public class Stu implements java.io.Serializable {

 

    // Fields

 

    private Integeruserid;

    private Stringpwd;

 

    // Constructors

    public void setPwd(String pwd) {

       this.pwd = pwd;

    }

 

}

 

从页面来的数据传到UserManagerAction，对象stu得到属性值

UserManagerAction.java

package com.ibm.action;

 

import com.ibm.pojo.Stu;

import com.ibm.service.IUserOperService;

 

public class UserManagerAction {

    //定义一个stu对象

    private Stustu;

    //定义一个service层的接口

    private IUserOperServiceservice;

   

    public String  execute() {

        //调用service层

       service.addUser(stu);

       System.out.println(stu.getUsername());

       return"success";

    }

   

    public Stu getStu() {

       returnstu;

    }

   //set方法为stu对象设置值

    public void setStu(Stu stu) {

       this.stu = stu;

    }

    public IUserOperService getService() {

       returnservice;

    }

    //action层通过Set方法注入接口IUserOperService

    public void setService(IUserOperService service) {

       this.service = service;

    }

}

 

//定义service接口

IuserOperService.java

package com.ibm.service;

 

import com.ibm.pojo.Stu;

 

public interface IUserOperService {

   

    public void addUser(Stu stu);

}

 

//接口service的实现类

UserOperService.java

package com.ibm.service.iservice;

 

import com.ibm.dao.IUserOperDAO;

import com.ibm.pojo.Stu;

import com.ibm.service.IUserOperService;

 

public class UserOperService implements IUserOperService{

    //定义用户接口userOperDAO

    IUserOperDAO userOperDAO;

   

    public void addUser(Stu stu) {

       // TODO Auto-generated method stub

        //调用接口中实现类的add方法

       userOperDAO.add(stu);

    }

 

    //service层通过Set方法注入接口userOperDAO

    public void setUserOperDAO(IUserOperDAO userOperDAO) {

       this.userOperDAO = userOperDAO;

    }

}

 

定义功能接口IUserOperDAO

IUserOperDAO.java

package com.ibm.dao;

 

import com.ibm.pojo.Stu;

 

public interface IUserOperDAO {

    public void add(Stu stu);

}

 

功能接口IuserOperDAO实现类

UserOperDAO.java

package com.ibm.dao.idao;

import org.hibernate.Transaction;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

 

import com.ibm.dao.ILogOperDAO;

import com.ibm.dao.IUserOperDAO;

import com.ibm.factory.HibernateSessionFactory;

import com.ibm.pojo.Logtb;

import com.ibm.pojo.Stu;

 

/**

//  public void add(Stu stu) {

////       } catch (Exception e) {

////          e.printStackTrace();

////       }

//  }

//

//}

  //继承Spring中的HibernateDaoSupport类，并实现功能接口IUserOperDAO

  public class UserOperDAO extends HibernateDaoSupportimplements IUserOperDAO{

 

       public void add(Stu stu){

//使用Spring自带的事务管理器来管理sessionFactory(配置文件在Spring中的applicationContext-tran.xml)，得到getHibernateTemplate()方法，然后调用它的save方法保存数据

           this.getHibernateTemplate().save(stu);

       }

  }
