@Autowired on a constructor of a Scala class

Question

I have a simple question, How could I use spring @Autowired on a constructor of this Scala class?

class MessageMBeanExporter(messageDirectory: MessageDirectory) extends MBeanExporter with SmartLifecycle {
      .....
}

Answer 1

I haven't tried it, but according to this and this link , from 2.8+ you could do:

class MessageMBeanExporter @Autowired() (messageDirectory: MessageDirectory) extends MBeanExporter with SmartLifecycle {
      .....
}

Answer 2

I've added support for @Autowired on the constructor of a Scala object into the spring-scala project. This is only (at time of writing) in the nightly snapshot.

This allows you to do

@Component
@Autowired
class Service(dep : Dependency) { }
