The Abstract Factory design pattern is a creational software design pattern that provides a way to encapsulate a group of individual factories that have a common theme without specifying their concrete classes. The Abstract Factory pattern is also referred to as a Kit design pattern.
The Abstract Factory design pattern is useful in situations where a system must be independent from the way its objects are created, composed, and represented. The Abstract Factory design pattern is also useful in situations where a system must be configured with one of a number of families of applications.

There are several benefits to using the Abstract Factory design pattern:
The Abstract Factory design pattern should be used when:
The Abstract Factory design pattern can be implemented in Spring Boot using the JavaConfig and @Bean annotations.
JavaConfig:
@Configuration
public class AppConfig {
@Bean
public abstract Product1 product1();
@Bean
public abstract Product2 product2();
}
@Bean:
@Bean
public Product1 product1() {
return new Product1Impl();
}
@Bean
public Product2 product2() {
return new Product2Impl();
}
The Abstract Factory design pattern is used in the Java API, in the javax.xml.parsers package. The factory classes in this package, such as DocumentBuilderFactory and SAXParserFactory, are examples of the Abstract Factory design pattern.
The Abstract Factory design pattern is also used in the Hibernate framework, in the org.hibernate.cfg.Configuration class.
