Description

Task List

  • Steps to reproduce provided
  • Stacktrace (if present) provided
  • Example that reproduces the problem uploaded to Github
  • Full description of the issue provided (see below)

Steps to Reproduce

  1. Create a file somefile.txt in src/main/resources/somedir.
  2. Inject the ResourceResolver.
  3. Call resourceResolver.getResource("classpath:somedir/")--> this returns Optional.empty but reference to directory expected.

Note that getting the somefile.txt resource directly via resourceResolver.getResource("classpath:somedir/somefile.txt") dies return the resource.

My current alternative is val dir = MyClass::class.java.getResource("/somedir/").

Expected Behaviour

ResourceResolver.getResource should return URI pointing to directory.

Actual Behaviour

Optional.empty returned.

Environment Information

  • Operating System: OSX
  • Micronaut Version: 1.0.1

Research direction
Investigate the current implementation of ResourceResolver in Micronaut core. The issue suggests that when a directory path is provided, getResource returns empty. Look at the class ResourceResolver and its getResource method to understand how it resolves classpath resources. Consider using Java's getResource() with trailing slash or using URLConnection to check if a resource is a directory. Check the 8 comments for any additional insights or proposed solutions.
