最先下载flashbuilder_4_7_ls10_win64.exe试了几个eclipse安装插件都没成功，包括myeclipse8.5、spring sts2.9.2、eclipse3.5、j2eeeclipse版本4.2.0，后来搞了一个flashbuilder_4_ls10.exe安装完找不到插件安装文件原来这个是单独版，必须插件版才行，最后下载flashbuilder_4_plugin_ls10.exe终于配置成功了，myeclipse8.5不行，spring sts可以了。

spring sts部署应用跟myeclipse不一样，比较类似eclipse。

用sts整合flex和java有几个步骤：

1：新建动态web工程flexweb，创建web.xml

2： blazeds-turnkey-4.0.0.14931.zip解压，复制blazed两个文件夹flex和lib到web-inf下，里面是blaze的jar包和flex配置文件，然后修改web.xml加入blaze支持

<listener>
  <listener-class>flex.messaging.httpflexsession</listener-class>
 </listener>

 
 <!-- messagebroker servlet -->
 <servlet>
  <servlet-name>messagebrokerservlet</servlet-name>
  <servlet-class>flex.messaging.messagebrokerservlet</servlet-class>
  <init-param>
   <param-name>services.configuration.file</param-name>
   <param-value>/web-inf/flex/services-config.xml</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
 </servlet>
 <servlet-mapping>
  <servlet-name>messagebrokerservlet</servlet-name>
  <url-pattern>/messagebroker/*</url-pattern>
 </servlet-mapping>

3：项目右键，添加/更改项目类型>添加flex类型项目，第一步，应用程序类型选择j2ee，下方选择blazeds，第二部根文件夹填入项目在workspase的路径加一个webcontent，如e:\workspaces\sts\flexweb\webcontent，根url填，上下文根目录/flexweb，输出文件夹使用默认e:\workspaces\sts\flexweb\webcontent\flexweb-debug，点击finish
4：转换完成后，目录有些变化，右键项目>properties>flex构建路径，主源文件夹改为flex_src，然后把自动生成的src目录下的flexweb.mxml移动到flex_src下，环境搭建就算完成了

helloworld

flexweb.mxml：

<?xml version="1.0" encoding="utf-8"?>
<s:application xmlns:fx="http://ns.adobe.com/mxml/2009"   
     xmlns:s="library://ns.adobe.com/flex/spark"   
     xmlns:mx="library://ns.adobe.com/flex/mx" minwidth="955" minheight="600">  
 
 <fx:script>  
  <![cdata[  
   import mx.controls.alert;  
   import mx.rpc.events.resultevent;  
   
   protected function myflex_resulthandler(event:resultevent):void{  
    var name:string=event.result as string;  
    alert.show(name);  
   }  
   protected function button1_clickhandler(event:mouseevent):void  
   {   
    myflex.sayhello(txtname.text);  
   }  
  ]]>  
 </fx:script>  
 
 <fx:declarations>  
  <!-- 将非可视元素（例如服务、值对象）放在此处 -->  
  <s:remoteobject id="myflex" destination="mytest" result="myflex_resulthandler(event)"/>  
 </fx:declarations>  
 <s:button x="209" y="135" label="按钮" click="button1_clickhandler(event)"/>  
 <s:textinput x="166" y="81" id="txtname"/>  
 <s:label x="10" y="81" text="请输入内容：" fontsize="15" fontweight="bold" fontfamily="中易黑体"/>  
</s:application>

其中

<s:remoteobject id="myflex" destination="mytest" result="myflex_resulthandler(event)"/>

指定了一个调用java的类hello，mytest对应到remoting-config.xml

在web-info/flex目录下remoting-config.xml加入

<destination id="mytest">
    <properties>
      <source>com.hongbo.hello</source>
    </properties>
  </destination>

result对应的是java方法调用的回调函数
建一个普通java类

package com.hongbo;

public class hello {

 public string sayhello(string name){
  system.out.println("------------------------------------");
  return "hello first demo " + name;
 }
}

这样就ok了

访问路径是

第一次会报404，problems提示无法创建html包装器，右键点击重新创建模板

添加spring支持

1：web.xml加入

<context-param>
  <param-name>contextconfiglocation</param-name>
  <param-value>/web-inf/classes/applicationcontext.xml </param-value>
 </context-param>
 <listener>
  <listener-class>org.springframework.web.context.contextloaderlistener</listener-class>
 </listener>

