为什么我的struts2标检没法生成form表单的action值.


<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<html>
<head>
<title>My JSP 'index.jsp' starting page</title>
</head> <body>
<s:url action='person' namespace='/person' />
<br />
<s:form action="person" namespace="/person" method="post"> <s:textfield name="person.name"></s:textfield>
<br />
<s:radio name="person.gender" list="#{'MAN':'男','WOMAN':'女'}"
listKey="key" listValue="value"></s:radio>
<br />
<s:submit value="保存"></s:submit>
</s:form>
</body>
</html>所生成的源代码:
<html>
<head>
<title>My JSP 'index.jsp' starting page</title>
</head> <body>
/ssh/person/person.do
<br />
<form id="person" name="person" action="person" method="post"> <input type="text" name="person.name" value="" id="person_person_name"/>
<br />
<input type="radio" name="person.gender" id="person_person_genderMAN" value="MAN"/><label for="person_person_genderMAN">男</label>
<input type="radio" name="person.gender" id="person_person_genderWOMAN" value="WOMAN"/><label for="person_person_genderWOMAN">女</label> <br />
