What is Framework?
- A framework is a platform for developing software applications.
- It provides a foundation on which software developers can build programs.
- In other words, the framework is a collection of classes and libraries.
What is Spring?
- Spring is an open-source application framework for the Java platform.
- It is a popular framework for building enterprise Java applications.
- Spring framework is used to wire different components together.
- Spring provides modular and flexible architecture which helps developers scalable and maintainable applications.
- Spring framework plays an important role in the development of large-scale and complex applications.
Explain the important features of the Spring framework
Spring IoC:
- Spring IoC container manages the life cycle of Java beans also known as objects.
Spring DI:
- Spring implements DI to inject dependencies into objects at runtime.
Aspect-Oriented Programming (AOP):
- AOP allows developers to modularize cross-cutting concerns, such as logging, security, and transaction management by separating them from the main business logic.
Model-View-Controller(MVC):
- Spring MVC is a powerful web module that allows the development of web applications based on MVC design patterns.
- It is a robust and flexible web development framework.
Data Access:
- Spring provides a simplified approach for data access supporting various databases like relational databases, NoSQL databases, and in-memory data storage.
- It is possible to simplify database operations by using the Spring Data JPA Project.
Testing:
- Spring supports unit testing and integration testing through the use of the Spring TestContext framework so that developers can easily write tests.
Security:
- Spring Security provides extensible support for authentication and authorization in Java Enterprise applications.
- It is the standard solution for securing Spring-based applications.
- It supports Servlet API integration.
Microservices:
- Microservices are a modern approach to software where application code is delivered in small, manageable pieces, independent of others.
- Microservices are easier to maintain as well as it improves productivity.
