用Spring MVC不在TOMCAT8里配置域名时不报错，配完点两下就报如下错误，求解

这是在tomcat8里配置的域名

<Host name="www.xxx.com" debug="0" appBase="D:\\Program Files\\apache-tomcat-8.0.17\\webapps"
       unpackWARs="true" autoDeploy="true"
       xmlValidation="false" xmlNamespaceAware="false">
       <Alias>www.xxx.cn</Alias>
       <Alias>www.xxx.net</Alias>
       <Alias>www.xxx.com.cn</Alias>
       <Logger className="org.apache.catalina.logger.FileLogger"
                 directory="logs"  prefix="localhost_log." suffix=".txt"
            timestamp="true"/>
       <Context path="" docBase="D:\\Program Files\\apache-tomcat-8.0.17\\webapps\\sp"  reloadable="true" caseSensitive="false" debug="0"></Context>
</Host>

点击下报的错误信息如下：

你的代码当中有未关闭的请求

spring mvc有啥请求需要关？？？没太明白

@RequestMapping(value = "/homeTabPage")
public String  homePage(PageHomeParam pageParam,Fbsp queryParam,HttpServletRequest request,ModelMap map){
        String spmc = "";//PageHomeParam
        String spflid = request.getParameter("spflid");
try {
if(StringUtils.isNotEmpty(request.getParameter("spmc")) ) {
spmc = new String(request.getParameter("spmc").getBytes("ISO-8859-1"),"UTF-8");
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
queryParam.setFbspId(spflid);
queryParam.setFbspCpmc(spmc);
PageData<Fbsp> data=this.fbspService.findHomePageData(pageParam, queryParam);
request.setAttribute("Fbsp", queryParam);
request.setAttribute("data", data);

String queryHTML=BeanUtils.getNotEpmtyValueList(queryParam);
queryHTML+=BeanUtils.getNotEpmtyValueList(pageParam);
request.setAttribute("queryCondHTML", queryHTML);
String retStr="adminTab";

return retStr;
}

这个方有啥不对的？？

我是第一个页没全部运行完，然后就点第二个面，反复点就出这个错误

那位知道，指点一下，谢谢

页面当中的response当中应该清空，所以说有未关闭的请求

你说的是jsp页中的吗，JSP里我也没有用到过response呀

经过跟踪程序，发现JSP中用这段报的原因
<%@ page import="org.apache.commons.codec.binary.Base64"%>
<%for(int i=0;i<pageData.getRows().size();i++){
  Fbsp u=pageData.getRows().get(i);
  String picPath=new String( Base64.encodeBase64(u.getFbspYh().getBytes("utf-8")));
%>
<a href="<%=path %>/dd/commodity/detailPage/<%=u.getFbspId() %>" target="_parent"><img class="pic" alt="全年最低价!" src="<%=path %>/back/fbsp/viewPic/<%=picPath %>"></a>

<%}%>
中的src="<%=path %>/back/fbsp/viewPic/<%=picPath %>“。这段是输出图片用的，页面上加载10几个图，每个图在200k左右，是在页面没全部加载完时，又刷新页面造成的，不知道如何解决
