Configuration Annotation

Introduction

The Configuration annotation in Bring is used to indicate that a class is a source of bean definitions. Bean definitions declared within a configuration class are registered during the invocation of BeanFactoryPostProcessors. The dedicated factory post processor for configuration classes is ConfigurationClassPostProcessor.

Beans inside a configuration class are created by adding methods and annotating them with the @Bean annotation. Configuration beans must be of Singleton scope and are registered before the beans defined inside them.

The @Configuration annotation in Bring plays a crucial role in declaring bean definitions and configuring the application context. It allows developers to define and organize beans in a modular and maintainable way.

Usage Example

@Configuration
public class MyConfiguration {
    // Bean definitions using @Bean annotations

    @Bean
    public MyBean myBean() {
        return new MyBean();
    }

    @Bean
    public AnotherBean anotherBean() {
        return new AnotherBean();
    }
}

In this example, MyConfiguration is a configuration class annotated with @Configuration. It declares two beans (myBean and anotherBean) using methods annotated with @Bean. These beans will be registered with the Bring context during the application context initialization.
