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.jar
        asm-commons-2.2.3.jar
        asm-util-2.2.3.jar

        org.springframework.context-3.0.3.RELEASE.jar
        org.springframework.context.support-3.0.3.RELEASE.jar
        org.springframework.core-3.0.3.RELEASE.jar
        org.springframework.expression-3.0.3.RELEASE.jar
        org.springframework.flex-1.0.3.RELEASE.jar

        slf4j-api-1.5.8.jar
        slf4j-log4j12-1.5.8.jar
        xalan.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。
    
    复制代码
    代码
          
        <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>  
      
          
        <servlet-mapping>  
            <servlet-name>flex</servlet-name>  
            <url-pattern>/messagebroker/*</url-pattern>  
        </servlet-mapping>
    复制代码
     
    
     
    
     
    
    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：
    
    复制代码
    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">
    
         
        <flex:message-broker/>  
        
        <bean id="test" class="sample.Test">
              <property name="userDAO">
                <ref bean="userDAO" />
            </property>
              <flex:remoting-destination />
        </bean>
    </beans>
     
    复制代码
     
    
     
    
     
    
     
    
     
    
    hibernate的配置，用到c0p0.jar，
    
     daoContext.xml
    
     复制代码
    <?xml version="1.0" encoding="UTF-8"?>
    <beans
        xmlns="http://www.springframework.org/schema/beans"
        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">
        
        
        <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>
    复制代码
     
    
     
    
     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"?>

     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。
