手把手教你使用flex eclipse整合spring

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

  flex.messaging.HttpFlexSession
 

 
 
 
  MessageBrokerServlet
  flex.messaging.MessageBrokerServlet
  
   services.configuration.file
   /WEB-INF/flex/services-config.xml
  
  1
 
 
  MessageBrokerServlet
  /messagebroker/*
 

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http://localhost:8080/flexweb，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：

其中

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

    
      com.hongbo.Hello
    
  

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http://localhost:8080/flexweb/flexweb-debug/flexweb.html

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

  contextConfigLocation
  /WEB-INF/classes/applicationContext.xml 
 
 
  org.springframework.web.context.ContextLoaderListener
 

2：src下创建applicationContext.xml

3：WEB-INF/flex/service-config.xml加入

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

    
     spring
      hello
    
  

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。
