How to retrieve/inject the value of a single parameter from the YAML config file

[Vadim Oglinda]

I can't figure out what is the mechanism to retrieve / inject the value of a single root level parameter from the config yml file without using the ConfigurationFactory.

say the only thing in the config file is just:

param1: value1

I want to use value1 within a @Provides method to construct an object.

Thanks.

Hi Vadim,

Bootique somewhat intentionally doesn't provide explicit API for property access, steering the user towards writing factory objects. Though, as you said, in some cases this may be a valuable shortcut. And you can do with the existing methods. You'd still need a ConfigurationFactory though, as this is the object that stores the configuration tree. So it is the source of this data. And then you can retrieve the value as e.g. a String, using "param1" as a root prefix:


@Provides
@Singleton
MyService provideMyService(ConfigurationFactory cf) {
String value = cf.config(String.class, "param1");
...
}

HTH,
