Hibernate Annotation 遇到问题
数据库结构

 CREATE TABLE `person` (                           `id` int(4) default NULL,                       `name` varchar(20) default '',                  `password` varchar(20) default ''             ) ENGINE=InnoDB DEFAULT CHARSET=latin1

映射表的java类

import javax.persistence.*;@Entity@Table(name="person")public class User implements java.io.Serializable {@Id@GeneratedValue(strategy = GenerationType.AUTO)private Integer id;private String name;private String password;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public User() {    }}

HibernateUtils

import org.apache.log4j.Logger;import org.hibernate.SessionFactory;import org.hibernate.cfg.AnnotationConfiguration;import org.hibernate.cfg.Configuration;import org.hibernate.Session;public class HibernateUtils {private static final Logger logger = Logger.getLogger(HibernateUtils.class);private static final SessionFactory sessionFactory;private static Configuration configuration;private static final String resource; static {try {resource = "hibernate.cfg.xml";   sessionFactory = new AnnotationConfiguration().configure(resource).buildSessionFactory();  //sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory(); //configuration = new Configuration();          //  sessionFactory = configuration.configure("hibernate.cfg.xml").buildSessionFactory();} catch (Exception e) {logger.error(e.getMessage());throw new ExceptionInInitializerError(e);}}public static Session getSession() {return sessionFactory.openSession();}}

hibernate.cfg.xml配置内容:

<?xml version='1.0' encoding='UTF-8'?><!DOCTYPE hibernate-configuration PUBLIC          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"><!-- Generated by MyEclipse Hibernate Tools.                   --><hibernate-configuration>    <session-factory>        <property name="connection.username">root</property>        <property name="connection.url">jdbc:mysql://localhost:3306/test</property>        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>        <property name="connection.password">123456</property>        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>        <property name="show_sql">true</property>        <!-- 设置entity bean -->        <!--<mapping resource="t_user.hbm.xml"/>-->        <mapping name="code">import org.hibernate.Session;import org.hibernate.Transaction;public class test {public static void main(String[] args) {// 将持久化的物件User user = new User();user.setId(3);user.setName("ady");user.setPassword("123456");Session session = HibernateUtils.getSession();Transaction tx = session.beginTransaction();session.saveOrUpdate(user);tx.commit();}}

运行出现一下异常

Exception in thread "main" java.lang.NoSuchMethodError: org.hibernate.util.ReflectHelper.classForName(Ljava/lang/String;Ljava/lang/Class;)Ljava/lang/Class;at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:752)at HibernateUtils.<clinit>(HibernateUtils.java:22)at test.main(test.java:17)

这是什么错误啊？有谁遇到过吗？苦恼了好几个小时了。。。
