环境:Eclipse 7.5 + Flex Builder 4 plugin for eclipse.
步骤:
1. 建立J2EE Web工程,略,工程名为Sample。
2. 安装配置BlazeDS。
下载blazeds.war,解压,得到目录结构:
blazeds
├─META-INF
└─WEB-INF
├─classes
├─flex
├─lib
└─src
将blazeds\WEB-INF\lib下的所有jar文件复制到目录Sample\WebRoot\WEB-INF\lib下:
cfgatewayadapter.jarcommons-codec-1.3.jarcommons-httpclient-3.0.1.jarcommons-logging.jarflex-messaging-common.jarflex-messaging-core.jarflex-messaging-opt.jarflex-messaging-proxy.jarflex-messaging-remoting.jarflex-rds-server.jar
xalan.jar
在WEB工程下Sample\WebRoot\WEB-INF目录下新建目录flex,将blazeds\WEB-INF\flex下的所有文件复制到新建目录下:
messaging-config.xml
proxy-config.xmlremoting-config.xmlservices-config.xmlversion.properties
将blazeds\WEB-INF\web.xml中的配置信息复制到WEB工程下的web.xml中:
<!-- Http Flex Session attribute and binding listener support -->
<listener>
<listener-class>flex.messaging.HttpFlexSession</listener-class>
</listener>
<!-- MessageBroker Servlet -->
<servlet>
<servlet-name>MessageBrokerServlet</servlet-name>
<display-name>MessageBrokerServlet</display-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. 添加配置Flex项目。
部署Sample项目到Tomcat,启动Tomcat。下一步需要Web服务验证。
右键点击Sample项目,选择=》添加/更改项目类型=》添加Flex项目类型。
在“使用远程对象访问服务”选项选择BlazeDS,然后Next。
选择Web服务器webapps下的Sample目录作为根文件夹,根URL填写Web项目的Web访问路径,点击“验证配置”,若服务器正常,则验证有效,然后Finish。
4. 配置完毕,可以开始开始BlazeDS开发了。

普通Java Web工程流行使用ssh框架,而当前台使用Flex制作的时候,后台就不需要用Struts了,通过使用BlazeDS远程方法调用即可。
首先,新建Java Web工程,然后添加Flex项目,详情见通过J2EE Web工程添加Flex项目,进行BlazeDS开发 。
随后,导入Jar包,flex相关的jar包在添加Flex项目的时候已经导入,这里主要是导入Spring和Hibernate相关的jar包以及spring和flex集成的jar包,我用的是spring 3.0.3和hibernate 3.2.1。 下面是lib列表:
antlr-2.7.6.jar
asm-2.2.3.jarasm-commons-2.2.3.jarasm-util-2.2.3.jaraspectjlib.jaraspectjrt.jaraspectjweaver.jarbackport-util-concurrent.jarc3p0-0.9.1.jarcfgatewayadapter.jarcglib-nodep-2.1_3.jarcom.springsource.edu.emory.mathcs.backport-3.0.0.jarcom.springsource.net.sf.cglib-2.2.0.jarcom.springsource.org.aopalliance-1.0.0.jarcommons-codec-1.3.jarcommons-collections-3.1.jarcommons-httpclient-3.0.1.jarcommons-io-1.4.jarcommons-lang-2.3.jarcommons-logging.jardom4j-1.6.1.jarehcache-1.2.3.jarflex-messaging-common.jarflex-messaging-core.jarflex-messaging-opt.jarflex-messaging-proxy.jarflex-messaging-remoting.jarflex-rds-server.jarfreemarker-2.3.15.jarhibernate-commons-annotations-3.2.0.Final.jarhibernate-core-3.5.4-Final.jarhibernate-jpa-2.0-api-1.0.0.Final.jarjackson-lgpl-0.9.5.jarjavassist.jarjta-1.1.jarlog4j-1.2.15.jarmysql-connector-java-5.1.13-bin.jarorg.springframework.aop-3.0.3.RELEASE.jarorg.springframework.asm-3.0.3.RELEASE.jarorg.springframework.aspects-3.0.3.RELEASE.jarorg.springframework.beans-3.0.3.RELEASE.jarorg.springframework.context-3.0.3.RELEASE.jarorg.springframework.context.support-3.0.3.RELEASE.jarorg.springframework.core-3.0.3.RELEASE.jarorg.springframework.expression-3.0.3.RELEASE.jarorg.springframework.flex-1.0.3.RELEASE.jarorg.springframework.instrument-3.0.3.RELEASE.jarorg.springframework.instrument.tomcat-3.0.3.RELEASE.jarorg.springframework.jdbc-3.0.3.RELEASE.jarorg.springframework.jms-3.0.3.RELEASE.jarorg.springframework.orm-3.0.3.RELEASE.jarorg.springframework.oxm-3.0.3.RELEASE.jarorg.springframework.test-3.0.3.RELEASE.jarorg.springframework.transaction-3.0.3.RELEASE.jarorg.springframework.web-3.0.3.RELEASE.jarorg.springframework.web.portlet-3.0.3.RELEASE.jarorg.springframework.web.servlet-3.0.3.RELEASE.jarorg.springframework.web.struts-3.0.3.RELEASE.jarslf4j-api-1.5.8.jarslf4j-log4j12-1.5.8.jarxalan.jar
