What
is Spring Framework?
- Spring is a multi-tier open-source lightweight application framework.
- It addresses most infrastructure concerns of enterprise applications.
- It is mainly a technology dedicated to enable us to build applications using POJOs (Plain Old Java Objects). This includes a well designed and managing java objects.
What
are the key advantages of Spring Framework ?
Spring
framework is a complete enterprise application framework with
multiple benefits.The following few are the key benefits:
- Spring is a Lightweight container
- It address issues of the business tier
- Spring framework provides perfect support for write code that is easy to test.
- Spring framework provides a great support for integration with various technologies of java in creating enterprise application.
- It avoids implementing many design patterns such as Single Pattern and Factory by providing a built in solution for these patterns.
It
can eliminate the need to use a variety of custom properties file
formats., by handling Configurations in a consistent way throughout
the application.- It provides a simple set of Annotations of easy Configuration of the system from the web presentation to the data access layer.
- Not required special deployment steps
What
are the features of Spring ?
Following
are the few of the important features if spring framework:
Lightweight:
Spring
framework provides the enterprise level services simplifying creating
java enterprise applications. This is lightweight when it comes to
size and transparency. The processing overhead in using Spring
Framework services is also very negligible.
IOC
(Inversion of Control) Container:
This provides a loose coupling between the objects in the system,
simplifying wiring the system.
Aspect
Oriented(AOP):
Spring
supports Aspect Oriented Programming that enables convenient
development by separating application business logic from system
services.
Web
MVC Framework:
Spring framework includes a web MVC framework simplifying developing
web MVC applications in java, this is highly configurable via
strategy interfaces and supports integrating with multiple view
technologies like JSP. Velocity, Tiles, iText and POI.
Transaction
Management:
Spring framework provides a simple unified abstraction layer for
accessing the transaction services from different environments such as
JTA, Hibernate, JDBC, JPA. This also support declarative transaction
service similar to the Java EE, EJB.
JDBC Abstraction Framework:
The JDBC abstraction layer of the Spring simplifies implementing the
DAOs using jDBC by providing a built-in solution for problems like
Code duplication, Resource handling and Exception handling where it
can convert the SQLException into meaningful exception hierarchy
simplifying the error handling strategy.
Integration
with Hibernate, JDO and iBATIS:
Spring provides best way of integrating with data access technologies such as Hibernate, JPA, JDO and iBATIS.
Spring
Remoting:
Spring
includes a support for integrating with various Remoting technologies
such as RMI, Hessian, Burlap and JAX-RPC. In addition this includes
its own remoting service to suite with few architectures.
