flex eclipse整合spring入門
阿新 • • 發佈：2018-11-17
最先下載FlashBuilder_4_7_LS10_win64.exe試了幾個eclipse安裝外掛都沒成功，包括myeclipse8.5、spring sts2.9.2、eclipse3.5、j2eeeclipse版本4.2.0，後來搞了一個FlashBuilder_4_LS10.exe安裝完找不到外掛安裝檔案原來這個是單獨版，必須外掛版才行，最後下載FlashBuilder_4_Plugin_LS10.exe終於配置成功了，myeclipse8.5不行，spring sts可以了。
spring sts部署應用跟myeclipse不一樣，比較類似eclipse。
用sts整合flex和java有幾個步驟：
1：新建動態web工程flexweb，建立web.xml
2：blazeds-turnkey-4.0.0.14931.zip解壓，複製blazed兩個資料夾flex和lib到WEB-INF下，裡面是blaze的jar包和flex配置檔案，然後修改web.xml加入blaze支援
<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：專案右鍵，新增/更改專案型別>新增flex型別專案，第一步，應用程式型別選擇J2EE，下方選擇BlazeDS，第二部根資料夾填入專案在workspase的路徑加一個WebContent，如E:\workspaces\sts\flexweb\WebContent，根URL填http://localhost:8080/flexweb，上下文根目錄/flexweb，輸出資料夾使用預設E:\workspaces\sts\flexweb\WebContent\flexweb-debug，點選finish
4：轉換完成後，目錄有些變化，右鍵專案>properties>flex構建路徑，主原始檔夾改為flex_src，然後把自動生成的src目錄下的flexweb.mxml移動到flex_src下，環境搭建就算完成了
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>
<!-- 將非可視元素（例如服務、值物件）放在此處 -->
<s:RemoteObject id="myFlex" destination="mytest" result="myFlex_resultHandler(event)"/>
</fx:Declarations>
<s:Button x="209" y="135" label="按鈕" click="button1_clickHandler(event)"/>
<s:TextInput x="166" y="81" id="txtName"/>
<s:Label x="10" y="81" text="請輸入內容：" fontSize="15" fontWeight="bold" fontFamily="中易黑體"/>
</s:Application>其中
<s:RemoteObject id="myFlex" destination="mytest" result="myFlex_resultHandler(event)"/>
指定了一個呼叫Java的類Hello，mytest對應到remoting-config.xml
在WEB-INFO/flex目錄下remoting-config.xml加入
<destination id="mytest">
<properties>
<source>com.hongbo.Hello</source>
</properties>
</destination>result對應的是java方法呼叫的回撥函式
建一個普通java類
package com.hongbo;
public class Hello {
public String sayHello(String name){
System.out.println("------------------------------------");
return "Hello First Demo " + name;
}
}這樣就OK了
訪問路徑是http://localhost:8080/flexweb/flexweb-debug/flexweb.html
第一次會報404，problems提示無法建立html包裝器，右鍵點選重新建立模板
新增Spring支援
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下建立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>
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：修改相應的Java類
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;
}
}
最後，flex列印語句trace不會列印到控制檯，要先解除安裝flashplayer再安裝一個debuger版的flashplayer，下載flashplayer_uninstall.zip，解除安裝，下載flashplayer10r12_36_winax_debug.exe，安裝，解除安裝安裝後好像谷歌瀏覽器沒影響，然後eclipse修改預設瀏覽器為IE，window>preferences>General>Web browser，選擇Internet Explorer，最後還有，啟動tomcat後，必須在mxml上面右鍵debug執行，開啟的IE才會列印trace，直接訪問網址是不行的。
有遺漏請指出
