Spring is the most broadly used framework for the development of Java Enterprise Edition applications. Further, the core features of Spring can be used in developing any Java application.

Benefits

• Lightweight – There is a slight overhead of using the framework in development.
• Inversion of Control (IoC) – Spring container takes care of wiring dependencies of various objects instead of creating or looking for dependent objects.
• IoC container – manages Spring Bean life cycle and project-specific configurations
• Aspect-Oriented Programming (AOP) – Spring supports AOP to separate business logic from system services. It is a methodology that divides the program logic into pieces or parts or concerns.
• MVC framework – used to create web applications or RESTful web services, capable of returning XML/JSON responses
• Transaction management – reduces the amount of boilerplate code in JDBC operations, file uploading, etc., either by using Java annotations or by Spring Bean XML configuration file
• Exception Handling – Spring provides a convenient API for translating technology-specific exceptions into unchecked exceptions.
