How do I exclude all @Component classes except for one under @ComponentScan?

Question

I have the following annotation in my code:

@ComponentScan(basePackageClasses={MyClass.class},
            excludeFilters={@Filter(Component.class)}, //@Component
            includeFilters={@Filter(type=ASSIGNABLE_TYPE, classes=MyClass.class)}
        )

MyClass is annotated with @Component but still want to include it during component scan. However, component scan filters seem to use and logic instead of or. How do I achieve what I want to do?

@M.Deinum Can you please turn your comment into an answer so that I can accept it. Also mention that there's `useDefaultFilters` attribute under `@ComponentScan`. — Psycho Punch, Aug 02 '16 at 14:35
This is a dumb question but if you're only including a single class, why use `@ComponentScan` at all? — Miloš Milivojević, Aug 02 '16 at 14:53
@MilošMilivojević because it's not actually just one class from one package. It's just a cross-section of the actual problem. — Psycho Punch, Aug 02 '16 at 14:57

@Configuration is more deterministic than @ComponentScan at all cases.

Rather than workarounding the @ComponentScan annotation. You should try to explicitly list your MyClass.class in a @Configuration class as a @Bean, like:

@Configuration
public class MyClassConfiguraiton {

    @Bean
    public MyClass myClass() {
        return new MyClass();
    }
}

Then @Import the configuration class explicitly instead of the @ComponentScan annotation:

@Import(MyClassConfiguratrion.class)

Or import it via component scan mechanism (since @Configuration is meta-annotated with @Component).
