struts2 struts.xml提示找不到class

Question

struts2 struts.xml提示找不到class ,怎么办啊！

这是struts.xml

<?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>
	<package name="default" namespace="/" extends="struts-default">
		<action name="hello" class="com.imooc.test.Action.HelloAction" >
			<result>/index.jsp</result>
		</action>
	</package>
</struts>

这是Action

package com.imooc.test.Action;
import com.opensymphony.xwork2.ActionSupport;
public class HelloAction extends ActionSupport{
	@Override
	public String execute() throws Exception {
		System.out.println("Hello");
		return SUCCESS;
	}
}

这是报错信息
