flex eclipse综合spring入门

首先下载FlashBuilder_4_7_LS10_win64.exe试了几eclipse安装没有成功插头，含有myeclipse8.5、spring sts2.9.2、eclipse3.5、j2eeeclipse版本号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最终配置成功了。myeclipse8.5不行，spring sts能够了。

spring sts部署应用跟myeclipse不一样，比較类似eclipse。

用sts整合flex和java有几个步骤：

1：新建动态webprojectflexweb，创建web.xml

2：blazeds-turnkey-4.0.0.14931.zip解压，复制blazed两个目录flex和lib到WEB-INF下。里面是blaze的jar包和flex配置文件，然后改动web.xml增加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。加入/更改项目类型>加入flex类型项目，第一步，应用程序类型选择J2EE。下方选择BlazeDS。第二部根目录填入项目在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，输出目录使用默认E:\workspaces\sts\flexweb\WebContent\flexweb-debug，点击finish

4：转换完毕后，文件夹有些变化，右键项目>properties>flex构建路径，主源文件夹改为flex_src，然后把自己主动生成的src文件夹下的flexweb.mxml移动到flex_src下，环境搭建就算完毕了

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（比如服务、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>

当中

<s:RemoteObject id="myFlex" destination="mytest" result="myFlex_resultHandler(event)"/>

指定了一个调用Java的类Hello，mytest相应到remoting-config.xml

在WEB-INFO/flex文件夹下remoting-config.xml增加

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

result相应的是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

訪问路径是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，右键点击又一次创建模板

加入Spring支持

1：web.xml增加

<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.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/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增加

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

加入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：改动remoting-config.xml

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

5：改动对应的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改动默认浏览器为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执行，打开的IE才会打印trace，直接訪问网址是不行的。
