I am trying to figure out if commons-configuration currently provides a
means to specify a folder and load all property files into
configuration. For example, I currently have the following:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<override>
<system />
<properties fileName="/properties/propertyFile.properties"
throwExceptionOnMissing="false" config-name="override"
config-optional="true" />
....
and would be interested in having something like:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<override>
<system />
<properties fileName="/properties/*.properties"
throwExceptionOnMissing="false" config-name="override"
config-optional="true" />
....
Is there currently a way to do this? If not, what class\classes would
you recommend extending in order to provide this sort of functionality?
Unfortunately, this is not supported so far. I had also thought about a
feature like scanning a directory and collecting all configuration files
found. This would be a nice enhancement for [configuration].
For the implementation I would probably use DefaultConfigurationBuilder.
You can write a simple directory scanner class that adds all
configuration files it detects to a DefaultConfigurationBuilder
instance. Because DefaultConfigurationBuilder extends XMLConfiguration
you can simulate the structure of a configuration definition file with
corresponding addProperty() calls (I think the unit tests in
TestDefaultConfigurationBuilder do similar things). After the
DefaultConfigurationBuilder instance has been initialized you can obtain
a combined configuration object from it.
