提交form表单action代码执行两次?!!!!!!!是struts2
问题很奇怪,测了下是在最后的form表单(句号那),只要迭代从后台传来的list的值就会让action代码执行两次

HTML code
<%@ page language="java" import="com.sykjw.entity.*,java.util.*,com.sykjw.vo.BasketFee" pageEncoding="utf-8"%>

<%@ taglib uri="/struts-tags" prefix="s" %>

<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
