What are the differences between Spring annotations and Java annotations?

What are the differences between Spring annotations and Java annotations?

Spring annotations are specific to the Spring framework and provide additional functionality, while Java annotations are part of the Java language itself and serve as metadata.

Can you give me examples of both types of annotations?

Sure! An example of a Java annotation is @Override, which indicates that a method overrides a superclass method. A Spring annotation example is @Autowired, which is used for dependency injection.

How do Spring annotations enhance Java annotations?

Spring annotations build on Java annotations by adding features like configuration, lifecycle management, and aspect-oriented programming, making them more powerful in a Spring context.

Are there any performance implications when using Spring annotations?

Generally, the performance impact is minimal, but improper use of annotations can lead to overhead, especially in large applications.
