Difference between @Bean and @Named

Question

I'm working on a class that has the following:

@Bean(name = "pluto")
public Z potato (...) {
    ...
}

@Bean(name = "mars") 
public carrot (@Named("pluto") Z z) {
    ...
}

I'd like to know if @Bean and @Named are interchangeable.

Also, why is @Named being used in the parameter?

@Makoto, @Named annotation in Spring MVC is similar but the answer here seems to be

@Named and @Bean are equivalent, but are from different APIs. So only use @Named for consistency
