Web.servlet.PageNotFound - 没有 GET 映射-解网

问：

我正在学习Spring boot + MVC的工作原理。我可以在屏幕上显示消息，但无法修改样式。js e css 文件不与 Spring 映射。

2020-04-17 14:38:29.169  WARN 9552 --- [nio-8080-exec-3] o.s.web.servlet.PageNotFound             : No mapping for GET /js/main.js

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;

@Controller
public class HelloController {

     @GetMapping("/")
        public String index() {
            return "index";
        }

        @PostMapping("/hello") 
        public String sayhello(@RequestParam("name") String name, Model model) {
            model.addAttribute("name", name);
            return "hello";
        }

        @GetMapping({"/helloworld", "/helloname"})
        public String hello(Model model, @RequestParam(value="name", required=false, defaultValue="WORLD") String name) {
            model.addAttribute("name", name);
            return "helloname";
        }
}

我尝试修改application.properties中的路径，但它没有改变任何东西。

spring.mvc.view.prefix = /WEB-INF/view/
spring.mvc.view.suffix = .jsp
spring.mvc.static-path-pattern = /resources/**

这是我的jsp页面。当我运行此页面时，我收到之前发布过的错误消息
