntityManager();

我的persistence.xml看起来像

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"> <persistence-unit name="primary"> <jta-data-source>java:jboss/datasources/MySqlDS</jta-data-source>

  <properties>
     <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
     <property name="hibernate.ejb.interceptor.session_scoped" value="com.mycompany.myapp.common.persistence.BusinessObjectInterceptor"/>
           </properties>

有什么想法为什么createEntityManager（）给NPE？

我们今天的关于java.lang.ClassNotFoundException：org.hibernate.bytecode.instrumentation.internal.FieldInterceptionHelper的分享已经告一段落，感谢您的关注，如果您想了解更多关于ClassNotFoundException：org.hibernate.service.jndi.JndiException、ClassNotFoundException：组织hibernate.collection.PersistentSet + Hibernate 5.4、could not execute statement； SQL [n/a]； nested exception is org.hibernate.exception.DataException:、createEntityManager在org.hibernate.engine.transaction.internal.jta.JtaStatusHelper.getStatus处引发java.lang.NullPointerException的相关信息，请在本站查询。
