mvc 扫描jar jsp_SpringBoot+jsp项目启动出现404

通过maven创建springboot项目启动出现404

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;@Controllerpublic class IndexController {@RequestMapping("/")public String index() {return "index";}}

启动项目访问localhost:8080，出现404

Whitelabel Error PageThis application has no explicit mapping for /error, so you are seeing this as a fallback.Thu Feb 28 22:59:29 CST There was an unexpected error (type=Not Found, status=404).No message available

解决方法

<dependency><groupId>org.apache.tomcat.embed</groupId><artifactId>tomcat-embed-jasper</artifactId></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId></dependency>

clean并刷新maven重启并访问localhost:8080

打包为jar运行仍然出现404
