Java 请求的操作类方法在ajax调用中运行两次？

我使用JQuery

getJSON（）

方法从服务器获取JSON数据。 一切都运行良好，但有一个小问题，我请求的方法调用了两次，我在响应JSON中得到了类似的值

Javascript部分：

$.getJSON( "getAgentDataAgentDetails", {campaign: campaign} , function(data) {
          var list = data.agentList;
          alert("Response : " + list.length);
      });

alertbox返回：“响应：4”

struts映射：

   <action name="*AgentDetails" method="{1}" class="com.contaque.monitor.AgentListAction">
        <result name="getAgentData" type="json"/>
    </action>

Java控制台O/p：

Campaign : avis
Agent List : [Agent{name=avis, extension=150, skill=English, phoneNumber=9876541230,status=INCALL, callType=IN, time=10:50:19}, Agent{name=sys, extension=857, skill=Hindi, phoneNumber=9658741235, status=WAITING, callType=OUT, time=08:40:16}]
Campaign : avis
Agent List : [Agent{name=avis, extension=150, skill=English, phoneNumber=9876541230, status=INCALL, callType=IN, time=10:50:19}, Agent{name=sys, extension=857, skill=Hindi, phoneNumber=9658741235, status=WAITING, callType=OUT, time=08:40:16}, Agent{name=avis, extension=150, skill=English, phoneNumber=9876541230, status=INCALL, callType=IN, time=10:50:19}, Agent{name=sys, extension=857, skill=Hindi, phoneNumber=9658741235, status=WAITING, callType=OUT, time=08:40:16}]

在哪里调用getJSON？什么是

agentList

？@Ankit:发布您的JSP。什么是

AgentDetails

方法？

Campaign : avis
Agent List : [Agent{name=avis, extension=150, skill=English, phoneNumber=9876541230,status=INCALL, callType=IN, time=10:50:19}, Agent{name=sys, extension=857, skill=Hindi, phoneNumber=9658741235, status=WAITING, callType=OUT, time=08:40:16}]
