spring中当小弟我用自动扫描和使用annotation 自动注册bean时，现在flex或者ext要引service如何引用

spring中当我用自动扫描和使用annotation 自动注册bean时，现在flex或者ext要引service怎么引用？

在spring中,当我用自动扫描和使用annotation 自动注册bean时，applicationContext.xml中没有显示的标明bean的id,现在我在flex或者ext要引service怎么引用？这时应该是没法写注释吧？它的id是什么？

其实我就是想调一个servic,但又没有配置文件中明确管理，所以不知怎样去引用，有什么办法呢？

<destination id="abc">
?????? <properties >
?????????? <source>??</source >
?????????? <factory>spring</factory >
?????? </properties>



下面写一下我的配置，大家帮忙看看
flex主文件

public function onResult(event:ResultEvent):void{ //users=ArrayCollection(event.result); Alert.show("get data successfully"); } public function onFault(event:FaultEvent):void{ Alert.show("Error"+event.fault); } 。。。。。。<mx:RemoteObject id="testFlex" destination="testFlexService"><mx:method name="save" result="onResult(event)" fault="onFault(event)"/> </mx:RemoteObject>


remoting-config.xml文件

<service id="remoting-service" default="true"/> </adapters> <destination id="testFlexService"> <properties> <source>testFlexService</source> <factory>spring</factory> </properties> </destination> <default-channels> <channel ref="my-amf"/> </default-channels></service>


service-config.xml文件

<services> <service-include file-path="remoting-config.xml" /> <service-include file-path="proxy-config.xml" /> <service-include file-path="messaging-config.xml" /> </services> <factories> <factory id="spring" src="/img/2012/10/18/1600296579.gif">

spring的配置文件

<context:component-scan base-package="com.superwebchat" /><bean id="testFlexService" src="/img/2012/10/18/1600296579.gif">
public class TestFlexService {public void TestFlexService(){}public String save(){System.out.println("test flex service1 --------------");return "aabbcc";}}




tomcate没报错
flex错误返回提示是：

Error[RPC Fault faultString="Send failed" faultCode="Client.Error.MessageSend" faultDetail="Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Status 404: url: 'http://localhost:8080/WebContent/messagebroker/amf'"]

原来是这个url: 'http://localhost:8080/WebContent/messagebroker/amf'"]
有问题，少了项目名，加个endpoint试试

用的是struts2零配置插件convention，又出现了
WARN? [org.apache.struts2.dispatcher.Dispatcher] - Could not find action or result
There is no Action mapped for namespace /messagebroker and action name amf. - [unknown location]

除非我把

<filter-mapping><filter-name>struts2CleanupFilter</filter-name><url-pattern>*</url-pattern><dispatcher>REQUEST</dispatcher><dispatcher>FORWARD</dispatcher></filter-mapping>


改为

<filter-mapping><filter-name>struts2CleanupFilter</filter-name><url-pattern>*.action</url-pattern><dispatcher>REQUEST</dispatcher><dispatcher>FORWARD</dispatcher></filter-mapping>


但这样的话，我直接访问.action外的页面时就报The Struts dispatcher cannot be found.? This is usually caused by using Struts tags without the associated filter
错，好像是在一些用到struts标签的页面报错。

------------------------------------------
问题补充：
其实和action中type=redirect也有关。没事了，有struts2标签的地方别type=redirect就行了

该问题已经关闭: 问题已解决，如上所述

?

也可以调action,传对象参数

flex中与java对象对应的as对象

package com.Model
{
?/**
? *
? * @author Administrator
? * 与java的pojo对应消息对象
? */?
?
?[RemoteClass(alias="com.superwebchat.entity.entities.Meetingrecord")]
?public class javaMessage
?{
??public var ids:Number;
??//发言者
???public var nickname:String;
??
??//发言内容
??public var msg:String;
??
??//发言时间
??public var chattime:Date;
??
。。。。。。??
??
??public function getIds():Number {
???return ids;
??}
??public function setIds(ids:Number):void {
???this.ids = ids;
??}
??
??public function getNickname():String{
???return nickname;
??}
??public function setNickname(nickname:String ):void {
???this.nickname = nickname;
??}
??
??public function getMsg():String{
???return msg;
??}
??public function setMsg(msg:String ):void {
???this.msg = msg;
??}

??public function getChattime():Date{
???return chattime;
??}
??public function setChattime(chattime:Date ):void {
???this.chattime = chattime;
??}

｝

?

<destination id="meetingrecordAction">
?????? <properties>
?????????? <source>com.superwebchat.web.MeetingrecordAction</source>
?????? </properties>
??? </destination>

?

这样还有问题

比如我这样配置

<destination id="meetingrecordAction">
?????? <properties>
?????????? <source>meetingrecordAction</source>

?????????? <factory>spring</factory>
?????? </properties>
??? </destination>

?

要在Action中对它进行注释，它里面的@autowired的service才会有值

@Controller("meetingrecordAction")//默认就是首字母小写的类名,加上controller就会被spring管理，被注入service，flex就可以调用

?

但是发现在我传了一个as对象进来，service.saveOrUpdate()方法执行的竟然是update,但我是要它新增一条记录的,

为什么会是更新呢，我的对象的id是没有设值的，打印出来看也是0，它怎么就执行了update语句，也不是insert语句呢？

?

?

情况是这样的
我用flex remoting object
sping管理的方式传了一个对象到
action的一个方法save(Meetingrecord mr)中
在这个方法中我想实现新增一条记录的功能
在action加了@Controll注释，所以在flex才能调到它，并且里面的service对象才有值。
hibernate并没有保存这个mr对象
控制台打印出的是update语句
我dao中save方法是getCurrentSession().saveOrUpdate(obj);
为什么是update语句而不是insert语句的？
而且查看数据库也并没有那一条数据被update过
service是有@Transaction注释的，不用flex的话都能运行正确的。
另外，我把saveOrUpdate()方法改成了save()方法
控制台报出下面的错误：

问题补充：
是的,把saveOrUpdate()方法改成save()后就可以保存了，
至于为什么会报唯一性冲突的问题是sequence的问题
//- ORA-00001: 违反唯一约束条件 (ROOT.MRIDS_PRIMARY)
//大概是注释id时对于oracle的sequence 必需加上 allocationSize = 1, initialValue = 1
//没有加上去，声明一个sequence,默认会生成一个hibernate_sequence,
//可以在oracle中的sequence里面看到
//但是每个表都用这个就会生成id重复。
//要为每一个单独注释一个sequence
//并且把表中的数据清空
@Id
??? @SequenceGenerator(name = "generatorSequence", allocationSize = 1, initialValue = 1, sequenceName = "MEETINGRECORD_SEQUENCE")
??? @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "generatorSequence")

但还是不知道为什么用saveOrUpdate方法的时候执行的是update语句
而不是insert语句。
id显示是0,会不会是要id等于null才对呢？我试试吧

------------------------------------------
问题补充：
可能是数据库中的数据是其它库中拷贝过来的，所以sequence也是不对的。

1 楼 javaEEdevelop 2011-03-30   我根本就找不到这个包啊flex.messaging.service.SpringFactory 2 楼 anson_xu 2011-04-03   这个哪里都能找到的flex.jar
