Springboot項目啟動，IDE的控制台報錯信息：
Unable to infer base url. This is common when using dynamic servlet registration or when the API is behind an API Gateway.
The base url is the root of where all the swagger resources are served. For e.g. if the api is available at http://example.org/api/v2/api-docs then the base url is http://example.org/api/.
Please enter the location manually；
可能是啟動類缺少注解@EnableSwagger2
