'using requestmapping annotation to request page

I am using eclipse to write some spring MVC project, but my project can't find the variable of requestmapping I gave. so I write some test controller to display my test.jsp

controller.java

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping("/")
public class test{
    @RequestMapping(value="test",method={RequestMethod.GET})
    public String test() {
        return "test";
    }
}

test.jsp

<%@ page language="java" contentType="text/html; charset=BIG5"
    pageEncoding="BIG5"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="BIG5">
<title>Insert title here</title>
</head>
<body>
    <h6>hello world!</h6>
</body>
</html>

Sadly,no matter how I've tried,my tomcat server just can't find the page by using the path http://localhost:(port)/(projectname)/test

Eclipse version also confused me.I used to put my jsp beneath the webcontent/web-inf in old version of eclipse.However,after updating my eclipse to 2021-06 ,I'm not surely understand where should I put my jsp to enable my controller can get use of it.

I've found if I just put my jsp under my webapp folder,I could use absolute path to get my jsp

http://localhost:8080/acqdemo/test.jsp

However, It might no longer be as Spring MVC Framework anymore.Sorry to ask this simple question. I'm a newbie of java spring, and I just hope anyone can help me solve this problem.

btw this is my web.xml

<?xml version="1.0" encoding="UTF-8"?>

        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:servlet-context.xml</param-value>
        </init-param>

    </servlet>
  <absolute-ordering />
</web-app>
