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

                //users=ArrayCollection(event.result);
                Alert.show("get data successfully");
            }
            public function onFault(event:FaultEvent):void{
                Alert.show("Error"+event.fault);
            }

spring的配置文件

<context:component-scan base-package="com.superwebchat" />
<bean id="testFlexService" class="com.superwebchat.test.servicetest.TestFlexService"></bean>

<context:component-scan base-package="com.superwebchat" />
<bean id="testFlexService" class="com.superwebchat.test.servicetest.TestFlexService"></bean>

其实我的spring配置中是用自动扫描和annotation注释的。
由于怕service不能被flex里引用，所以加上一个显式声明<bean id="testFlexService" class="com.superwebchat.test.servicetest.TestFlexService"></bean>

java文件如下

public class TestFlexService {
    public void TestFlexService(){

    }
    public String save(){
        System.out.println("test flex service1 --------------");
        return "aabbcc";
    }

}

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>

<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>

<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。
