converterFalseorg.apache.struts2.util.IteratorGeneratorConverter将字符串转换为Object对象的类实例
countFalseInteger指定最大分割的数量

2.新建Action实例 
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>
