2> 配置struts.xml配置文件

☞ 注意：classpath同級目錄下

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
	"http://struts.apache.org/dtds/struts-2.5.dtd">
	
<struts>
	<package name="p1" extends="struts-default">
		<action name="hello" class="xyz.kuoa.web.action.HelloAction.Hello" method="sayHello">
			<result>/page/success.jsp</result>
		</action>
	</package>
</struts>

3> 處理Action

package xyz.kuoa.web.action.HelloAction;

public class Hello {
	
	public String sayHello() {
		System.out.println("Hello Struts!");
		return "success";
	}
	
}
