Spring bean classes are defined under a package called com.mycomp.service. What two options are required to enable component scanning? (Choose two.)

Question

Options

• AEnsure bean classes are annotated with the @Component annotation.
• BAdd the @ComponentScan ("com.mycomp. service") to the Java configuration.
• CEnsure bean classes are annotated with the @Autowired annotation.
• DEnsure bean classes are annotated with the @Bean annotation.
• EEnsure bean classes are annotated with the @ComponentScan annotation.

• A

• C

• D

• E

Explanation

For Spring to automatically discover and register beans via component scanning, two things must work together: the bean classes must be marked with @Component (or a stereotype like @Service, @Repository) so Spring recognizes them as candidates (A), and the configuration class must include @ComponentScan("com.mycomp.service") to tell Spring where to look (B) - without the package path, Spring won't know which packages to scan.

Why the distractors are wrong:

• C - @Autowired is for injecting dependencies into a bean, not for declaring it as a bean.
• D - @Bean is used on methods inside a @Configuration class to manually define beans; it's not placed on bean classes themselves and has nothing to do with component scanning.
• E - @ComponentScan belongs on the configuration class, not on individual bean classes; placing it on a bean class would have no effect.

Memory tip: Think of it as a two-sided contract - the beans raise their hand with @Component ("I'm here!"), and the config class uses @ComponentScan("package") to know which room to look in. Both sides must do their part.
