SpringBoot+jsp项目启动出现404

通过maven创建springboot项目启动出现404

application.properties配置
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
项目结构

控制器方法
package com.example.demo.controller;

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

@Controller
public class IndexController {

@RequestMapping(“/”)
public String index() {
return “index”;
}
}

启动项目访问localhost:8080，出现404
