springfox-swagger-ui 2.9.2未显示swagger-ui.html页面返回404

Question

Iam使用spring boot版本2.2.0.M3和spring-fox 2.9.2。 问题是，当我访问时，iam能够查看swagger json

arr[4]

但是当我访问时，我无法看到摇摇欲坠的UI屏幕

 http://localhost:8080/api/v2/api-docs

使我能够在没有上下文路径的情况下从另一个项目中看到swagger-ui.html。

 http://localhost:8080/api/swagger-ui.html

在我的application.properties中已设置

 http://localhost:8080/swagger-ui.html

我的pom.xml

 server.servlet.context-path =/api
