淘忆项目之忘记密码界面的修正归纳
淘忆项目之忘记密码界面的修正归纳
忘记密码，这一部分目前简单处理一下，因为没有短信接口，所以就先用用户名作为唯一标识来处理，就是提交用户名和新密码，然后传到服务器端，服务器端通过更新密码来返回数据。
第一步：用photoshop来设计一下界面。
服务器端：
Com.elaine.forgetPwd.service写下如下代码：
package com.elaine.forgetPwd.service;
import java.util.List;
public interface ForgetPwdService {
public boolean isChangePwd(List
}
Com.elaine.forgetPwd.dao写下如下代码：
package com.elaine.forgetPwd.dao;
import java.sql.SQLException;
import java.util.List;
import com.elaine.forgetPwd.service.ForgetPwdService;
import com.elaine.jdbc.JdbcUtils;
public class ForgetPwdDao implements ForgetPwdService{
JdbcUtils jdbcUtils;
public ForgetPwdDao() {
// TODO Auto-generated constructor stub
jdbcUtils=new JdbcUtils();
}
@Override
public boolean isChangePwd(List
// TODO Auto-generated method stub
boolean flag=false;
try {
String sql="update userinfo set password=? where username=?"; //这是用于更新密码的语句
jdbcUtils.getConnection();
flag = jdbcUtils.updateByPreparedStatement(sql, params);
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return flag;
}
}
Com.elaine.forgetPwd.action写下如下代码：
package com.elaine.forgetPwd.action;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.elaine.forgetPwd.dao.ForgetPwdDao;
import com.elaine.forgetPwd.service.ForgetPwdService;
import com.elaine.tools.jsonTool;
public class ForgetPwdAction extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = 1L;
private ForgetPwdService service;
/**
* Constructor of the object.
*/
public ForgetPwdAction() {
super();
}
/**
* Destruction of the servlet.
*/
public void destroy() {
super.destroy(); // Just puts "destroy" string in log
// Put your code here
}
/**
* The doGet method of the servlet.
*
* This method is called when a form has its tag value method equals to get.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doPost(request, response);
}
/**
* The doPost method of the servlet.
*
* This method is called when a form has its tag value method equals to post.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
response.setContentType("text/html;charset=utf-8");
PrintWriter out = response.getWriter();
String username=request.getParameter("username");
String password=request.getParameter("password");
List
params.add(password);
params.add(username);
boolean flag=service.isChangePwd(params);
if(flag){
String addThingMsg="密码修改成功";
String addThingMsgJson=jsonTool.creataJsonString("msg", addThingMsg);
out.print(addThingMsgJson);
}else{
String addThingMsg="用户名错误";
String addThingMsgJson=jsonTool.creataJsonString("msg", addThingMsg);
out.print(addThingMsgJson);
}
out.flush();
out.close();
}
/**
* Initialization of the servlet.
*
* @throws ServletException if an error occurs
*/
public void init() throws ServletException {
// Put your code here
service=new ForgetPwdDao();
}
}
客户端传入两个数据，username和newPassword,然后解析返回的数据，显示。
首先是建立一个空的Activity，名为ForgetActivity.
第一步：将地址链接加入到UrlUtils,java中，
public static String getForgetPwdUrl() {
return URL + "/servlet/ForgetPwdAction";
}
第二步：将布局文件写好。

第三步：将功能实现，这部分还是很简单的。
