实现用户通过数据库验证登录需求,采用Myeclipse+Tomcat 6.0+Mysql 5.0+JDK 1.6
2.数据库表
开发所用是Mysql数据库,只建立单张用户表T_USER,表结构如下:
字段名称 | 数据类型 | 字段描述 |
ID | int | 用户编号 |
USERNAME | VARCHAR | 用户名 |
PASSWORD | VARCHAR | 用户登录密码 |
CREATE TABLE `t_user` (
`ID` int(11) NOT NULL auto_increment,
`USERNAME` varchar(255) default NULL,
`PASSWORD` varchar(255) default NULL,
PRIMARY KEY (`ID`)
);
3.构建源代码目录
4.用到的jar包(见附件Archive.rar)
5.各项Xml配置文件详解
(1)web.xml文件(Tomcat使用)
服务器根据配置内容初始化spring框架,springmvc框架和log4j日志框架

(6)sqlMapConfig.xml(Ibatis框架配置文件)
该文件主要负责指定sql映射文件,即与model层对象对应的映射文件

6.Java代码编写
根据包目录,可以看出分成model层,dao层,service层和web层,另外附加test层,用于java环境测试
(1)model层(User.java+User.xml)
User.java代码
- <STRONG><SPAN style="FONT-SIZE: 18px">package com.archie.model;
- public class User {
- private int id;
- private String username;
- private String password;
- public User(){
- }
- public User(int id){
- this.id = id;
- }
- public User(int id, String username){
- this.id = id;
- this.username = username;
- }
- public User(String username, String password) {
- this.username = username;
- this.password = password;
- }
- public User(int id, String username, String password){
- this.id = id;
- this.username = username;
- this.password = password;
- }
- 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;
- }
- }
- </SPAN></STRONG>
package com.archie.model;
public class User {
private int id;
private String username;
private String password;
public User(){
}
public User(int id){
this.id = id;
}
public User(int id, String username){
this.id = id;
this.username = username;
}
public User(String username, String password) {
this.username = username;
this.password = password;
}
public User(int id, String username, String password){
this.id = id;
this.username = username;
this.password = password;
}
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;
}
}
User.xml代码(model层对象的sql映射文件,被dao层调用,本质是sql语句集合,所有相关的sql均于此)
