Modules of Spring Framework:-
Spring have the following seven modules. They are
1 The core container:
The core container provides the essential functionality of the Spring framework.
A primary component of the core container is the BeanFactory, an implementation
of the Factory pattern. The BeanFactory applies the Inversion of Control (IOC)
pattern to separate an application's configuration and dependency specification
from the actual application code.
2 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, e-mail, internalization, validation, and scheduling functionality.
3 Spring AOP:
The Spring AOP module integrates aspect-oriented programming functionality
directly into the Spring framework, through its configuration management
feature. As a result you can easily AOP-enable any object managed by the Spring
framework. The Spring AOP module provides transaction management services for
objects in any Spring-based application. With Spring AOP you can incorporate
declarative transaction management into your applications without relying on EJB
components.
4 Spring DAO:
The Spring JDBC DAO abstraction layer offers a meaningful exception hierarchy
for managing the exception handling and error messages thrown by different
database vendors. The exception hierarchy simplifies error handling and greatly
reduces the amount of exception code you need to write, such as opening and
closing connections. Spring DAO's JDBC-oriented exceptions comply to its generic
DAO exception hierarchy.
5 Spring ORM:
The Spring framework plugs into several ORM frameworks to provide its Object
Relational tool, including JDO, Hibernate, and iBatis SQL Maps. All of these
comply to Spring's generic transaction and DAO exception hierarchies.
6 Spring Web module:
The Web context module builds on top of the application context module,
providing contexts for Web-based applications. As a result, the Spring framework
supports integration with Jakarta Struts. The Web module also eases the tasks of
handling multi-part requests and binding request parameters to domain objects.
7Spring MVC framework:
The Model-View-Controller (MVC) framework is a full-featured MVC implementation
for building Web applications. The MVC framework is highly configurable via
strategy interfaces and accommodates numerous view technologies including JSP,
Velocity, Tiles, iText, and POI.
