What annotations are you familiar with for defining configuration?

In Java, annotations from the Spring Framework and other libraries are often used to define configuration. The main ones include:

• @Configuration — indicates a class that contains bean definitions.
• @Bean — marks a method that creates and returns a bean.
• @ComponentScan — specifies packages to scan for components.
• @PropertySource — includes an external configuration file.
• @Value — injects a value from the configuration into a field.

Example:

@Configuration
@PropertySource("classpath:application.properties")
public class AppConfig {

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