Answer from AI
When working with the Spring Framework, the following design patterns are often used:
-
Dependency Injection — the core principle of Spring, allowing management of dependencies between objects through configuration rather than hard coding.
-
Singleton — most Spring beans are created as singletons by default to ensure a single instance of the component within the application context.
-
Factory Method — Spring uses factory methods to create beans, for example, through configuration or annotations.
-
Proxy — used for aspect-oriented programming (AOP), for example, for transactions or logging.
-
Template Method — used in classes like JdbcTemplate, RestTemplate, where the overall algorithm is defined, and implementation details can be overridden.
-
Observer — through Spring ApplicationEvent and listeners.
These patterns help create flexible, extensible, and easily maintainable applications in Spring.
