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"

           http://www.springframework.org/schema/tx/spring-tx.xsd">

        <property name="dataSource" ref="dataSource" />
        <property name="jpaVendorAdapter" ref="jpaVendorAdapter" />

    </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="dataSource" ref="dataSource" />

        <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>

我需要做些什么来解决这个错误？

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？
