spring集成hessian

1、在web.xml中的配置

< context-param >   
     < param-name > contextConfigLocation </ param-name >   
     < param-value >   
        /WEB-INF/config/applicationContext.xml,   
        /WEB-INF/Hessian-servlet.xml   
     </ param-value >   
</ context-param >   
           
< servlet >   
     < servlet-name > Hessian </ servlet-name >   
     < servlet-class >   
        org.springframework.web.servlet.DispatcherServlet   
     </ servlet-class >   
     < load-on-startup > 1 </ load-on-startup >   
</ servlet >   
           
< servlet-mapping >   
     < servlet-name > Hessian </ servlet-name >   
     < url-pattern > /hessian/* </ url-pattern >   
</ servlet-mapping >

2.必须在WEB-INF目录下创建一个文件名格式为Hessian-servlet.xml的配置文件

<!--  业务类  -->   
< bean  id ="hessianService"  class ="com.weijy.webservice.hessian.HessianServiceImpl" />   
           
<!--  远程服务  -->   
< bean  name ="/hessianService"  class ="org.springframework.remoting.caucho.HessianServiceExporter" >   
     < property  name ="service"  ref ="hessianService" />   
     < property  name ="serviceInterface" >   
         < value > com.cjm.webservice.hessian.HessianService </ value >   
     </ property >   
</ bean >

3.客户端调用

String url  =   " http://localhost:8888/spring2/hessian/hessianService " ;   
HessianProxyFactory factory  =   new  HessianProxyFactory();   
HessianService hessianServer  =     
            (HessianService)factory.create(HessianService. class , url);   
String ret  =  hessianServer.sayHello( " Raymond.chen " );  
//.................... 

若使用spring则可通过 HessianProxyFactoryBean在客户端连接服务，在spring的配置中加入：

< bean  id ="hessianService " class ="org.springframework.remoting.caucho.HessianProxyFactoryBean" >
    < property  name ="serviceUrl" value ="http://localhost:8888/spring2/hessian/hessianService" />
    < property  name ="serviceInterface"  value ="com.weijy.webservice.hessian.HessianService" />
</ bean >

加入以上的配置后，就可像使用其他的bean一样去操作了。原来实现一个webservice是可以这么简单的。
