Answer 1

You should use java.util.Properties to access external file, refer to this answer to load xml properties file

Answer 2

In your property file try:

external.config=D:/DEV//X/X1/Service/target/conf/rConfiguration.xml

Or annotate your configuration file with following

@configuration @ImportResource("D:/DEV//X/X1/Service/target/conf/rConfiguration.xml")
