flex eclipse整合spring入门
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：
<?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
<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。
