SSH框架整合之註冊登錄 .

上一篇介紹了三大框架的搭建，今天基於上一次的框架使用MVC模式完成註冊和登錄功能。

MVC模式：模型(Model),視圖(View)和控制Controller)。 MVC模式的目的就是實現Web系統的職能分工。 Model層實現系統中的業務邏輯，通常可以用JavaBean或EJB來實現。 View層用於與用戶的交互，通常用JSP來實現。 Controller層是Model與View之間溝通的橋樑，它可以分派用戶的請求並選擇恰當的視圖以用於顯示，同時它也可以解釋用戶的輸入並將它們映射爲模型層可執行的操作。

開發工具：1.MyEclipse6.5                2.mysql-5.0

 

1.創建數據庫 

這裏使用的是mysql5.0

數據庫名：mytest

表名：user

create database mytest;

use mytest;

create table user(

user_id int primary key auto_increment not null,

username varchar(50) not null,

password varchar(50) not null);

 最後注意要導入數據庫驅動jar包：mysql-connector-java-5.0.3-bin.jar

將mysql-connector-java-5.0.3-bin.jar放到WEB-INF的lib文件裏

2.導入Struts2.0所需要的jar包,刪除不需要的jar包(否則程序運行的時候會報錯)

導入6個jar包，刪除一個jar包

將以下Jar包直接複製到WEB-INF下的lib文件夾

 

刪除asm-2.2.3.jar

 

3. User.class和User.hbm.xml

新建Package：com.softeem.pojo

新建Class：User.class

新建XML：User.hbm.xml

User.class

package com.softeem.pojo;

public class User {
    private int user_id;
    private String username;
    private String password;
    public int getUser_id() {
        return user_id;
    }
    public void setUser_id(int user_id) {
        this.user_id = user_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;
    }

}

package com.softeem.pojo;

public class User {  
    private int user_id;  
    private String username;  
    private String password;  
    public int getUser_id() {  
        return user_id;  
    }  
    public void setUser_id(int user_id) {  
        this.user_id = user_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;  
    }  
  
}

 14.通過以上操作，SSH整合之登錄註冊已經完成

需要注意的是SSH框架的正確搭建和jar包的正確導入，對於新手這可能並不簡單。

框架搭建可以看上一篇文章   SSH框架整合之搭建

找不到jar包的直接下載項目吧    SSH整合之登陸註冊

稍後會放出SSH框架整合之增刪查改操作。
