1.使用MyEclipse+Flex插件整合Java&Flex的方法：
https://docs.google.com/fileview?id=0B5pwJS1Mq71jMzM5ZDUwOGMtN2FjNS00Njc2LTlkMjItOTY4ZDU5MDVmNDIx&hl=en
我使用的是第一種。
2.搭建SSH框架
不多說，詳見整個工程：
http://other.sotee.com/2010-03-29/100253.html
3.完成User的ORM——User.java,User.hbm.xml
4.設計用于登錄的LoginService
Login類：
1 package com.linying.service.login;
2
3 import java.util.List;
4
5 import com.linying.dao.CommonDao;
6

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 * 用戶名、密碼正確返回0，否則返回-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 }
80
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"

6.在web-INF-->flex-->service-config.xml文件中加入如下結點：
1 <factories>
2 <factory id="SpringFactory" class="com.linying.beans.SpringFactory"/>
3 </factories>
7.在web-inf-->flex-->remoting-config.xml文件中加入如下結點：
<destination id="login">
<properties>
<factory>SpringFactory</factory>
<source>login</source>
</properties>
</destination>
8.在Flex的主程序中，（本工程為flexLoginDemo.mxml）
增加如下結點：
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”是自定義as方法
整個主程序代碼如下：
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>
7
8 <mx:Script>
9 <![CDATA[
10 import mx.rpc.events.ResultEvent;
11 import mx.controls.Alert;
12 import mx.rpc.events.FaultEvent;
13 import mx.core.IFlexDisplayObject;
14 import components.loginComponent;
15 import components.loginSucceed;
16 import mx.managers.PopUpManager;
17
18 public var lpobj:IFlexDisplayObject;
19 public var lp:loginComponent=loginComponent(lpobj);
20
21 public function loginButtonDown(event:Event):void{
22 login.login(loginComponent(lpobj).userName.text,loginComponent(lpobj).password.text);
23 }
24
25 public function init():void{
26
27 lpobj=PopUpManager.createPopUp(this,loginComponent,true);
28 PopUpManager.centerPopUp(lpobj);
29 loginComponent(lpobj).loginButton.addEventListener(MouseEvent.CLICK,loginButtonDown);
30
31 }
32
33 public var succeedView:loginSucceed=loginSucceed(lpobj);
34
35 private function login_resultHandler(event:ResultEvent):void{
36 var result:int=event.result as int;
37 if(result==0){
38
39 PopUpManager.removePopUp(lpobj);
40 currentState="index";
41
42
43 }else{
44 Alert.show("用戶或者密碼不對","登錄失敗");
45 }
46 }
47
48 private function faultHandler(event:FaultEvent):void {
49 Alert.show(event.fault.toString(), "失敗");
50 }
