java - 从 javascript (ajax) 调用 Spring Controller 方法未触发？

Question

从 javascript 向 Spring Controller 方法发出请求，如下所示

<script language="javascript" type="text/javascript">
          var xmlHttp
          var xmlHttp
          function show()
          {   
              if(typeof XMLHttpRequest != "undefined")
              {
              xmlHttp= new XMLHttpRequest();
               }
              else if (window.ActiveXObject)
              {
                  xmlHttp= new ActiveXObject("Microsoft.XMLHTTP");
              }
              if(xmlHttp==null)
              {
                  alert("Browser does not support XMLHTTP Request")
                  return;
              }
              var FAC_LICENSE_NO=document.getElementById("FAC_LICENSE_NO").value;
              //var url="/Final/WEB-INF/jsp/SurrenderViews/Ajax.jsp";
              var url="http://localhost:8080/Final/Ajax.FSu";
              url +="?param1="+FAC_LICENSE_NO;
              alert(url);
              xmlHttp.onreadystatechange = stateChange;
              xmlHttp.open("GET", url, true);
              xmlHttp.send(null);         
            }   
          function stateChange()
          {   
                if(xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
                {
                    document.getElementById("factoryname").innerHTML=xmlHttp.responseText
                }
         }
    </script>

和我的 Controller

public class PhaseTwoFormSurrenderOfLicense extends MultiActionController implements Connections {

     public ModelAndView DataInput(HttpServletRequest request,HttpServletResponse response) 
     {
         return new ModelAndView("SurrenderViews/DataInput");
     } 
     public String Ajax(HttpServletRequest request,HttpServletResponse response) 
     {
           System.out.println("Maritammanafvara");
           String returning="<input type=\"text\" style=\"border: none\" name=\"Factory_name\" readonly=\"readonly\" value=\"HIHI\">";
           return returning;

     } 
}

在上面的代码中，我可以从 html anchor 标记调用 DataInput 和 Ajax 方法，但不能从 XMLHttpRequest(ajax) 对象调用。谁能告诉一下这个地区吗？

你能试试吗 var url="Ajax.FSu";

而不是

var url="http://localhost:8080/Final/Ajax.FSu";
