OWNER, an API to ease Java property files usage.

Build Status Build Status Coverage Status

Built with Maven Powered by Sonar


The goal of OWNER API is to minimize the code required to handle application configuration through Java properties files.

Full documentation available on project website.


The approach used by OWNER APIs, is to define a Java interface associated to a properties file.

Suppose your properties file is defined as


To access this property you need to define a convenient Java interface in

public interface ServerConfig extends Config {
    int port();
    String hostname();
    int maxThreads();

We'll call this interface the Properties Mapping Interface or just Mapping Interface since its goal is to map Properties into a an easy to use piece of code.

Then, you can use it from inside your code:

public class MyApp {
    public static void main(String[] args) {
        ServerConfig cfg = ConfigFactory.create(ServerConfig.class);
        System.out.println("Server " + cfg.hostname() + ":" + cfg.port() +
                           " will run " + cfg.maxThreads());

But this is just the tip of the iceberg.
