  </welcome-file-list>
</web-app>

2.struts.xml 配置


<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>
	<!--==================== -->
	<!--=====定义常量========= -->
	<!--==================== -->

	<!-- 修改请求的后缀名为.do 修改后每个请求必须要有后缀了-->
	<constant name="struts.action.extension" value="do,action"/>

	<!-- 默认的视图主题 <constant name="struts.ui.theme" value="simple"/>-->
	<!--+===================+-->
	<!--+=====定义基本包=======+-->
	<!--+===================+-->
	<package name="default" extends="struts-default">
		<action name="showPerson" class="com.luob.action.ShowPerson">
			<result name="success">/showPerson.jsp</result>
		</action>
	</package>

</struts>

3.Action


package com.luob.action;

import com.luob.model.Person;
import com.opensymphony.xwork2.ActionSupport;

public class ShowPerson extends ActionSupport {

	private Person person;  //采用POJO的方式进行赋值和存值

	@Override
	public String execute() throws Exception {
		// TODO Auto-generated method stub
		return SUCCESS;
	}
	public Person getPerson() {
		return person;
	}
	public void setPerson(Person person) {
		this.person = person;
	}

}

4.POJO 对象


package com.luob.model;

public class Person {
	private String name;
	private String sex;
	private String age;
	private String address;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {
		this.sex = sex;
	}
	public String getAge() {
		return age;
	}
	public void setAge(String age) {
		this.age = age;
	}
	public String getAddress() {
		return address;
	}
	public void setAddress(String address) {
		this.address = address;
	}

}

6.赋值jsp页面


  <body>
   <center>
   	<s:form action="showPerson" method="post">
   		<s:textfield name="person.name" label="姓名"/>
   		<s:textfield name="person.sex"  label="性别"/>
   		<s:textfield name="person.age" label="年龄"/>
   		<s:textfield name="person.address" label="住址"/>
   		<s:submit value="提交"/>
   	</s:form>
   </center>
  </body>

7.取值jsp页面


<body>
   	<center>
   		<h3>使用POJO</h3><br/>
   		<hr>
   		姓名：${person.name}
   		性别：${person.sex}
   		年龄：${person.age}
   		地址：${person.address}
   	</center>
  </body>
