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
