Understanding Spring's @Configuration Annotation

Hey everyone! 👋 Today, I want to dive into the @Configuration annotation in Spring Framework, which is crucial for defining beans in your application.

🛠️ What is @Configuration?
- It's a class-level annotation that indicates that the class can be used by the Spring IoC container as a source of bean definitions.
- With @Configuration, you can define methods that create and configure objects that are managed by Spring, enhancing the flexibility of your configuration.

📌 Key Points:
- Methods within a @Configuration class that are annotated with @Bean return instances of beans.
- These beans are singleton by default, meaning there's only one instance per Spring container.

💻 Example:
Here's a simple implementation:

@Configuration
public class AppConfig {

@Bean
public MyService myService() {
return new MyService();
}
}


In this example, the myService method returns a bean of type MyService, allowing Spring to handle its lifecycle.

🚀 Using @Configuration helps keep your code clean and modular, making it easier to manage dependencies and configurations.

Let's continue to learn and grow together! 💡
