JAVA_WEB Struts2学习：Struts2Ajax标签的学习
导入Struts2 Ajax标签：
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<%@ taglib uri="/struts-tags" prefix="s" %>
<%@ taglib uri="/struts-dojo-tags" prefix="sx" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
Struts2 Ajax标签 实例1：
index：
