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
