Using Google Guice to inject java properties

Question

I want to use google guice to make properties available in all classes of my application. I defined a Module which loads and binds the properties file Test.properties.<

Answer 1

The library Guice configuration can inject for you values from Properties or JSON files to your services.

You can inject from the file application.properties to your service as :

@BindConfig(value = "application", syntax = PROPERTIES)
public class Service {

    @InjectConfig
    private int port;

    @InjectConfig
    private String url;

    @InjectConfig
    private Optional timeout;
}

You must simply install the modules ConfigurationModule

public class GuiceModule extends AbstractModule {
    @Override
    protected void configure() {
        install(ConfigurationModule.create());
        requestInjection(Service.class);
    }
}
