springmvc springJDBC 簡單實訓銀行帳戶管理系統css

1.簡單介紹一下，在校時每週結束都會有一次學習總結，簡稱「實訓」，此次實訓內容是spring，由於是最近熱門框架，我就先從基礎方面開始練習，一路填坑，有點不容易。這是我第一次寫文章，可能不太完善，但願多多包涵。喜歡的同窗能夠關注一會兒。html

項目建完大概是這樣，看一下：java

——————————————————————————————————————————————————————————————mysql

2.項目搭建需求：
web

myEclipse + mysql + jdk1.6 + (spring 3.0 core Libraries+spring 3.0 AOP Libraries+spring 3.0 Web Libraries+spring 3.0+persistence JDBC Libraries+spring 3.0 persistence Core Libraries) + mysql5.17.jarspring

大體是這些，如仍是不明白能夠隨時聯繫我：1763907618+備註（博客園）sql

——————————————————————————————————————————————————————————————數據庫

3.數據庫搭建：session

創建數據庫名字 bankmvc

創建表格trade 和 user 字段以下：

————————————————————————————————————————————————————————————————————————————————————

4.代碼及功能的實現：

先看主要項目結構：

好了，不廢話開始咱們的第一步。

new--------web project-------輸入name-------finish

右鍵單擊項目 ---------MyEclipse-----------Add spring Capabilities 如圖：

接下來選擇spring3.0 選擇所須要的jar包；如圖：-------選擇好後------finish

將applicationContext.xml拖入到webroot/web-inf內，如圖：

同時將mysql驅動jar放入lib內。！！！！！

在src內創建四個包，我就不一一打了，如圖：

嗯，如今基本準備好了，就先擼一個登陸部分，直接上代碼吧：

在applicationContext,xml里加代碼：

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

可能會有錯誤提示，別急，一步步來；

在web.xml裏修改，如：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

</init-param>
</filter>

<filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<welcome-file-list>
   <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
  
<servlet> 
   <servlet-name>Dispatcher</servlet-name>
     <servlet-class>
         org.springframework.web.servlet.DispatcherServlet
   </servlet-class>
   <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </init-param>
</servlet>
  
<servlet-mapping>
    <servlet-name>Dispatcher</servlet-name>
    <url-pattern>*.do</url-pattern>
</servlet-mapping>
  
</web-app>

在index.jsp裏修改如：

<%@ 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>登陸</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>    
        <form action="userLogin.do" method="post" >
            <input type="text" name="username"  placeholder="登陸|帳號" /><br />            
            <input type="password" name="password" placeholder="輸入密碼" /><br />        
            <input type="submit" value="登  錄" /><br/>
            <input type="button" name="button" id="button" value="註冊" onClick="location.href='userAdd.jsp'" >         
        </form>  
  </body>
</html>

創建main.jsp裏面添加幾句話就行，一會登陸成功跳轉的頁面。

創建userAdd.jsp,這是註冊頁面，順手寫了吧。

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

    </div>
    </form>
  </body>
</html>

在com.pojo裏創建User.java

package com.pojo;

public class User {
    public static final int PAGE_SIZE=10;
    private int id;
    private String username;
    private String password;
    private String userflag;
    private int userage;
    private String idcard;
    private String tel;
    private String city;
    private String useradd;
    private String sex;
    
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    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;
    }
    public String getUserflag() {
        return userflag;
    }
    public void setUserflag(String userflag) {
        this.userflag = userflag;
    }
    public int getUserage() {
        return userage;
    }
    public void setUserage(int userage) {
        this.userage = userage;
    }
    public String getIdcard() {
        return idcard;
    }
    public void setIdcard(String idcard) {
        this.idcard = idcard;
    }
    public String getTel() {
        return tel;
    }
    public void setTel(String tel) {
        this.tel = tel;
    }
    public String getCity() {
        return city;
    }
    public void setCity(String city) {
        this.city = city;
    }
    public String getUseradd() {
        return useradd;
    }
    public void setUseradd(String useradd) {
        this.useradd = useradd;
    }
    public String getSex() {
        return sex;
    }
    public void setSex(String sex) {
        this.sex = sex;
    }
    public static int getPageSize() {
        return PAGE_SIZE;
    }
}

