Inversion of Control (IoC) Container: The core of the Spring Framework is the IoC container, which manages the lifecycle of Java objects (beans) and their dependencies. It allows developers to declare and configure beans and their relationships in XML configuration files or through Java annotations.
Dependency Injection (DI): The core of the Spring Framework is the IoC container, which manages the lifecycle of Java objects (beans) and their dependencies. It allows developers to declare and configure beans and their relationships in XML configuration files or through Java annotations.
Aspect-Oriented Programming (AOP): Spring provides AOP support, allowing developers to define cross-cutting concerns (e.g., logging, security, transactions) separately from the application’s business logic. AOP enables modularization of concerns and reduces code duplication.
Spring MVC: Spring MVC is a framework for building web applications using the Model-View-Controller architectural pattern. It offers features like request mapping, view resolution, and form handling to create web applications.
Data Access/Integration: Spring supports various data access and integration technologies, including JDBC, JPA (Java Persistence API), Hibernate, JMS (Java Messaging Service), and others. It provides templates and utilities to simplify database access and interaction with other systems.
Spring Security: Spring Security is a powerful authentication and authorization framework that provides features for securing web applications and RESTful services. It supports various authentication mechanisms, such as LDAP, OAuth, and more.
Spring Boot: Spring Boot is a project within the Spring ecosystem that simplifies the process of building production-ready applications by providing conventions, auto-configuration, and a set of pre-built starters. It aims to minimize the need for boilerplate code and configuration.
Spring Data: Spring Data is a subproject that simplifies data access in Spring applications. It offers consistent data access APIs for various data stores, including relational databases, NoSQL databases, and more.
Spring Batch:Spring Batch is a framework for building batch processing applications. It provides features like job scheduling, parallel processing, and retry mechanisms for batch jobs.
Spring Cloud: Spring Cloud is a set of tools and libraries that facilitate the development of distributed, cloud-native applications. It includes components for service discovery, configuration management, and communication between microservices.
Testing: Spring Framework supports unit testing and integration testing through various testing utilities, making it easier to write testable and reliable code.
