Flex4+Spring3+Hibernate3+BlazeDS整合笔记

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:

 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。

 这里有一个个人觉得还蛮不错的Flex教程:Flex系列教程BY蒲公英
