 9 
10 import nuc.sw.vo.User;
11 
12 public class LoginRegAction extends ActionSupport implements ModelDriven<User>{
13     private User user=new User();
14    
15 //contextPath server.xml
16     
17     public User getModel() {
18         return user;
19     };
20 //action    
21         public String LoginMethod() throws Exception {
22             // TODO Auto-generated method stub
23             //登录逻辑
24             if(user.getUsername().equals("张丹")&&user.getPassword().equals("123")){
25                 ActionContext.getContext().getSession().put("loginUser",user.getUsername());
26                 ActionContext.getContext().getSession().put("loginPass",user.getPassword());
27                 ActionContext.getContext().getSession().put("loginType",user.getUsertype());
28                 return SUCCESS;
29             }
30             else{
31                 
32                 ActionContext.getContext().put("error", "用户名或者密码错误");
33                 return ERROR;
34             }
35         }
36         public String RegisterMethod() throws Exception {
37             // TODO Auto-generated method stub
38             if(user.getUsername().equals("张丹")&&user.getPassword().equals("123")){
39                 ActionContext.getContext().getSession().put("registerUser",user.getUsername());

44             else{
45                 
46                 ActionContext.getContext().put("error", "用户名或者密码错误");
47                 return ERROR;
48             }
49         }
50         
51
