All that's actually necessary is that you define your object as a class, rather than an object. That way Spring will instantiate it.

 @Service

        val userRepository: UserRepository = null;

        .....
    }

         .....
         
              
              
         
    

Changing the "val" to "var" is unnecessary (Spring uses reflection, which ignores immutability). I'm pretty sure that that @BeanProperty is also unnecessary (Spring will assign to the underlying field, reflectively).
