Whats the difference between @Bean and @Component annotation in springboot? I am confused when do we use @Component and @Bean.

Whats the difference between @Bean and @Component annotation in springboot? I am confused when do we use @Component and @Bean.

@Bean and @Component are both annotations used in Spring to manage beans.

• @Bean is used to explicitly declare a single bean in a configuration class method, allowing for customization of the bean creation process.
• @Component is a generic stereotype annotation that can be applied to any class, marking it as a Spring component.

Use @Component when you want Spring to automatically detect and register the bean. Use @Bean when you need more control over the bean configuration.

@Component and its meta-annotated annotations are used on top of a class
@Bean is used on @Configuration classes

it is basically the difference between Java-based and Annotation-based Container Configuration

cant we use them interchangeably? since their primary purpose is to create bean

[bitter sluice]

you can, with @Component Spring automatically finds @Autowired constructors and uses them

with @Bean methods you are still responsible for doing new MyBean(...)