修改配置文件,web.xml,其中最重要的是修改原先MessegeBroker Servlet,改为由Spring web应用前端控制器处理所有请求。
代码<!-- MessageBroker Servlet 单独为Flex配置xml-->
<servlet>
<servlet-name>flex</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/config/flex-application-config.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!--
Map all /messagbroker requests to the DispatcherServlet for handling
-->
<servlet-mapping>
<servlet-name>flex</servlet-name>
<url-pattern>/messagebroker/*</url-pattern>
</servlet-mapping>
配置 flex-application-config.xml,注意增加的几个命名空间,需要包org.springframework.flex-1.0.3.RELEASE.jar,同时在这个文件里定义了bean,在mxml里面会引用到:
flex-application-config.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-1.0.xsd">
<!-- Bootstraps and exposes the BlazeDS MessageBroker simplest form -->
<flex:message-broker/>
<bean id="test" class="sample.Test">
<property name="userDAO">
<ref bean="userDAO" />
</property>
<flex:remoting-destination />
</bean>
</beans>
hibernate的配置,用到c0p0.jar,
daoContext.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:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<!-- 使用c3p0定义数据源Bean -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="com.mysql.jdbc.Driver"/>
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/db"/>
<property name="user" value="user"/>
<property name="password" value="pass"/>
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
<prop key="hibernate.show_sql">
true
</prop>
<prop key="hibernate.format_sql">
true
</prop>
<prop key="hibernate.show_statistics">
false
</prop>
</props>
</property>
<property name="mappingResources">
<list>
<value>sample/dao/User.hbm.xml</value>
</list>
</property>
</bean>
<bean id="userDAO" class="sample.dao.UserDAO">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>
</beans>
test.mxml,这里主要是定义和调用远程对象,远程对象的bean在上面的flex-application-config.xml里面有定义,调用类sample.Test.java中的createUser方法。
<?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.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;
protected function button_clickHandler(event:MouseEvent):void
{
// TODO Auto-generated method stub
test.createUser("name","pass");
}
protected function resulth(event:ResultEvent):void
{
label.text="Succeed!";
}
protected function faulth(event:FaultEvent):void
{
label.text="failed!";
}
]]>
</fx:Script>
<fx:Declarations>
<!-- 将非可视元素(例如服务、值对象)放在此处 -->
<mx:RemoteObject id="ro" destination="test" result="resulth(event);" fault="faulth(event);" />
</fx:Declarations>
<s:Button x="165" y="96" label="点一下" width="414" height="110" fontSize="26" id="button" click="button_clickHandler(event)"/>
<s:Label x="287" y="290" text="远程调用测试" width="202" height="50" verticalAlign="middle" textAlign="center" fontSize="22" id="label"/>
</s:Application>
总结:这篇笔记不大全,只是大概展现了整合这些框架的要点,其中,主要是Flex4,spring3和BlazeDS4之间的整合。尤其需要注意的是jar包的导入。
本文没有涉及到blazeDS和spring整合实现远程方法调用服务和消息服务的配置,会在接下来写。
