Hibernate3.5.4---web application的xml和annotation环境搭建，整合struts2.1.8

说明：hibernate目前最高版本为3.6.0，struts的最高版本为2.2.1

在hibernate3.5版本以前，常用的包导入后，还需要：hibernate-commons-annotations.jar，hibernate-annotations.jar（反射时需要的包），ejb3-persistence.jar

而3.5及其以后的版本，需要导入：hibernate-jpa-2.0-api-1.0.0.Final.jar

目录结构：

 Action中代码：

 

package com.xie.struts.action;

 

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.hibernate.cfg.AnnotationConfiguration;

import org.hibernate.cfg.Configuration;

 

import com.opensymphony.xwork2.ActionSupport;

import com.xie.hibernate.modal.Student;

import com.xie.hibernate.modal.Teacher;

 

@SuppressWarnings("serial")

public class DbAction extends ActionSupport {

        public String addStudent(){

        Student s=new Student();

        s.setId(6);

        s.setName("cheng");

        s.setAge(12);

       

        Configuration cfg=new Configuration();

        SessionFactory sf=cfg.configure().buildSessionFactory();

        Session session=sf.openSession();

        session.beginTransaction();

        session.save(s);

        session.getTransaction().commit();

        session.close();

        System.out.println("ok");

        return SUCCESS;

       

        }

       

       public String addTeacher(){

        Teacher teacher=new Teacher();

            teacher.setId(6);

            teacher.setName("ma");

            teacher.setAge(16);

            teacher.setTitle("高级");

            Configuration cfg=new AnnotationConfiguration();

        SessionFactory sf=cfg.configure().buildSessionFactory();

        Session session=sf.openSession();

        session.beginTransaction();

        session.save(teacher);

        session.getTransaction().commit();

        session.close();

        System.out.println("ok");

        return SUCCESS;

       

        }
