OWNER, an API to ease Java property files usage.
- Maven (tested with 3.1.1, older/newer versions should also work)
Run 'mvn -npr eclipse:eclipse'.
This fork was created to implement YAML loading/parsing into OWNER. To do so, we sadly had to let go of some features that we didn't need and didn't have time to port:
- XML configurations are not supported anymore. '.properties' should still work but are not used outside of the unit tests.
- Accessible interface does not have the 'store' method anymore since it's currently impossible to know which format the properties should be saved as. This sadly break a lot of unit tests that relied on properties being able to be saved at runtime :(
- Documentation outdated in some places (Should not really impact users of the library though).
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 ServerConfig.properties
:
port=80
hostname=foobar.com
maxThreads=100
To access this property you need to define a convenient Java
interface in ServerConfig.java
:
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.
