Conditional Bean Loading with @ConditionalOnProperty

This snippet demonstrates how to conditionally load a Spring Bean based on a configuration property. If 'app.feature.modern-mode' is set to 'true' in application.properties, the bean is created; otherwise, it is ignored.

java
@Configuration
public class FeatureConfig {
    @Bean
    @ConditionalOnProperty(name = "app.feature.modern-mode", havingValue = "true")
    public ModernService modernService() {
        return new ModernService();
    }
}
