Which two statements are correct when @SpringBootApplication is annotated on a class? (Choose two.)

Question

Options

• AIt causes Spring Boot to enable auto-configuration by default.
• BComponent scanning will start from the package of the class.
• CAll other annotations on the class will be ignored.
• DMethods in the class annotated with @Bean will be ignored.
• EA separate ApplicationContext will be created for each class annotated with

• A
  95% (20)
• C
  5% (1)

Explanation

@SpringBootApplication is a composite annotation that bundles @EnableAutoConfiguration, @SpringBootConfiguration, and @ComponentScan - so A is correct because @EnableAutoConfiguration triggers Spring Boot's auto-configuration mechanism, and B is correct because @ComponentScan defaults to scanning the package of the annotated class and its sub-packages.

C is wrong - other annotations on the class are not ignored; they are processed normally alongside @SpringBootApplication. D is wrong - @SpringBootConfiguration (included in the composite) marks the class as a configuration class, so @Bean methods are actively picked up and registered. E is wrong - Spring Boot creates a single ApplicationContext for the application, not one per annotated class; having multiple classes with @SpringBootApplication would be unusual and problematic.

Memory tip: Think of @SpringBootApplication as a "triple combo" (@EnableAutoConfiguration + @ComponentScan + @SpringBootConfiguration) - the first gives you auto-config (A), the second gives you component scanning from the current package (B), and the third makes @Bean methods work, which rules out both C and D.
