What are the seven modules of the Spring framework? for this question, this article introduces the corresponding analysis and solutions in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Spring is an open source framework created to address the complexity of enterprise application development. One of the main advantages of the framework is its hierarchical architecture, which allows you to choose which component to use, while providing an integrated framework for J2EE application development.

Seven modules of the Spring framework

Each module (or component) that makes up the Spring framework can exist alone or can be implemented jointly with one or more other modules. The functions of each module are as follows:

◆ core container: the core container provides the basic functions of the Spring framework. The main component of the core container is BeanFactory, which is the implementation of the factory pattern. BeanFactory uses the inversion of Control (IOC) mode to separate the application's configuration and dependency specifications from the actual application code.

◆ Spring context: the Spring context is a configuration file that provides context information to the Spring framework. The Spring context includes enterprise services such as JNDI, EJB, email, internationalization, checksum and scheduling capabilities.

◆ Spring AOP: through the configuration management feature, the Spring AOP module integrates aspect-oriented programming capabilities directly into the Spring framework. Therefore, you can easily make any object managed by the Spring framework support AOP. The Spring AOP module provides transaction management services for objects in Spring-based applications. By using Spring AOP, you can integrate declarative transaction management into your application without relying on EJB components.

The ◆ Spring DAO:JDBC DAO abstraction layer provides a meaningful exception hierarchy that can be used to manage exception handling and error messages thrown by different database vendors. The exception hierarchy simplifies error handling and greatly reduces the amount of exception code that needs to be written (such as opening and closing connections). Spring DAO's JDBC-oriented exceptions follow the general DAO exception hierarchy.

The ◆ Spring ORM:Spring framework inserts several ORM frameworks, providing object-relational tools for ORM, including JDO, Hibernate, and iBatis SQL Map. All of this follows Spring's generic transaction and DAO exception hierarchy.

◆ Spring Web module: the Web context module is built on top of the application context module, providing context for Web-based applications. Therefore, the Spring framework supports integration with Jakarta Struts. The Web module also simplifies the work of handling multipart requests and binding request parameters to domain objects.

◆ Spring MVC framework: the MVC framework is a full-featured MVC implementation for building Web applications. Through the policy interface, the MVC framework becomes highly configurable, and MVC hosts a number of view technologies, including JSP, Velocity, Tiles, iText, and POI.

The functionality of the Spring framework can be used in any J2EE server, and most of the features also apply to unmanaged environments. The core point of Spring is to support reusable business and data access objects that are not bound to specific J2EE services. There is no doubt that such objects can be reused between different J2EE environments (Web or EJB), stand-alone applications, and test environments.
