On the difference between @Autowired, @Inject and @Resource you can look here. Here you can thorough description and comparison.

What concerns the first difference: @Configuration is used as replacement for XML-based configuration, ie. it marks classes as the ones used for Java-based configuration, see here. In turn, @Component is actually used to mark classes as the ones to be instantiated by Spring and @Configuration is meta-annotated by @Component annotation.

@Component and @Configuration serve different purposes so it doesn't make sense to compare them.
