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 basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
