Struts2的<s:property>标签是用来从一个类获得属性值，如果没有指定，这将默认为当前Action类(堆栈的顶部)属性。
1. 动作类
这里有一个Action类，有一个 name 属性。
PropertyTagAction.java
package com.bdqn.smfy;
import com.opensymphony.xwork2.ActionSupport;
public class PropertyTagAction extends ActionSupport{
private String name = "Name from PropertyTagAction.java";
public String getName() {
return name;
}
public String execute() throws Exception {
return SUCCESS;
}
}2. Bean
一个简单的Java类，它有一个 name 属性。
Person.java
package com.bdqn.smfy;
public class Person {
private String name = "Name from Person.java";
public String getName() {
return name;
}
}3. 在jsp页面上使用<s:property>标签
展示了如何使用<s:property>标签，从PropertyTagAction与“Person”类获得name属性值。
property.jsp
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
</head>
<body>
<h1>Struts 2 property tag example</h1>
<h2>1. Call getName() from propertyTagAction.java</h2>
<s:property value="name" />
<h2>2. Call getName() from Person.java</h2>
<s:bean name="com.bdqn.smfy.Person" var="personBean" />
<s:property value="#personBean.name" />
</body>
</html> 4. struts.xml
