Spring boot application shows file download option when serving static content

I have a spring boot application in which I have some static files kept inside resources/static directory. One of them is a swagger directory. The file system layout looks as follows:

resources
- static
  - swagger
    - index.html

Now if I send request to my webapp with URI localhost:8080/swagger/index.html then it serves the file correctly. However, if I send request to localhost:8080/swagger then the webapp shows a file download box with an empty binary file named swagger.

In my opinion second URI should actually serve the index.html file automatically. How do I fix this behavior?
