@ComponentScanleverages the Java 8 repeating annotations feature, which means we can mark a class with it multiple times: @Configuration @ComponentScan(basePackages = "com.baeldung.annotations") @ComponentScan(basePackageClasses = VehicleFactoryConfig.class) ...
In this example, we will create a custom annotation using @Target with the value 'TYPE' which means this annotation is applicable to a class, interface, and enum. Open Compiler import java.lang.annotation.*; // declaring the annotations @Target({ElementType.TYPE}) @interface Author_details {...

Target Object: They are the object on which advices are applied. Spring AOP is implemented using runtime proxies so this object is always a proxied object. What is means is that a subclass is created at runtime where the target method is overridden and advice are included based...
RUNTIME: Means that the annotation is going to be retained by the Java Virtual Machine and can be used in runtime via reflection. We will see several examples of this annotation in this tutorial. @Target: This one restricts the elements that an annotation can be applied to. Only one type...
