springboot访问页面显示Whitelabel Error Page

新建springboot（2.5.7版本）项目配置好mvc，访问页面显示Whitelabel Error Page

@Controller
public class LoginController {
    @Autowired
    private LoginService loginService;

    @RequestMapping("/login")
    public String login(){
        System.out.println("访问");
        return "login";
    }
}

server:
  port: 8080
  servlet:
    context-path: /
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/test?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf8&autoReconnect=true&allowMultiQueries=true
    username: root
    password: root
  mvc:
    view:
      prefix: /views/
      suffix: .html

配置文件添加

spring:
  resources:
    static-locations: classpath:/templates

默认Springboot会从static目录加载前端静态资源，我的项目页面写在了templates目录下，通过配置static-locations参数或直接把页面放入static目录下都可以解决问题。
