What are the best practices for using Spring annotations?

When using Spring annotations, it's best to keep your code clean and maintainable. Use annotations like @Autowired for dependency injection, but avoid overusing them to prevent tight coupling.

Can you give examples of common annotations?

Sure! Common Spring annotations include @Component, @Service, @Repository, and @Controller. Each serves a specific purpose in the application context.

How do I decide which annotation to use?

Choose annotations based on the role of the class. For example, use @Service for service layer classes and @Repository for data access classes to enhance clarity.

Are there any performance considerations?

Yes, excessive use of annotations can lead to performance overhead. It's important to balance convenience with performance by not over-annotating.

What about custom annotations?

Custom annotations can be useful for encapsulating common behaviors. Just ensure they are well-documented and used consistently.
