SpringBoot+jsp项目启动出现404的解决方法

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

whitelabel error page
this application has no explicit mapping for /error, so you are seeing this as a fallback.
