ajax与spring 结合

转载 http://www.javabc.com/Html/javakyjs/java_kyajax/87263814176488.html

Spring的集成几乎异常简单,只需要更改配置文件而已.

页面的代码不用动，例如

doc.simple-spring.jsp

< script language = " javascript " >
var  springEndPoint = " <%=request.getContextPath()%>/remoting/Spring-buffalo " ;
function  pageMethod() {
  var  buffalo  =   new  Buffalo(springEndPoint);
 buffalo.remoteCall( " yourObject.yourMethod " ,[],  function (reply) {
   var  Obj  =  reply.getResult();
 })
}
</ script >

web部署描述文件
web.xml

         < servlet-class >                   org.springframework.web.servlet.DispatcherServlet                 </ servlet-class >

以前的buffalo-service.properties文件则不用,applicationContext.xml所替代之.
其中引用到的bean可以是任意被Spring托管的bean.这个Controller可以被任意任意方式的ServletDispather调用.

applicationContext.xml

< beans >     
     < bean  name ="simpleService"  class ="net.buffalo.demo.simple.SimpleService" >           </ bean >
     < bean  name ="numberService"  class ="net.buffalo.demo.numberguess.NumberGuessService" >          </ bean >     
</ beans >

remoting-servlet.xml

< beans >
   < bean  name ="/Spring-buffalo"  class ="net.buffalo.spring.BuffaloServiceExporter" >
     < property  name ="services" >
             < map >
                 < entry  key ="simpleService" >
                     < ref  bean ="simpleService" />
                 </ entry >
         < entry  key ="numberService" >
                     < ref  bean ="numberService" />
                 </ entry >
             </ map >
         </ property > </ bean > </ beans >
