使用Struts Tags 需要在jsp页面中加入下面一行。
<%@ taglib prefix="s" uri="/struts-tags" %>
15.2.1. property
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Hello</title>
</head>
<body>
Hello, <s:property value="name"/>
</body>
</html>
<s:property value="messageStore.message" /> <s:property value="#session.user.username" /> <s:bean name="cn.netkiller.Person" var="personBean" /> <s:property value="#personBean.name" />
15.2.2. set
<s:set var="personName" value="person.name"/> Hello, <s:property value="#personName"/> <s:set var="janesName">Jane Doe</s:set> <s:property value="#janesName"/>
禁止HTML转义，如果你的字符串中含有&, <, > 等字符输出就会出现 &, <, > escapeHtml="false" 可以禁止这样的转义，原样输出。
<s:property value="url" escapeHtml="false"/>