上面那個至關好理解，也容易自動生成，不詳細說明了。

在com.dao裏創建UserDao.java代碼以下：

package com.dao;

import java.util.List;

import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.support.JdbcDaoSupport;

import com.pojo.User;

public class UserDao extends JdbcDaoSupport {
    
    //用戶----  用戶登錄
    @SuppressWarnings("unchecked")
    public List userLogin(User user){
        JdbcTemplate jt=new JdbcTemplate(getDataSource());
        String sql="select * from user where username='"+user.getUsername()+"' and password='"+user.getPassword()+"'";
        List rows=jt.queryForList(sql);
        return rows;
    }
    //用戶----  用戶註冊
    public int userAdd(User user){
        JdbcTemplate jt=new JdbcTemplate(getDataSource());
        String sql = "insert  into user (username, password, userflag,userage,idcard,tel,city,useradd,sex) " +
                "value('"+user.getUsername()+"','"+user.getPassword()+"','"+user.getUserflag()+"','"+user.getUserage()+"','"+user.getIdcard()+"','"+user.getTel()+"','"+user.getCity()+"','"+user.getUseradd()+"','"+user.getSex()+"')";
        int n=jt.update(sql);
        return n;
        
    }


}

上面這個主要涉及到數據庫一些內容，仍是老樣子不懂諮詢我。

在com.service裏創建UserService.java.如：

package com.service;

import java.util.List;

import com.dao.UserDao;
import com.pojo.User;

public class UserService {
    UserDao userDao;
    public UserDao getUserDao() {
        return userDao;
    }
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }
    
    //用戶----  用戶登錄
    @SuppressWarnings("unchecked")
    public List userLogin(User user){
        return userDao.userLogin(user);
    }
    //用戶----  用戶註冊
    public int userAdd(User user){
        return userDao.userAdd(user);
        
    }
    
}

在com.controller裏建立UserLoginAction.java 登陸

package com.controller;

import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;

import com.pojo.User;
import com.service.UserService;

@SuppressWarnings("deprecation")
public class UserLoginAction extends SimpleFormController {
    public String success_view;
    public String shibai_view;
    public String getShibai_view() {
        return shibai_view;
    }
    public void setShibai_view(String shibaiView) {
        shibai_view = shibaiView;
    }
    public UserService userService;
    public String getSuccess_view() {
        return success_view;
    }
    public void setSuccess_view(String successView) {
        success_view = successView;
    }
    public UserService getUserService() {
        return userService;
    }
    public void setUserService(UserService userService) {
        this.userService = userService;
    }
    @SuppressWarnings("unchecked")
    protected ModelAndView onSubmit(HttpServletRequest request,HttpServletResponse response,Object cmd,BindException ex)throws Exception{
        User user=(User)cmd;
        List list=userService.userLogin(user);
        String username=user.getUsername();

        HttpSession session=request.getSession();
        session.setAttribute("user", list);
        session.setAttribute("username", username);
        if(list==null||list.size()<1){
            return new ModelAndView(this.getShibai_view());
        }else {
            return new ModelAndView(this.getSuccess_view());
        }
        
    }


}

在com.controller裏建立UserAddAction.java 註冊

package com.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;

import com.pojo.User;
import com.service.UserService;

@SuppressWarnings("deprecation")
public class UserAddAction extends SimpleFormController {
    public String success_view;
    public UserService userService;
    public String getSuccess_view() {
        return success_view;
    }
    public void setSuccess_view(String successView) {
        success_view = successView;
    }
    public UserService getUserService() {
        return userService;
    }
    public void setUserService(UserService userService) {
        this.userService = userService;
    }
    protected ModelAndView onSubmit(HttpServletRequest request,HttpServletResponse response,Object cmd,BindException ex)throws Exception{
        User user=(User)cmd;
        int n=userService.userAdd(user);
        request.setAttribute("user", user.getUsername());
        
        if(n>0){
            request.setAttribute("userAddMes", "註冊成功");
        }else{
            request.setAttribute("userAddMes", "註冊失敗");
        }
        return new ModelAndView(this.getSuccess_view());
    }

}
