spring @Autowire property vs setter

Question

What is the difference between anotate @Autowired to a property or do it in the setter?

As far as I know they both have the same result, but is there any reason to use o

Answer 1

If you can, you should avoid the setter. If you don't need it, it's better when it doesn't exists, right?

I personally prefer Guice allowing me to write

public class TextEditor {
   private final SpellChecker spellChecker;

   @Inject public TextEditor(SpellChecker spellChecker) {
      this.spellChecker = spellChecker;
   }

   public void spellCheck(){
      spellChecker.checkSpelling();
   }
}

This goes a step further: With a final field, I know it won't ever change and I get the multithreading visibility guarantee.
