Spring constructor dependency injection: Java vs. Kotlin

Sample.java

// With Java, it's a lot of boilerplate code if you want to do it right and have your dependencies
// injected via the constructor instead of annotating private variables.
// see also: http://olivergierke.de/2013/11/why-field-injection-is-evil/

@Component
public class Sample {
  private SomeDependency someDependency;

  @Autowired
  public Sample(SomeDependency someDependency) {
    Assert.notNull(someDependency, "someDependency must not be null");
    this.someDependency = someDependency;
  }
  
}

Sample.kt

// With Kotlin, you can have it with no boilerplate at all.
@Component
open class Sample @Autowired (val someDependency:SomeDependency) {
}

or:
@component
open class Sample @Autowired constructor(val someDependency:SomeDependency) {
}

As mentioned here, both @Autowired and constructor can be dropped with the use @component and thus making the code even better and neat :
@component
open class Sample (val someDependency:SomeDependency) {
}

Thanks!
