Hibernate和jsp做数据库单表的增删改查

虽然很基础，但是我转牛角尖了~~~~这是几个文件

1.最重要的。Java文件

package com.chinasofti.hibb.struts;


import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import com.chinasofit.hibb.entity.Test;
import com.opensymphony.xwork2.ActionSupport;



@SuppressWarnings("serial")
public class HibbTest extends ActionSupport {
    private Test test;
    private int id;

    public Test getTest() {
        return test;
    }
    public void setTest(Test test) {
        this.test = test;
    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public Session session(){
    Configuration config = new Configuration().configure();
    SessionFactory factory = config.buildSessionFactory();
    Session session = factory.openSession();
    return session;
    }
    //1.查找
    public String testchazhao(){
        //int id= (Integer) session.getAttribute("id");可以直接获取页面上输入的ID，不用再获取什么的；
        Session session=session();
        test = (Test) session.get(Test.class, id);
        session.close();
        return "testchazhao";
    }
    //2.添加
    public String Zhuce(){
     //   Session session1 = HibernateSessionFactory.getSession();
        Session session=session();
        Transaction tes = session.beginTransaction();        
        session.save(test);
        //id=test.getId();
        tes.commit();  //提交事务
    //    tes.rollback();//事务回滚
        session.close(); //关闭Session对象
        return "zhuce";
    }
   //3.更改
    public String update(){
        //1.查找出id
        Session session =session();
        Transaction tx = session.beginTransaction();
        test = (Test)session.get(Test.class, id);
        tx.commit();
        session.close();
        //2.更改
        test.setName("王二小");
        Session session1 = session();
        Transaction tx1 = session1.beginTransaction();
        session1.update(test);
        tx1.commit();
        session1.close();
        return "genggai";
    }
    //4.删除，根据id 
    public String delete(){
        Session session =session();
        Transaction tx = session.beginTransaction();
        test = (Test)session.get(Test.class, id);
        session.delete(test);
        tx.commit();
        session.close();
        return "shanchu";
    }
}

    
    
    
    
    
    
    

2.就是test路径

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>

    <package name="Ttest" namespace="/" extends="struts-default">
        <!-- 查找 -->
        <action name="Hibb" class="com.chinasofti.hibb.struts.HibbTestId" >
            <result name="hibbtestid"   type="dispatcher">/testchaid.jsp</result>
        </action>            
        <action name="HibbTest" class="com.chinasofti.hibb.struts.HibbTest" method="testchazhao">
            <result name="testchazhao" type="dispatcher">/testchazhao.jsp</result>
        </action>    
        <!-- 增加 -->
        <action name="Zhuce" class="com.chinasofti.hibb.struts.HibbTestzhuceOk" >
            <result name="zhuceok" type="dispatcher">/testzhuce.jsp</result>
        </action>    
        <action name="ZhuceOk" class="com.chinasofti.hibb.struts.HibbTest" method="Zhuce">
            <result name="zhuce" type="dispatcher">/testchazhao.jsp</result>
        </action>
        <!-- 修改 -->
        <action name="Gengai" class="com.chinasofti.hibb.struts.HibbTestgengai" >
        <result name="hibbtestgenggai" type="dispatcher">/testgenggaiid.jsp</result>
        </action>    
        <action name="GengaiOk" class="com.chinasofti.hibb.struts.HibbTest" method="update">
        <result name="genggai" type="dispatcher">/testchazhao.jsp</result>
        </action>
        
        <!-- 删除 -->
        <action name="Shanchu" class="com.chinasofti.hibb.struts.HibbTestshanchu" >
        <result name="hibbtestshanchu" type="dispatcher">/testshanchu.jsp</result>
        </action>    
        <action name="ShanchuOk" class="com.chinasofti.hibb.struts.HibbTest" method="delete">
        <result name="shanchu" type="dispatcher">/testchazhao.jsp</result>
        </action>
        
        
        
            
   </package>
</struts>    

3.增删改查访问的路径都是通过ID，所以需要几个可以跳转ID的JSP和action。

package com.chinasofti.hibb.struts;

public class HibbTestgengai {
    public String execute(){
          return "hibbtestgenggai";
        }
}

package com.chinasofti.hibb.struts;

public class HibbTestzhuceOk {
    public String execute(){
          return "zhuceok";
        }

}

package com.chinasofti.hibb.struts;

public class HibbTestshanchu {
    public String execute(){
          return "hibbtestshanchu";
        }
}

package com.chinasofti.hibb.struts;

public class HibbTestId {
    public String execute(){
      return "hibbtestid";
    }
    
}

4.基本上在Struts里，最后跳转的都是查找JSP界面，这样可以知道自己到底对数据库做了什么

String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
