**一 pojo类**

package org.crazyit.app.dto;
    
    
    public class Person
    {
        private String name;
        private int age;
    
        // name的setter和getter方法
        public void setName(String name)
        {
            this.name = name;
        }
        public String getName()
        {
            return this.name;
        }
    
        // age的setter和getter方法
        public void setAge(int age)
        {
            this.age = age;
        }
        public int getAge()
        {
            return this.age;
        }
    }

**二 视图**

1 s-bean.jsp

<%@ page contentType="text/html; charset=GBK" language="java" errorPage="" %>
    <%@taglib prefix="s" uri="/struts-tags"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title>使用s:bean标签创建JavaBean的实例</title>
    </head>
    <body>
    
    <s:bean name="org.crazyit.app.dto.Person">
        
        <s:param name="name" value="'yeeku'"/>
        <s:param name="age" value="29"/>
        
        Person实例的name为：<s:property value="name"/><br/>
        Person实例的age为：<s:property value="age"/>
    </s:bean>
    </body>
    </html>

2 s-bean-var.jsp

<%@ page contentType="text/html; charset=GBK" language="java" errorPage="" %>
    <%@taglib prefix="s" uri="/struts-tags"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title>使用s:bean标签创建JavaBean的实例</title>
    </head>
    <body>
    
    <s:bean name="org.crazyit.app.dto.Person" var="p">
        
        <s:param name="name" value="'yeeku'"/>
        <s:param name="age" value="29"/>
    </s:bean>
    
    Person实例的name为：<s:property value="#p.name"/><br/>
    Person实例的age为：<s:property value="#p.age"/><br/>
    ${requestScope.p}
    </body>
    </html>
