Spring boot has an annotation, @SpringBootApplication, which allows the Spring Boot application to autoconfigure third-party libraries and detected features found on the classpath. [16] As an example, the class that has the @SpringBootApplication annotation can extend the SpringBootServerInitializer class if the application is packaged and ...
Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should favor polymorphic behavior and code reuse by their composition (by containing instances of other classes that implement the desired functionality) over inheritance from a base or parent class. [2]
The modified object is often a class, a prototype, or a type. Extension methods are features of some object-oriented programming languages. There is no syntactic difference between calling an extension method and calling a method declared in the type definition. [1] Not all languages implement extension methods in an equally safe manner, however.
If a trait requires the consuming class to provide certain methods, the trait cannot know if those methods are semantically equivalent to the trait's needs. For some dynamic languages, such as Perl, the required method can only be identified by a method name, not a full method signature, making it harder to guarantee that the required method is appropriate.
