这是我用SSH框架开发的一个简单的注册登录系统，包括js校验，css前端样式呈现等等；下面来详细介绍系统的开发流程：
软硬件平台
软件环境
1.win7 32为操作系统；
2.MyEclipse10.5；
3.Tomcat7.0；
4.Java EE6；
5.jdk1.7；
6.MySQL 5.6；
硬件环境
CPU：Intel Pentium Dual-Core T4500 2.3GHZ处理器；
内存：2G；
项目所依赖的包：Hibernate3.0；Spring3.0；Struts2；struts-dojo-plugin-2.3.1.2；struts-spring-plugin-2.0.11.2；
项目的总体架构图如下：
以下为前端的呈现界面：
以下为核心代码：
其中，将com.yile.vo包下的Users实体类的代码粘贴如下：
package com.yile.vo;
import java.io.Serializable;
public class User implements Serializable {
private Integer id;
private String userName;
private String password;
public Integer getId() {
return id;
}
public void setId(Integer 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;
}
}
下面将com.yile.action包下的UserAction类的代码粘贴如下：
package com.yile.action;
import java.util.List;
import com.opensymphony.xwork2.ActionSupport;
import com.yile.service.UserService;
import com.yile.vo.User;
@SuppressWarnings("serial")
public class UserAction extends ActionSupport{
private String role;
private String msg;
private User user;
private List<User> users;
private UserService userService;
public String execute() {
return SUCCESS;
}
public String login() {
if(role.equals("admin")){
//System.out.println("role="+role);//测试数据
if(user.getUserName().equals("admin")){
User adminUser=userService.queryUserByName("admin");
if(adminUser.getPassword().equals(user.getPassword())){
msg="登录成功！";
return "admin";
}else{
msg="管理员密码错误，你没有权限登录！";
return "failure";
}
}else{
msg="非管理员，你无权限查看用户记录！";
return "failure";
}
}else{
if(user.getUserName().equals("admin")){
msg="这是普通用户登录界面，请管理员到管理员界面登录！";
return "failure";
}else if(userService.queryUser(user.getUserName(),user.getPassword())){
msg="登录成功！";
return "user";
}else{
msg="用户名或密码错误，请重新填写后登录！";
return "failure";
}
}
}
public String queryAllUser(){
users=userService.queryAll();
return SUCCESS;
}
public String addUser() {
users=userService.queryAll();
System.out.println("size="+users.size());
for(int i=0;i<users.size();i++){
if(user.getUserName().equals(users.get(i).getUserName())){
msg="当前用户已存在！请用其它用户名注册！";
return "addFailure";
}
}
boolean b=userService.addUser(user);
if(b){
msg="注册成功！";
return "addSuccess";
}else{
msg="注册失败！";
return "addFailure";
}
}
public String deleteUser(){
System.out.println("id="+user.getId());
try{
userService.deleteUserById(user.getId());//测试数据
msg="删除成功！";
return SUCCESS;
}catch(Exception e){
return INPUT;
}
}
public String editUser(){
//System.out.println("actionid="+user.getId()+user.getUserName());
userService.updateUser(user);
msg="修改成功！";
this.setRole("admin");
return SUCCESS;
}
public String queryUserById(){
//System.out.println("id="+user.getId());
user=userService.getUserById(user.getId());
return SUCCESS;
}
public UserService getUserService() {
return userService;
}
public void setUserService(UserService userService) {
this.userService = userService;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public List<User> getUsers() {
return users;
}
public void setUsers(List<User> users) {
this.users = users;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
}
以上基本完成后台代码编程，另外还有一些包及类请参看架构缩略图，自行编写。另外有一些orm类的编程，在这里也不再介绍。
以下介绍SSH的关键配置文件，关于Struts2的struts.xml，struts.properties；关于Spring3.3的applicantionContext.xml的配置；关于Hibernate3.0的hibernate.cfg.xml的配置及对象关系映射文件User.hbm.xml的配置；各个配置文件均放在classes目录下，即放在src根目录下。但User.hbm.xml放在com.yile.vo包下；
以下为各个配置文件的详细配置信息：
struts.xml的配置信息：
