BlazeDS 与Spring集成指南之一

Springsource与Adobe合作发布了Spring与BlazeDS集成的项目Spring BlazeDS Integration，通过Spring BlazeDS Integration可以把Spring的Bean暴露为BlazeDS的Flex Remoting Service，这样Flex客户端就能够通过AMF调用Spring 暴露出来的Bean，有效简化BlazeDS配置及开发难度。

配置好BlazeDS的开发环境

创建com.yeeach.HelloWorldService,内容如下：

package com.yeeach;

public class HelloWorldService {
    public String hello(String var1) {
        return "hello " + var1;
    }
    public String world(String var1) {
        return "world " + var1;
    }
}

修改web.xml，内容如下：
<?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>Spring BlazeDS Integration Samples</display-name>
    <description>Spring BlazeDS Integration Sample Application</description>

    <!– Http Flex Session attribute and binding listener support –>
    <listener>
        <listener-class>flex.messaging.HttpFlexSession</listener-class>
    </listener>

    <!– The front controller of this Spring Web application, responsible for handling all application requests –>
    <servlet>
        <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                   classpath:/applicationContext*.xml
                classpath*:/applicationContext.xml
                /WEB-INF/applicationContext*.xml
            </param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!– Map all *.spring requests to the DispatcherServlet for handling –>
    <servlet-mapping>
        <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
        <url-pattern>/spring/*</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.htm</welcome-file>
    </welcome-file-list>

</web-app>


修改flex/services-config.xml，内容如下
<?xml version="1.0" encoding="UTF-8"?>
<services-config>

    <services>
        <service-include file-path="remoting-config.xml" />
        <service-include file-path="proxy-config.xml" />

           <channel ref="my-amf"/>
        </default-channels>
    </services>

    <channels>
        <channel-definition id="my-streaming-amf" class="mx.messaging.channels.StreamingAMFChannel">
            <endpoint url="http://{server.name}:{server.port}/{context.root}/spring/messagebroker/streamingamf" class="flex.messaging.endpoints.StreamingAMFEndpoint"/>
        </channel-definition>
        <channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel">

                <polling-enabled>true</polling-enabled>
                <polling-interval-seconds>4</polling-interval-seconds>
            </properties>
        </channel-definition>

        <channel-definition id="my-http" class="mx.messaging.channels.HTTPChannel">
            <endpoint url="http://{server.name}:{server.port}/{context.root}/spring/messagebroker/http" class="flex.messaging.endpoints.HTTPEndpoint"/>
        </channel-definition>

        <channel-definition id="my-secure-http" class="mx.messaging.channels.SecureHTTPChannel">

            <properties>
                <add-no-cache-headers>false</add-no-cache-headers>
            </properties>
        </channel-definition>

    </channels>

    <logging>
        <target class="flex.messaging.log.ConsoleTarget" level="info">
            <properties>
                <prefix>[BlazeDS] </prefix>
                <includeDate>false</includeDate>

                <pattern>Configuration</pattern>
            </filters>
        </target>
    </logging>

</services-config>

修改flex/remoting-config.xml，内容如下
<?xml version="1.0" encoding="UTF-8"?>
<service id="remoting-service"
    class="flex.messaging.services.RemotingService">

    <adapters>
        <adapter-definition id="java-object" class="flex.messaging.services.remoting.adapters.JavaAdapter" default="true"/>
    </adapters>

    <default-channels>
        <channel ref="my-amf"/>
    </default-channels>
</service>
