一个简单的注册框架

myEclipse 新建一个web project

MySQL新建一个 user表一个简单的注册框架

首先建立首页面 regsuccess.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>注册成功</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>
<br>
<div align="center" style="color: red;font-size: 100px;">
${user.username }注册成功！
</div>
</body>
</html>

然后是成功页面success.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>登陆成功</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>
<br>
<div align="center" style="color: red;font-size: 100px;">
${user.username }登录成功！
</div>
</body>
</html>

接下来是跳转xml文件 xitongguanli.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

<constant name="struts.configuration.xml.reload" value="true"/>

<package name="xitongguanli" namespace="/" extends="base">

<action name="Login" class="LoginAction">
<result name="success">xitongguanli/success.jsp</result>
<result name="error">xitongguanli/error.jsp</result>
</action>
<action name="Register" class="RegisterAction">
<result name="success">xitongguanli/regsuccess.jsp</result>
</action>
</package>
</struts>

就下来以此是RegisterAction.java，IUserDao.java，User.java，IUserService.java，user.xml，xitongguanli.xml，jdbc.properties

1. RegisterAction.java

package com.yy.xitongguanli.action;

import com.opensymphony.xwork2.ActionSupport;
import com.yy.xitongguanli.po.User;
import com.yy.xitongguanli.service.IUserService;

public class RegisterAction extends ActionSupport {
private String username;
private String password;

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

private IUserService userService;
public void setUserService(IUserService userService) {
this.userService = userService;
}

@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
User user = new User();
user.setUsername(username);
user.setPassword(password);
userService.saveUser(user);
return SUCCESS;
}
}

2.IUserDao.java

package com.yy.xitongguanli.dao;

import java.util.Map;

import com.yy.xitongguanli.po.User;

public interface IUserDao {
public User getUserByMap(Map<String, Object> map);
public int saveUser(User user);

}
3.User.java

package com.yy.xitongguanli.po;

public class User {
private int userId;
private String username;
private int sex;
private String password;
private int flag;
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public int getSex() {
return sex;
}
public void setSex(int sex) {
this.sex = sex;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public int getFlag() {
return flag;
}
public void setFlag(int flag) {
this.flag = flag;
}
}

4.IUserService.java

package com.yy.xitongguanli.service;

import java.util.Map;

import com.yy.xitongguanli.po.User;

public interface IUserService {
public User getUserByMap(Map<String, Object> map);
public int saveUser(User user);
}

5.user.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.yy.xitongguanli.dao.IUserDao">

<select id="getUserByMap" resultType="com.yy.xitongguanli.po.User">
SELECT * FROM user where 1 = 1
<if test="username != null ">
and username = #{username}
</if>
<if test="password != null ">
and password = #{password}
</if>
</select>
<insert id="saveUser" parameterType="com.yy.xitongguanli.po.User">
insert user(username,password) values(#{username},#{password})
</insert>
</mapper>

6.xitongguanli.xml
