I took the lazy way out and copied the FilesystemResourceLocator code to
create my own non-deprecated version of it. ;-)

Thank you John. This seems like a lot of work for something that
seems to work so simply now and is easy to read/implement in one line
of code.
Does the FilesystemResourceLocator really need to be removed? It
seems like a very nice "helper" object to me.

You'll have to subclass ResourceLocator and implement it:
/**
* Finds a collection of matching resources for a given name.
The name
components must
* be separated by forward slashes.
*/
Collection<Resource> findResources(String name);
For example, The name portion could just be the file name
"cayenne-blah.xml", and your subclass could hardcode the directory path.
The logic could be copied from FilesystemResourceLocator:
File resourceFile = *new* File(root, name);
*if* (resourceFile.exists()) {
*try* {
resources.add(*new* URLResource(resourceFile
.toURI().toURL()));
}
*catch* (MalformedURLException e) {
*throw* *new* CayenneRuntimeException("Can't
convert
file to URL: %s", e, resourceFile.getAbsolutePath());
}
}
Binding it using DI looks like this:
// a locator of resources, such as XML descriptors
binder.bind(ResourceLocator.*class*).to(MyResourceLocator.*class*);
binder.bind(Key.*get*(ResourceLocator.*class*, Constants.
*SERVER_RESOURCE_LOCATOR*)).to(MyResourceLocator.*class*);

I have hopefully a quick question on how Cayenne can be configured to
use a configuration file outside of a JAR/WAR.
I currently use this to reference an absolute file path for my Cayenne
files but I see that FilesystemResourceLocator is now deprecated ...
Module myModule = (org.apache.cayenne.di.Binder
binder) -> {
binder.bind(ResourceLocator.class).toInstance(new
FilesystemResourceLocator(filePathForCayenne));
...
What is the "new" way to replicate the same functionality. The
deprecated notes just provide the same example I'm already using.
Thanks,
Andrew
