但是看了提示的那个位置，写的是：
没发现有什么错误！
HelloAction.java:
package com.itheima.web.action;
/**
- Struts2入门案例
- @author root
*
/
public class HelloAction {
/*
- 在动作类中制定的动作方法
- 动作方法的书写要求：
- １．都是ｐｕｂｌｉｃ的
- ２．返回值必须是Ｓｔｒｉｎｇ
- ３．必须没有参数
- @return */ public String sayHello() { System.out.println("sayHello，方法执行了！"); return "success"; }
}
