Look for all property files with the given name (e.g.
|
public static final int CONFIGURATION_ORDINAL_DEFAULT_VALUE
public static final String CONFIGURATION_ORDINAL_PROPERTY_NAME
public static Properties getProperties(String propertyFileName)
Look for all property files with the given name (e.g. 'myconfig.properties') in the classpath. Then load all properties files and sort them by their ascending configuration order and apply them in this order.
The idea is to be able to 'override' properties by just providing a new properties file with the same name but a higher 'configuration.ordinal' than the old one.
If a property file defines no 'configuration.ordinal' property than a default
value of CONFIGURATION_ORDINAL_DEFAULT_VALUE
is assumed. Any sensitive
default which is provided by the system parsing for the configuration should
have a 'configuration.ordinal' value lower than 10. In most cases a value of 1
If 2 property files have the same ordinal 'configuraiton.order' the outcome is not really defined. The Properties file which got found first will be processed first and thus get overwritten by the one found later.
