dwr实现page分页

（1）在web.xml中配置DWRServlet如下：
   <servlet>
   <servlet-name>dwr-invoker</servlet-name>
   <servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>
   <init-param>
     <param-name>debug</param-name>
     <param-value>true</param-value>
   </init-param>
 </servlet>
  <servlet-mapping>
   <servlet-name>dwr-invoker</servlet-name>
   <url-pattern>/dwr/*</url-pattern>
 </servlet-mapping>
(2) 在dwr.xml中配置

<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://www.getahead.ltd.uk/dwr//dwr20.dtd">
<dwr>
 <allow> 
   <!--leadService为Spring 中配置的service 负责取分页数据,返回page对象 --> 
   <create javascript="LeadService" creator="spring">
     <param name="beanName" value="leadService"></param><!--可以采用name="class"  value="com.infowarelab.leadmanagement.service.LeadService"-->
     <include method="listLeadDwr" />    
   </create> 
   <!--返回的page 对象 -->   
   <convert match="org.springside.core.dao.support.Page" converter="bean">
     <param name="include" value="result,totalCount"></param>     
   </convert>
   <!--page对象中List<Lead> reslut -->
   <convert converter="bean" match="com.infowarelab.leadmanagement.model.Lead" >
     <param name="include" value="id,lastName,firstName,company,emailAddress,rank"></param>
   </convert>
   <!-- Lead对象中的LeadRank属性-->
   <convert converter="bean" match="com.infowarelab.leadmanagement.model.LeadRank" >
     <param name="include" value="id,name"></param>
   </convert>  
  <allow>
</dwr>
