7、Spring+Struts2+MyBaits(无映射接口实现类)

1、创建userinfo.sql数据库脚本

  create table userinfo

 (id number(4),

 name varchar2(50),

 password varchar2(20),

 telephone varchar2(15),

 isadmin varchar2(5));

  --4.2 用户表序列

  create sequence seq_userinfo;

  alter table userinfo add constraint pk_userinfo_id primary key(id);

  insert into userinfo values(seq_userinfo.nextval,'holly','','134518024

 ','是');

  commit;

userinfo.sql

2、创建如下项目结构

7、Spring+Struts2+MyBaits(无映射接口实现类)

3、在src的com.bean包下创建UserInfo.java

 package com.bean;

 /**

  * 用户信息表

  * @author Holly老师

  *

  */

 public class UserInfo {

     private Integer id;//编号

     private String name; //姓名

     private String password; //密码

     private String telephone; //电话

     private String isadmin; //是否是管理员

     public UserInfo() {

     }

     public UserInfo(Integer id, String name, String password, String telephone,

             String isadmin) {

         this.id = id;

         this.name = name;

         this.password = password;

         this.telephone = telephone;

         this.isadmin = isadmin;

     }

     public Integer getId() {

         return id;

     }

     public void setId(Integer id) {

         this.id = id;

     }

     public String getName() {

         return name;

     }

     public void setName(String name) {

         this.name = name;

     }

     public String getPassword() {

         return password;

     }

     public void setPassword(String password) {

         this.password = password;

     }

     public String getTelephone() {

         return telephone;

     }

     public void setTelephone(String telephone) {

         this.telephone = telephone;

     }

     public String getIsadmin() {

         return isadmin;

     }

     public void setIsadmin(String isadmin) {

         this.isadmin = isadmin;

     }

     @Override

     public String toString() {

         return "UserInfo [id=" + id + ", isadmin=" + isadmin + ", name=" + name

                 + ", password=" + password + ", telephone=" + telephone + "]";

     }

 }

UserInfo.java

4、在src的com.dao包下创建UserInfoDao.java

 package com.dao;

 import java.util.List;

 import com.bean.UserInfo;

 /**

  * mybatis映射文件的dao接口

  * @author Holly老师

  *

  */

 public interface UserInfoDao {

     /**

      * 1.根据对象去查询对象

      * @return

      */

     public UserInfo findUser(UserInfo userinfo);

     /**

      * 2.查询所有

      * @return

      */

     public List<UserInfo> findAll();

     /**

      * 3.根据id查询

      */

     public UserInfo findById(int id);

     /**

      * 4.保存对象

      * @param userinfo

      */

     public void saveObj(UserInfo userinfo);

     /**

      * 5.修改对象

      */

     public void updateObj(UserInfo userinfo);

     /**

      * 6.删除对象

      * @param id

      */

     public void deleteObj(int id);

 }

UserInfoDao.java

5、在src的com.dao包下创建UserInfoDao.xml

 <?xml version="1.0" encoding="UTF-8"?>

 <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >

 <mapper namespace="com.dao.UserInfoDao">

         <result property="telephone" column="telephone"/>

         <result property="isadmin" column="isadmin"/>

     </resultMap>

     -->

     <!--1.根据对象查询对象 -->

   <select id="findUser" parameterType="userinfo" resultType="userinfo">

      select * from userinfo where name=#{name} and password=#{password}

   </select>

   <!-- 2.查询所有 -->

     select * from userinfo

   </select>

   <!-- 3.根据id查询 -->

   <select id="findById" parameterType="int" resultType="userinfo">

      select * from userinfo where id=#{id}

   </select>

   <!-- 4.根据id删除 -->

   <delete id="deleteObj" parameterType="int">

      delete from userinfo where id=#{id}

   </delete>

   <!-- 5.修改 -->

   <update id="updateObj" parameterType="userinfo">

     update userinfo set name=#{name},password=#{password},telephone=#{telephone},isadmin=#{isadmin} where id=#{id}

   </update>

   <!-- 6.保存 -->

   <insert id="saveObj" parameterType="userinfo">

      insert into userinfo values(seq_userinfo.nextval,#{name},#{password},#{telephone},#{isadmin})

   </insert>

 </mapper>

UserInfoDao.xml

6、在src下创建mybatis-config.xml

 <?xml version="1.0" encoding="UTF-8"?>

   <!-- mybatis映射文件的别名配置 -->

   <typeAliases>

     <typeAlias type="com.bean.UserInfo" alias="userinfo"/>

   </typeAliases>

     //action中引用实体类和页面上一一对应

     //表单name属性值里的对象

     private UserInfo user;

     /*注入dao*/

     private UserInfoDao dao;

     /**

      * 1.登录

      * @return

     public String login(){

             System.out.println("action:"+user.getName());

             UserInfo userinfo=dao.findUser(user);

               </tr>

               <tr>

                    <td>密码:</td>

                    <td><input type="password" name="user.password"/></td>

                </tr>

               <tr>

                    <td>电话号码:</td>

                    <td><input type="text" name="user.telephone"/></td>

                </tr>

               <tr>

                    <td>是否是管理员:</td>

                    <td>

                    <input type="radio" name="user.isadmin" value="否" checked="checked"/>

                    </td>

                </tr>

               <tr>

                    <td><input type="submit" value="提交"/></td>

                </tr>

             </table>

         </form>

       </fieldset>

     </center>

   </body>

 </html>

14、在WebRoot下创建update.jsp

 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

 <%

 String path = request.getContextPath();

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

 %>

 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

 <html>

   <head>

     <base href="<%=basePath%>">

     <title>修改页面</title>

     <meta http-equiv="pragma" content="no-cache">

     <meta http-equiv="cache-control" content="no-cache">

     <meta http-equiv="expires" content="0">

     <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

     <meta http-equiv="description" content="This is my page">

   </head>

   <body>

     <center>

       <fieldset style="width:400px;">

         <legend>修改页面</legend>

         <form action="updateObj.action" method="post">

             <table>

               <tr>

                   <td>用户名:</td>

                   <td><input type="text" name="user.name" value="${uv.name}"/></td>

               </tr>

               <tr>

                    <td>密码:</td>

                    <td><input type="password" name="user.password" value="${uv.password}"/></td>

                </tr>

               <tr>

                    <td>电话号码:</td>

                    <td><input type="text" name="user.telephone" value="${uv.telephone}"/></td>

                </tr>

               <tr>

                    <td>是否是管理员:</td>

                    <td>

                    <input type="radio" name="user.isadmin" value="是">

                    <input type="radio" name="user.isadmin" value="否" checked="checked"/>

                    </td>

                </tr>

               <tr>

                    <td><input type="submit" value="提交"/></td>

                    <td><input type="reset" value="重置"/></td>

                </tr>

             </table>

         </form>

       </fieldset>

     </center>

   </body>

 </html>

update.jsp

15、在WebRoot下创建error.jsp

 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

 <%

 String path = request.getContextPath();

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

 %>

 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

 <html>

   <head>

     <base href="<%=basePath%>">

     <title>My JSP 'index.jsp' starting page</title>

     <meta http-equiv="pragma" content="no-cache">

     <meta http-equiv="cache-control" content="no-cache">

     <meta http-equiv="expires" content="0">

     <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

     <meta http-equiv="description" content="This is my page">

     <!--

     <link rel="stylesheet" type="text/css" href="styles.css">

     -->

   </head>

   <body>

       操作失败!

   </body>

 </html>

error.jsp
