Specify annotation values from property file ala Spring

[rquimosing]

It would be helpful if jcabi-aspects supported pulling data from property files in its annotations, similar to Spring:

@Value("${systemProperties.myValue}")

Ex:

@RetryOnFailure(attempts=${systemProperties.myMethod.attempts}, delay=${systemProperties.delay})

I have this specific use-case where I don't want to hardcode values in the annotation.

@yegor256 please pay attention to this issue

@rquimosing I have a different idea. How about we make it possible to specify negative values there:

package foo.pkg;
class Hello {
  @RetryOnFailure(attempts=-1, delay=-1)
  void sendMeSomewhere() {
  }
}

When such a value is found, jcabi will try to load these properties:

foo.pkg.Hello.sendMeSomewhere.attempts
foo.pkg.Hello.sendMeSomewhere.delay

What do you think?

Hi Yegor,

Sorry for the late reply, I got your email on the weekend and was out most of the time. Sure, that'll work. Although I went with a different approach for my original problem, I can revisit it and use your library. Let me know when it gets in the release version.

Thanks! Reggie

Hi yegor256,

I am starting to use your library and I came across with this suggestion regarding how to set the annotation values from a property. Have you included this feature in your latest release? Are you planning to include this in a next release?

Thanks
