Flex与Java中的Object进行交互，需要准备三个内容，一个是Flex主文件，也就是我们的mxml文件，两个Java 类，一个remoting-config.xml。为了减少程序的复杂性，这里只证明Flex可以调用Java中Object进行交互，不进行与数据库的交互。
新建一个Java实体类：SpeakUser.java, 如下：
package com.cx.model;
import java.io.Serializable;
public class SpeakUser implements Serializable{
private static final long serialVersionUID = -4154296753553491429L;
private String userName;
private String userPwd;
private String userTel;
private String userMail;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getUserPwd() {
return userPwd;
}
public void setUserPwd(String userPwd) {
this.userPwd = userPwd;
}
public String getUserTel() {
return userTel;
}
public void setUserTel(String userTel) {
this.userTel = userTel;
}
public String getUserMail() {
return userMail;
}
public void setUserMail(String userMail) {
this.userMail = userMail;
}
}
有的作者说这个实体类需要当做Java代码中方法的返回值传递给Flex中的AS代码，所以需要继承Serializable接口，否则将导致异常的发生。但是经过笔者测试，这个Serializable是可选的，即使不继承，也不会出现什么问题，可能是由于flex的版本所决定的吧。
再创建一Java对象：IntroduceOneself.java,供Flex调用， 类中 以SpeakUser作为参数。代码如下：
package com.cx.action;
import com.cx.model.*;
public class IntroduceOneself {
public String speak(SpeakUser user){
System.out.println("Hello, My Name is: " + user.getUserName());
System.out.println("My telephone is: " + user.getUserTel());
System.out.println("My Email is: " + user.getUserMail());
return "名字叫：" + user.getUserName() + ", 电话是： "
+ user.getUserTel() + ", 邮箱是： "+user.getUserMail()
+ "来访问您，请问您是否要接见?";
}
}
然后创建一个ActionScript类：SpeakUser.as， 用于接受实体类SpeakUser.java的返回值，这里的[Bindable][RemoteClass]是和java代码中的 SpeakUser.java类关联起来。这样利用类型转换将java对象转换成AS对象。代码如下：
package com.flex.model
{
[Bindable]
[RemoteClass(alias="com.cx.model.SpeakUser")]
public class SpeakUser
{
public var userName:String="";
public var userPwd:String ="";
public var userTel:String ="";
public var userMail:String ="";
public function SpeakUser()
{
}
}
}
修改Flex主文件：BlazObject.mxml，在其中调用java类，代码如下：
< mx:Application xmlns:mx ="http://www.adobe.com/2006/mxml" layout ="absolute" minWidth ="955" minHeight ="600" >
< mx:Script >
<![CDATA[
import com.flex.model.SpeakUser;
import mx.controls.Alert;
import mx.rpc.events.ResultEvent;
public function remotingHelloJavaFlex():void
{
var user:SpeakUser = new SpeakUser();
user.userName = nameInputTxt.text;
user.userMail = txtUserMail.text;
user.userPwd = txtPwd.text;
user.userTel = txtTel.text;
someOneCome.speak(user);
someOneCome.addEventListener(ResultEvent.RESULT,getRoHelloRes);
}
private function getRoHelloRes(e:ResultEvent):void{
Alert.show(e.result.toString());
}
private function failed():void{
Alert.show("cuowu");
}
]]>
</ mx:Script >
< mx:Button label ="JAVA Object + FLEX 通信" click ="remotingHelloJavaFlex();" x ="142" y ="234"
fontSize ="12" width ="209" />
< mx:Label text ="姓名" x ="121" y ="55" fontSize ="15" />
< mx:TextInput id ="nameInputTxt" x ="170" y ="55" />
< mx:Label x ="121" y ="103" fontSize ="15" text ="密码：" />
< mx:TextInput id = "txtPwd" x ="170" y ="106" />
< mx:Label x ="121" y ="145" fontSize ="15" text ="电话：" />
< mx:Label x ="121" y ="187" fontSize ="15" text ="邮箱：" />
< mx:TextInput id ="txtTel" x ="170" y ="148" />
< mx:TextInput id ="txtUserMail" x ="170" y ="190" />
< mx:RemoteObject destination ="someOneComeDes" id ="someOneCome" endpoint ="/BlazDSObject/messagebroker/amf" fault ="failed()" />
</ mx:Application >
在这里，Flex是通过AMF协议与Java对象进行交互的，其中endpoint定义了影射文件的消息协议，这个文件来自/WEB-INF/flex /services-config.xml中，影射对象的位置是通过remoting-service.xml影射的代码如下：
< endpoint url = " https://{server.name}:{server.port}/{context.root}/messagebroker/amfsecure " class = " flex.messaging.endpoints.SecureAMFEndpoint " />
< properties >
< add - no - cache - headers > false </ add - no - cache - headers >
</ properties >
</ channel - definition >
remoting-service.xml
< service id ="remoting-service"
class ="flex.messaging.services.RemotingService" >
< adapters >
< adapter-definition id ="java-object" class ="flex.messaging.services.remoting.adapters.JavaAdapter" default ="true" />
</ adapters >
< default-channels >
< channel ref ="my-amf" />
</ default-channels >
< destination id ="someOneComeDes" >
< properties >
