The idea behind moka is to provide a way to override property file defaults with environment variables passed to the application.
For instance, take this example property file:
my.property=defaultfordev
And say its located under src/java/resources/config called app.properties.
In your java code you would init your config with moka via:
Configuration config = new Configuration("app");
config.addLoadPath("/config");
config.init();
And at runtime if you wanted to override the value with an environment variable you would run export MY_PROPERTY=propertyforprod.
This would override the property value with propertyforprod.
To get this property in your code you would use:
config.getString("my.property");
In addition to environment variable overrides it supports system property eg (-Dmy.property=blah) overrides.
The supported property values are:
- Integer -
config.getInteger("my.int")this would parse a string into an integer - String -
config.getString("my.str") - String Array -
config.getStringArray("my.stringarr")this would parse a comma delimited string value into a string array
