以后再用到的话，至少能起个参考作用
java实现，struts2的Action中，依赖HttpServletRequest
 
 
package net.dookoo.web.action;
 
import java.util.Enumeration;
 
import javax.servlet.http.HttpServletRequest;
 
import com.linktong.webframework.action.BaseAction;

      public int getObjCount() {
            // TODO Auto-generated method stub
            return 0;
      }
