File System Preferences Service Enhancement

[mwojno-tsg]

Overview

• The motivation enhancement came from a customer who was implementing a solr read only portal. They wanted user's to login to the portal and their user preferences to be saved.
• The generic preference service will still be wired up by default, however, an example bean will be commit as part of this on how to wire up the file system preference service.

Implementation

• Created new file FileSystemPreferencesService.java. Placed under com.tsgrp.opencontent.core.preferences
• Straight forward implementation reading and writing to the configuration location. The preferences will be stored under the user folder and the file name will be the user's login name.
• Removed unused attributes in core-defaults.properties : preferencesService.userPreferencesBasePath and preferencesService.userPreferencesRootPath

Closed with OC commit: 26862.

This commit updates the FileSystemPreferencesService with a couple small changes to resolve the issue of the first time a user needs a user pref file and there are other user's user pref files already created:

1. getObjectByPath helper function has a check to see if a directory is being retrieved or a file. If either doesn't exist, we need to create it.
2. The creation of an empty user preferences file has been extrapolated into a helper function as its now used in a couple places.
