Hi all, Recently the topic of supporting autowiring of constructor parameters (IoC type 3) has come up a few times. I've taken a stab at implementing this in the BuilderFactory and it turns out to be rather easy. A few considerations and notes:
- The constructor autowiring would only kick in if there are no explicitly declared constructor parameters. Otherwise it could both prove complex to implement _and_ use. - All the constructor parameters have to be declared as interfaces. - If there are multiple constructors present BuilderFactory would chose the one with the highest number of parameters (greedy). Does this sound reasonable? I still have a few open issues I'd like to discuss: - Should there be an attribute on <construct> to explicitly enable or disable this constructor autowiring (e.g. "autowire-constructor")? IMO the BuilderFactory should be default autowire the constructor if there are no declared constructor parameters. This should work well for both the setter based _and_ constructor based dependency injection camps. - Should BuilderFactory report an error if there are multiple constructors which seem equally adequate (same number of parameters and a matching service for each)? --knut --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
