原文链接：http://wl-ldy.iteye.com/blog/858278

1.s:generator标签概述

属性名	是否必须	类型	说明
converter	False	org.apache.struts2.util.IteratorGeneratorConverter	将字符串转换为Object对象的类实例
count	False	Integer	指定最大分割的数量
separator	True	String	指定分隔符
val	True	String	指定要分割的字符串
var	False	String	将结果放到Page上下文中

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>
