PropertyUtils
Java Property utilities
Suffix and store properties for multiple environments in a single properties file, read them according to the current environment you are running.
Example:
# example property app.url
app.url-DEV=http://localhost:9002/
app.url-PROD=http://prod.herokuapp.com/
app.url-PREPROD=http://preprod.herokuapp.com/
# example property jdbcurl.driver
jdbcurl.driver-DEV=com.mysql.cj.jdbc.Driver
jdbcurl.driver-PROD=com.mysql.cj.jdbc.Driver
jdbcurl.driver-PREPROD=com.mysql.cj.jdbc.Driver
In production, you want to read the PROD suffixed properties from the file above, so you define an environmental variable like this:
java [other command line options] -DENVIRONMENT=PROD
In development, you want to read the DEV suffixed properties from the file above, so you define an environmental variable like this:
java [other command line options] -DENVIRONMENT=DEV
