BlazeDs + Spring 整合
在Flex + BlazeDS + java 整合完成的基础上
1. 修改web.xml配置文件。原来是通过blazeds拦截，现在改成用spring 拦截。
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<display-name>BlazeDS</display-name>
<description>BlazeDS Application</description>
<!-- Http Flex Session attribute and binding listener support -->
<listener>
<listener-class>flex.messaging.HttpFlexSession</listener-class>
</listener>
<!-- 定义 spring flex 集成的配置，使用单独的配置文件。
不使用在一个applicatonContext.xml中import springFlex.xml的方法
spring flex 一定要用DispatcherServlet 方法。不能用ContextLoaderListener -->
<servlet>
<servlet-name>MessagebrokerServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Map /spring/* requests to the DispatcherServlet -->
<servlet-mapping>
<servlet-name>MessagebrokerServlet</servlet-name>
<url-pattern>/messagebroker/*</url-pattern>
</servlet-mapping>
<!-- 定义 spring flex 集成的配置 结束-->

</web-app>
2. 添加Spring配置文件：applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:flex="http://www.springframework.org/schema/flex" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/flex http://www.springframework.org/schema/flex/spring-flex-1.5.xsd"> <!-- spring 配置文件来定义 --> <flex:message-broker> <flex:message-service default-channels="my-amf, my-polling-amf" /> </flex:message-broker> <bean id="hello" class="test.HelloWord"> <flex:remoting-destination/> </bean> </beans>
3.Flex客户端调用
<?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"
creationComplete="application1_creationCompleteHandler(event)">
<fx:Script>
<![CDATA[
import mx.controls.Alert;
import mx.events.FlexEvent;
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;
protected function application1_creationCompleteHandler(event:FlexEvent):void
{
ro.getName("XOXOXO");
}
protected function ro_resultHandler(event:ResultEvent):void
{
Alert.show(event.result as String);
}
protected function ro_faultHandler(event:FaultEvent):void
{
Alert.show(event.fault.faultString);
}
]]>
</fx:Script>
<fx:Declarations>
<s:RemoteObject id="ro"
result="ro_resultHandler(event)"
fault="ro_faultHandler(event)"
destination="hello"/>
</fx:Declarations>
</s:Application>
* 启动服务器，开始运行，弹出 发送失败。原因是因为没有定义endpoint的，但是有不希望在Flex客户端中硬编码写入endpoint。怎么解决呢？
1. 先在Flex项目中添加一个编译参数：-services "D:\carsonsoft\commhome\webapps\DLUvsServer\WEB-INF\flex\services-config.xml"
2. 在services-config.xml中添加默认的通道和端点：
<services>
<service-include file-path="remoting-config.xml" />
<service-include file-path="proxy-config.xml" />
<service-include file-path="messaging-config.xml" />
<default-channels>
<channel ref="my-amf" />
</default-channels>
</services>
