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

<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\”>

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

<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。
如有遗漏请指出
