getServletContext().getResourceAsStream() returns null

[gardellajuanpablo]

Hello team,

I'm using spring boot 2.0.1.RELEASE.

I'm migrating an application from spring (a WAR) to spring-boot. It uses GWT which uses a servlet that depends on getServletContext().getResourseAsStream() method works as expected.
I've make a reproducible project at
reproissue.zip

When doing a GET Request to http://localhost:8080/mymodule/afile.rpc you can see the file is returned, but if you execute http://localhost:8080/mymodule/dispatch a servlet is executed, the servlet uses getServletContext().getResourseAsStream() to return the same file, but null is returned in that case.

I saw similar issues filed before and marked solved, but maybe in spring boot 2.0.1 is failing again. Similar issues: #8525

Serving static resources from the classpath:static is a Spring MVC feature that is auto-configured by Spring Boot. The servlet container and servlet context know nothing about it is to be expected that the attempt to access the file via the servlet context does not work.

If you want static content to be served by the servlet container, you should place it in a location where the servlet container can find it. For example, in the root of an application packaged as a war file. If you require further guidance, please ask a question on Stack Overflow.

Yes thanks I finally solved using "classpath:/static" and by using classloader instead servlet context to find the file.
