6、Spring+Struts2+MyBatis（mybatis有代理）整合增删改查

1、创建如下的oracle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

3、在项目的WebRoot下的WEB-INF下的lib下添加如下jar文件

aopalliance.jar
aspectjweaver.jar
cglib-nodep-2.1_3.jar
commons-fileupload-1.2.1.jar
commons-io-1.3.2.jar
commons-logging-1.0.4.jar
freemarker-2.3.15.jar

4、在src下的com.bean包下创建UserInfo.java

 package com.bean;

 public class UserInfo {

     private Integer id;

     private String name;

     private String password;

     private String telephone;

     private String isadmin;

     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 + "]";

     }

 }

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

16、在WebRoot下创建success.jsp

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

 <%@taglib uri="/struts-tags" prefix="s"%>

 <%

 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>

    <h1>操作成功</h1>

    <s:if test="user.name eq 'holly'">

       holly你来啦?

    </s:if>

    <s:else>

       我不认识你?你是谁?

    </s:else>

   </body>

 </html>

success.jsp

17、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

18、运行

<%@ 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"> </head> <body> <center> <fieldset style="width:400px;"> <legend>注册</legend> <form action="registerUser.action" method="post"> <table> <tr> <td>用户名:</td> <td><input type="text" name="user.name"/></td> </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="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>
