Static file server seems to not work when accessed via `/vaadinServlet`

[fluorumlabs]

Steps to reproduce:

1. Generate Spring Boot-based SVC project
2. Start application
3. Navigate to http://localhost:8080/vaadinServlet
4. Observe that the image in the app layout is not shown: request to http://localhost:8888/vaadinServlet/images/logo.png returns HTML.

Hi @fluorumlabs ,

could you please tell which version of Vaadin have you chosen?

Thanks,

[fluorumlabs]

I've been testing with Vaadin 20.0.0.beta1 / Flow 7.0.0.beta3

[miguelatvaadin]

I understand that it is related to #802, when using VaadinWebSecurityConfigurerAdapter

[fluorumlabs]

It's not related to Spring Security.

1. Open https://labs.vaadin.com/edit-multiple/vaadinServlet/
2. Observe "broken" image in the top left corner
3. Image URL is https://labs.vaadin.com/edit-multiple/vaadinServlet/images/logo.png

Ok. Great. Thanks for point it out, @fluorumlabs.

So, when accessing the vaadin servlet directly (as it is published at /vaadinServlet by the spring plugin) to serve the app it is not serving the static content as it is not recognized as a static resource.

Removing the servlet path when calling getStaticResource inside StaticFileServer#isStaticResourceRequest would solve the issue.

The described behavior is the same for V14

To be re-tested with latest Vaadin version (23.2).

Why should this work? /vaadinServlet/ should preferrably not even be available for direct use
