Hello everyone,
I have `Module module`. If this module is automatic I need to get the list of all its services/providers, so,
as I understand the only way to do it is to read its META-INF/services folder. I tried:
if (module.getDescriptor().isAutomatic()) {
ClassLoader classLoader = module.getClassLoader();
Enumeration<URL> resources = classLoader.getResources("META-INF/services/");
while (resources.hasMoreElements()) {
URL resource = resources.nextElement();
...
}
}
but it doesn't work. All `resource`s have same path ending in `....META-INF/service`.
I tried:
ModuleReference reference = ... ;
var entries = reference.open().list().collect(Collectors.toList());
It worked, but I need only one folder, but not all with all classes etc. Could
anyone what is the optimal way to do it?
In your second attempt then you course add a filter it to just the
resources with names that start with META-INF/services.
In any case, I assume the method you are looking for is
ModuleDescriptor::provides. It returns the set of Provides objects for
service providers in the module (it doesn't matter than the module is an
automatic module).
