本文介绍Struts2框架中generator标签的使用方法，并通过一个具体示例展示了如何利用该标签来处理字符串分割和迭代显示。示例包括Action类定义、JSP页面配置及struts.xml文件设置。

package com.wl.control.tagsAction;

import com.opensymphony.xwork2.ActionSupport;

public class ShowGeneratorList extends ActionSupport {

    private String nameList="张三,李四,王五";

    public String getNameList() {
        return nameList;
    }

    public void setNameList(String nameList) {
        this.nameList = nameList;
    }

    @Override
    public String execute() throws Exception {

        return "showgeneratorlist";
    }

}

3.新建JSP文件

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%@ taglib uri="/struts-tags" prefix="s" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>

  <body>
     <s:generator separator="," val="nameList">
        <s:iterator>
           <s:property/>
           <br/>
        </s:iterator>
     </s:generator>
  </body>
</html>

4.修改struts.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC 
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
   <package name="Struts2.1" extends="struts-default">
       <action name="showgeneratorlist" class="com.wl.control.tagsAction.ShowGeneratorList">
           <result name="showgeneratorlist">/controlTags/showgeneratorlist.jsp</result>
       </action>
   </package>
</struts>

5.运行结果：
