Find classes that use certain annotation - Java, Spring

Code to read classes that use a certain annotation:

import org.springframework.beans.factory.config.BeanDefinition;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.ClassPathScanningCandidateComponentProvider;
import org.springframework.core.type.filter.AnnotationTypeFilter;
ClassPathScanningCandidateComponentProvider classPathScanningCandidateComponentProvider = new ClassPathScanningCandidateComponentProvider(false);
classPathScanningCandidateComponentProvider.addIncludeFilter(new AnnotationTypeFilter(CustomAnnotation.class));
Set < BeanDefinition > beanDefinitions = classPathScanningCandidateComponentProvider.findCandidateComponents("com.rake.demo.beans");
for (BeanDefinition beanDefinition: beanDefinitions) {
    System.out.println(beanDefinition.getBeanClassName());
}

Annotation:

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
@interface CustomAnnotation {
}

Usage:

@CustomAnnotation 
public class MyCustomClass {
}

Happy coding 👨‍💻
