Spring+Hibernate+Flex 实现登录

1.使用MyEclipse+Flex插件整合Java&Flex的方法：
https://docs.google.com/fileview?id=0B5pwJS1Mq71jMzM5ZDUwOGMtN2FjNS00Njc2LTlkMjItOTY4ZDU5MDVmNDIx&hl=en
我使用的是第一种。
2.搭建SSH框架
不多说，详见整个工程： http://other.sotee.com/2010-03-29/100253.html
3.完成User的ORM——User.java,User.hbm.xml
4.设计用于登录的LoginService
Login类：

1 package com.linying.service.login;
2
3 import java.util.List;
4
5 import com.linying.dao.CommonDao;

15 public class Login {
16
17      private String name;
18      private String password;
19      /**
20      * Dao的公用接口
21       */
22      private CommonDao commonDao;
23
24      public CommonDao getCommonDao() {
25          return commonDao;
26     }
27
28      public void setCommonDao(CommonDao commonDao) {
29          this .commonDao = commonDao;
30     }
31      public String getName() {
32          return name;
33     }
34
35      public void setName(String name) {
36          this .name = name;
37     }
38
39      public String getPassword() {
40          return password;
41     }
42
43      public void setPassword(String password) {
44          this .password = password;
45     }
46
47      public Login() {
48          // TODO Auto-generated constructor stub
49     }
50
51      public int login(){
52          return login(name, password);
53     }
54
55      /**
56      * 用户名、密码正确返回0，否则返回-1.
57      * @param name
58      * @param password
59      * @return
60       */
61      public int login(String name,String password){
62         System.out.println( " ----------------------------------> " + name);
63         System.out.println( " ----------------------------------> " + password);
64          if (name == null || name.trim().equals( "" ) || password == null || password.trim().equals( "" )){
65              return - 1 ;
66         }
67         String hql = " select id from User where loginname = ? and password = ? " ;
68         String[] values = new String[ 2 ];
69         values[ 0 ] = name;
70         values[ 1 ] = password;
71         List list = this .getCommonDao().getDataListHql(hql, values);
72          if (list == null || list.isEmpty()){
73              return - 1 ;
74         } else {
75              return 0 ;
76         }
77     }
78
79 }

5.配置applicationContext.xml文件
我的文件配置如下：

1 <? xml version="1.0" encoding="UTF-8" ?>
2 < beans xmlns ="http://www.springframework.org/schema/beans"
3     xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance"

82      </ bean >
83 </ beans >

6.在web-INF-->flex-->service-config.xml文件中加入如下结点：

1 < factories >
2 < factory id ="SpringFactory" class ="com.linying.beans.SpringFactory" />
3 </ factories >

7.在web-inf-->flex-->remoting-config.xml文件中加入如下结点：

< destination id ="login" >
         < properties >
             < factory > SpringFactory </ factory >
             < source > login </ source >
         </ properties >
     </ destination >

8.在Flex的主程序中，（本工程为flexLoginDemo.mxml）
增加如下结点：

1      < mx:RemoteObject id ="login" destination ="login" endpoint ="messagebroker/amf" >
2          < mx:method name ="login" fault ="faultHandler(event)" result ="login_resultHandler(event)" />
3      </ mx:RemoteObject >

其中，“faultHandler”和“login_resultHandler”是自定义as方法
整个主程序代码如下：

1 <? xml version="1.0" encoding="utf-8" ?>
2 < mx:Application xmlns:mx ="http://www.adobe.com/2006/mxml" layout ="absolute" backgroundGradientAlphas ="[1.0, 1.0]" backgroundGradientColors ="[#64F333, #F9F10C]" color ="#FB14ED" xmlns:ns1 ="components.*" creationComplete ="init();" >
3
4      < mx:RemoteObject id ="login" destination ="login" endpoint ="messagebroker/amf" >
5          < mx:method name ="login" fault ="faultHandler(event)" result ="login_resultHandler(event)" />
6      </ mx:RemoteObject >

27                 lpobj=PopUpManager.createPopUp(this,loginComponent,true);
28                     PopUpManager.centerPopUp(lpobj);
29                     loginComponent(lpobj).loginButton.addEventListener(MouseEvent.CLICK,loginButtonDown);

37             if(result==0){

40                 currentState="index";
