Exploring the Spring Framework: A Comprehensive Guide to Its Modules
The Spring Framework is a powerful, feature-rich framework for building Java applications. It provides comprehensive infrastructure support, allowing developers to focus on their application's business logic. The framework is modular, meaning you can pick and choose which parts to use, depending on your project's needs. In this blog post, we'll explore the various modules of the Spring Framework and provide a detailed table listing each module, its description, and its artifact ID.
Core Container
The Core Container consists of the core, beans, context, and expression language modules. These modules provide the fundamental parts of the framework, including dependency injection and bean management.
Data Access/Integration
This group includes JDBC, ORM, OXM, JMS, and Transaction modules. They provide support for data access and transaction management.
Web
The Web group includes the Web, Web-Servlet, Web-Struts, and Web-Portlet modules. These modules provide support for creating web applications.
AOP (Aspect Oriented Programming)
The AOP and Aspects modules provide support for aspect-oriented programming, which allows you to define cross-cutting concerns like logging and transaction management.
Instrumentation
The Instrumentation module provides support for class instrumentation and classloader implementations.
Test
The Test module supports the testing of Spring components with JUnit or TestNG.
Spring Framework Modules

| Context | Provides context information to the application, including internationalization and event propagation. | spring-context |
| Expression Language | Provides a powerful expression language for querying and manipulating an object graph at runtime. | spring-expression |
| AOP | Supports aspect-oriented programming, allowing the definition of cross-cutting concerns. | spring-aop |
| Aspects | Provides integration with AspectJ for advanced AOP features. | spring-aspects |
| Instrumentation | Supports class instrumentation and classloader implementations. | spring-instrument |
| JDBC | Provides support for JDBC data access, including connection and exception handling. | spring-jdbc |
| ORM | Provides integration with ORM frameworks like Hibernate and JPA. | spring-orm |
| OXM | Supports Object/XML mapping implementations. | spring-oxm |
| JMS | Provides support for Java Message Service (JMS) integration. | spring-jms |
| Transaction | Manages transaction management for Spring applications. | spring-tx |
| Web | Provides basic web-oriented integration features, such as multipart file upload functionality. | spring-web |
| Web-Servlet | Supports the development of web applications using Spring MVC. | spring-webmvc |
| Web-Struts | Provides integration with the Struts framework. | spring-webmvc-struts |
| Web-Portlet | Supports the development of portlet-based web applications. | spring-webmvc-portlet |
| Test | Supports the testing of Spring components with JUnit or TestNG. | spring-test |
The Spring Framework's modular architecture allows you to use only the parts you need, making it a versatile and powerful tool for Java development. Whether you're building a simple web application or a complex enterprise system, Spring has the components to support your project.
