Archivos properties con Producer

A veces podemos crear @Producer para obtener los valores del archivo de propiedades

crear el archivo en /src/main/resources

Leer el archivo

 InputStream inputStream = getClass()
                        .getClassLoader().getResourceAsStream("connection.properties");
                Properties prop = new Properties();

                if (inputStream != null) {

                    prop.load(inputStream);
                    String ip = prop.getProperty("ip");
                    Integer port = Integer.parseInt(prop.getProperty("port"));
                    String user = prop.getProperty("user");
                    String password = prop.getProperty("password");
