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;

        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");
