它在userService上执行getUser操作：

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();
    }
}

import java.util.List；
导入org.springframework.beans.factory.annotation.Autowired；
导入org.springframework.stereotype.Component；
@组成部分
公共类用户服务{
私有UserDAO UserDAO；
公共UserDAO getUserDao（）{
返回userDao；
}
@自动连线
公共void setUserDao（UserDAO UserDAO）{
this.userDao=userDao；
}
public void addUser（用户）{
getUserDao（）.insert（用户）；
}
公共用户getUser（int-id）{
返回getUserDao（）.load（id）；
}
公共列表fetchAllPersons（）{
返回getUserDao（）.selectAll（）；
}
}

它使用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;
    }

}

import java.util.List；
导入javax.persistence.EntityManager；
导入javax.persistence.PersistenceContext；
导入javax.persistence.Query；
导入org.springframework.stereotype.Repository；
导入org.springframework.transaction.annotation.Propagation；
导入org.springframework.transaction.annotation.Transactional；

公共类UserDAO{

}
公共列表selectAll（）{

@抑制警告（“未选中”）

}
}

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"

    <bean id="jpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">

        <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>  

com.mydomain.orm.User

我需要做什么来解决此错误

---

老实说，当这个问题解决后，我可能会得到一个JNDIEException。你认为是什么原因造成的

我会先尝试解决ClassNotFoundException。错误消息会让您更好地了解问题所在

---

为此，请检查hibernate核心库和hibernate entitymanager库的版本号。还要确保您的hibernate版本与jboss hibernate版本不冲突

可能有两个原因：

1:类路径中缺少包含

JNDIException

的适当hibernate库

2:重复的hibernate.jar之间存在版本冲突。如果试图在已经提供相同库但版本不同的容器（服务器）中部署应用程序，则可能会发生这种情况

---

当

JNDIException

类可以解决时，您的主要问题就会在错误消息中显现出来。

我将hibernate entitymanager的版本改写为与hibernate core相同。固定的

如果在pom.xml中使用hibernate core和hibernate entitymanager，则它们必须是同一版本。我试过了，解决了这个问题

 <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>4.1.9.Final</version>
    </dependency>


    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>4.1.9.Final</version>
    </dependency>

org.hibernate
冬眠核心
4.1.9.最终版本
org.hibernate
休眠实体管理器
4.1.9.最终版本

此处相同：与不同hibernate版本冲突有关的问题。将hibernate ehcache的版本改写为与hibernate core相同，以修复使用eh cache配置二级缓存时发生的相同问题。

 <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>4.1.9.Final</version>
