When my Spring controller handles the connection:
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;
}
It does a getUser on the userService:
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();
}
}
Which uses the userDao to find the entity:
它使用 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;
}
}
I have the following spring-config.xml in /src/main/resources:
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"

<property name="url" value="jdbc:postgresql://localhost:5432/mydb" />
<property name="username" value="my_user" />
<property name="password" value="" />
</bean>
</beans>
And last but not least the following /src/main/resources/persistence.xml:
最后但并非最不重要的以下/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>
What do I need to do to resolve this error?
我需要做什么来解决这个错误？
Honestly though, when this is resolved, I'm probably just going to get a JndiException. What do you think might also be causing that?
老实说，当这个问题得到解决时，我可能只会得到一个 JndiException。你认为可能是什么原因造成的？

I overwrote the version of hibernate-entitymanager to be the same as hibernate-core. fixed.
我将 hibernate-entitymanager 的版本覆盖为与 hibernate-core 相同。固定的。
回答by Till
I would try to resolve the ClassNotFoundException first. The error message should give you a better idea about what's wrong.
我会先尝试解决 ClassNotFoundException。错误消息应该让您更好地了解问题所在。
In order to do that check the version numbers of your hibernate-core lib and your hibernate-entitymanager lib. Also make sure your hibernate version is not conflicting with the jboss hibernate version.
为此，请检查您的 hibernate-core 库和 hibernate-entitymanager 库的版本号。还要确保您的休眠版本与 jboss 休眠版本不冲突。
回答by Diversity
There could be 2 reasons:
可能有2个原因：
1: an appropriate hibernate lib which contains the JNDIExceptionis missing within the classpath
1：一个适当的休眠库，其中包含JNDIException类路径中缺少的
2: There is a version conflict between duplicate hibernate.jars. This can happen if one tries to deploy an application within a JEEContainer (server) which already provides the same library but with a different version.
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，就会发生这种情况。
When the JNDIExceptionclass can be resolved than your main problem becomes apparent within the error message.
当JNDIException该类可以解决时，您的主要问题就会在错误消息中变得明显。

?f you are using hibernate-core & hibernate-entitymanager in your pom.xml, They must mu same version. I tried this and solved.
?如果您在 pom.xml 中使用 hibernate-core 和 hibernate-entitymanager，它们必须是相同的版本。我试过这个并解决了。
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.1.9.Final</version>
