Order of injection when mixing constructor/setter injection (and even subclassing)

[David Nouls]

Hi,

 

I ran into a wall with GIN/Guice when it comes to mixing setter and constructor injection. I could not find any wiki page on the official guice page so I though I should ask the question here (before potentially creating an issue on gin or guice).

 

I have an object hierarchy that combines constructor injection and setter injection.

 

public class Base {

   @Inject Base( Something pDependency )

 

  @Inject setValidator( Validator validator ) {

 

  }

}

What is the question?

Is this what you're looking for: http://code.google.com/p/google-guice/wiki/InjectionPoints

Injections are performed in a specific order. All fields are injected and then all methods. Within the fields, supertype fields are injected before subtype fields. Similarly, supertype methods are injected before subtype methods.

Of course, constructors are injected before methods and fields, as you have to construct an instance before injecting its members.
