As of Spring Framework 4.3, an @Autowired annotation on such a constructor is no longer necessary if the target bean only defines one constructor to begin with. However, if several constructors are available, at least one must be annotated to teach the container which one to use.

Lombok can create a constructor with required arguments. Required arguments are final fields and fields with constraints such as @NonNull.

I have read at few places where it suggest not to use @Autowired on fields. Instead constructor injection is preferred
