我刚刚下载了这个项目：
https://github.com/oktadeveloper/okta-spring-boot-2-angular-5-example https://github.com/oktadeveloper/okta-spring-boot-2-angular-5-example
本教程中对此进行了解释：
https://developer.okta.com/blog/2017/12/04/basic-crud-angular-and-spring-boot https://developer.okta.com/blog/2017/12/04/basic-crud-angular-and-spring-boot
但是当我尝试使用推荐的命令运行服务器时：
./mvnw spring-boot:run
我得到以下输出：
David@HP /cygdrive/d/wamp64/www/external/okta.example.com/server
$ ./mvnw spring-boot:run

正如你所看到的，有一行这样写：

关于如何使服务器工作有什么想法吗？
Thanks!
