Difference between Spring annotations

Question

Questions:

1) Difference between @Component and @Configuration?

I have read that both remove the necessity of

Answer 1

In most the answers above, users suggest to say that @Component and @ Configuration serve different purposes. But I do not see it happening in reality.

But I have a simple Spring MVC application.

@Configuration
    public class SpringConfiguration {

@Bean
public  InternalResourceViewResolver initViewResolver(){
    InternalResourceViewResolver x = new InternalResourceViewResolver();
    x.setPrefix("/WEB-INF/jsp/");
    x.setSuffix(".jsp");
    return x;
}

}

This main class works fine even if it is annotated as @Component instead of @Configuration.

Similarly inside a class annotated as @Component if you have methods annotated with @Bean, those beans are created when context is loaed.

So I think, it is just for code readability that we should mark main configuration class as @Configuration and other classes with @Component. Actual execution wise there seems no difference.