2：src下创建applicationcontext.xml

<?xml version="1.0" encoding="utf-8"?>
<beans xmlns="http://www.51sjk.com/Upload/Articles/1/0/246/246676_20210620000549107.jpg"
 xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:aop="http://www.51sjk.com/Upload/Articles/1/0/246/246676_20210620000549545.jpg"
 xmlns:tx="http://www.51sjk.com/Upload/Articles/1/0/246/246676_20210620000549560.jpg"
 xsi:schemalocation="http://www.51sjk.com/Upload/Articles/1/0/246/246676_20210620000549107.jpg http://www.51sjk.com/Upload/Articles/1/0/246/246676_20210620000549107.jpg/spring-beans-2.0.xsd

 http://www.51sjk.com/Upload/Articles/1/0/246/246676_20210620000549560.jpg http://www.51sjk.com/Upload/Articles/1/0/246/246676_20210620000549560.jpg/spring-tx-2.0.xsd">

 <bean id="hello" class="com.hongbo.hello">
  <property name="testspring">
   <ref bean="testspring"/>
  </property>
 </bean>
 <bean id="testspring" class="com.hongbo.test.impl.testspringimpl"/>
</beans>

3：web-inf/flex/service-config.xml加入

<factories>
   <factory id="spring" class="com.hongbo.springfactory" /> 
 </factories>

添加java类

package com.hongbo;


import org.springframework.beans.beansexception;
import org.springframework.beans.factory.nosuchbeandefinitionexception;
import org.springframework.context.applicationcontext;
import org.springframework.web.context.support.webapplicationcontextutils;
import flex.messaging.factoryinstance;
import flex.messaging.flexfactory;
import flex.messaging.config.configmap;
import flex.messaging.services.serviceexception;
public class springfactory implements flexfactory {
 private static final string source = "source";

 public void initialize(string id, configmap configmap) {
 }

 public factoryinstance createfactoryinstance(string id, configmap properties) {
  springfactoryinstance instance = new springfactoryinstance(this, id,
    properties);
  instance.setsource(properties.getpropertyasstring(source, instance
    .getid()));
  return instance;
 } // end method createfactoryinstance()  

 public object lookup(factoryinstance inst) {
  springfactoryinstance factoryinstance = (springfactoryinstance) inst;
  return factoryinstance.lookup();
 }

 static class springfactoryinstance extends factoryinstance {
  springfactoryinstance(springfactory factory, string id,
    configmap properties) {
   super(factory, id, properties);
  }

  public string tostring() {
   return "springfactory instance for id=" + getid() + " source="
     + getsource() + " scope=" + getscope();
  }

  public object lookup() {
   applicationcontext appcontext = webapplicationcontextutils.getwebapplicationcontext(flex.messaging.flexcontext.getservletconfig().getservletcontext());
   string beanname = getsource();

   try {
    return appcontext.getbean(beanname);
   } catch (nosuchbeandefinitionexception nexc) {
    serviceexception e = new serviceexception();
    string msg = "spring service named '" + beanname
      + "' does not exist.";
    e.setmessage(msg);
    e.setrootcause(nexc);
    e.setdetails(msg);
    e.setcode("server.processing");
    throw e;
   } catch (beansexception bexc) {
    serviceexception e = new serviceexception();
    string msg = "unable to create spring service named '"
      + beanname + "' ";
    e.setmessage(msg);
    e.setrootcause(bexc);
    e.setdetails(msg);
    e.setcode("server.processing");
    throw e;
   }
  }

 }

}

4：修改remoting-config.xml

<destination id="mytest">
    <properties>
     <factory>spring</factory>
      <source>hello</source>
    </properties>
  </destination>

5：修改相应的java类

package com.hongbo;

import com.hongbo.test.testspring;

public class hello {

 private testspring testspring;
 
 public void settestspring(testspring testspring) {
  this.testspring = testspring;
 }
 
 public string sayhello(string name){
  return testspring.testspring(name);
 }
}

package com.hongbo.test;

public interface testspring {

 string testspring(string name);
}

package com.hongbo.test.impl;

import com.hongbo.test.testspring;

public class testspringimpl implements testspring{

 public string testspring(string name){
  system.out.println("test spring-------------------------------------"+name);
  return "test spring "+name;
 }
}

最后，flex打印语句trace不会打印到控制台，要先卸载flashplayer再安装一个debuger版的flashplayer，下载flashplayer_uninstall.zip，卸载，下载flashplayer10r12_36_winax_debug.exe，安装，卸载安装后好像谷歌浏览器没影响，然后eclipse修改默认浏览器为ie，window>preferences>general>web browser，选择internet explorer，最后还有，启动tomcat后，必须在mxml上面右键debug运行，打开的ie才会打印trace，直接访问网址是不行的。
