Hibernate3.3以上版本报Exception in thread "main" java.lang.NoClassDefFoundError: javax/persistence/Cacheable异常

Exception in thread "main" java.lang.NoClassDefFoundError: javax/persistence/Cacheable

我用annotations做hibernate操作时报这个错误请问是什么原因：
Exception in thread "main" java.lang.NoClassDefFoundError: javax/persistence/Cacheable
 at org.hibernate.cfg.AnnotationBinder.determineCacheSettings(AnnotationBinder.java:953)
 at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:596)

环境，hibernate3.6 annotation3.4
三个java类
Teacher.java

package com.unis.hibernate.model;

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table
public class Teacher {

	private int id;
	private String name;
	private String title;

	//一般加在方法上，还有加在属性上的，但是不能保证属性和方法不一致所以都加在方法上
	@Id
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getTitle() {
		return title;
	}
	public void setTitle(String title) {
		this.title = title;
	}

}

  package com.unis.hibernate.main;

import org.hibernate.Transaction;
import org.hibernate.classic.Session;

import com.unis.hibernate.model.Teacher;
import com.unis.hibernate.util.HibernateUtil;

public class TeacherMain {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		TeacherMain stu = new TeacherMain();
		 Teacher teacher  = new Teacher();
		 teacher.setName("likai");
		 teacher.setTitle("Hibernate");
		 stu.addStudent(teacher);
	}

	public void addStudent(Teacher teacher){
		Session session = null;
		Transaction ts = null;
		try{
			session = HibernateUtil.getSessionFactory().openSession();
			ts = session.beginTransaction();
			session.save(teacher);
			ts.commit();

		}finally{
			if(session != null){
				session.close();}
			}
	}
}

package com.unis.hibernate.util;


import org.hibernate.Session;
import org.hibernate.SessionFactory; 
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.cfg.Configuration;


public final class HibernateUtil { 

	private static SessionFactory sfc; 

	private HibernateUtil(){

	}
	static{
		Configuration cfg = new AnnotationConfiguration();
		cfg.configure();
		sfc = cfg.buildSessionFactory();
	}

	public static SessionFactory getSessionFactory(){
		return sfc;
	} 
	public static Session getSession(){ 
		return sfc.openSession();
	}

}

hibernate.cfg.xml中的mapping
<mapping class="com.unis.hibernate.model.Teacher"/>

 

推荐答案

javax.persistence.Cacheable 是 JPA 2.0 规范中的东西！

需要加入hibernate-distribution-3.6.0-Final/lib/jpa目录下的hibernate-jpa-2.0-api-1.0.0.Final.jar加到web工程的lib包下
