For injection, setter and constructor should be public ?

[3rdstage]

Simple question

Should setter or constructor be public for dependency injection ?

It seems to be doubtless, but is not explicitly stated anywhere in reference manual.
Why don't you clarify that in reference manual.

Constructors can be anything, spring uses reflection for that so you could go with private constructors. The setters have to be public, we use the normal Property stuff which ships with the JDK.
