This document provides an overview of the Spring framework, including its objectives, history, architecture, advantages, and the procedure for Spring programming. Spring is an open source Java framework that provides dependency injection and inversion of control for enterprise Java applications. It handles instantiation of objects and uses techniques like setter injection and constructor injection. The first version was written in 2003 and it has gone through several releases. The core Spring architecture includes modules for the container, data access/integration, and web layers.

- 2. Contents What is Spring ? Objective of Spring History of Spring Architecture of Spring Advantages of Spring Framework Procedure of Spring Programming
- 3. What is Spring ? The Spring framework is a Open Source Development Framework for Enterprise Java Applications. “The Spring framework provides central transaction control of various objects.”
- 4. Objective of Spring Spring controls instantiation of all the objects and passes a Spring reference to objects using various DI – Dependency Injection techniques like getter/setter injection and constructor injection (I.e. IoC - Inversion of Control).
- 5. History of Spring The 1st version was written by Rod Johnson The framework was 1st released under the Apache 2.0 license in June 2003, Spring 1.0 was released in March 2004, Spring 1.2.6 was released in March 2005, Spring 2.0 was released in October 2006, Spring 2.5 in November 2007, Spring 3.0 in December 2009, Spring 3.1 in December 2011, Spring 3.2.5 in November 2013. The current version is Spring Framework 4.0 was released in December 2013.
- 7. Core Container The Core Container consists the following Modules : Core Beans Context SPEL
- 8. Data Access/Integration The Data Access/Integration layer consists of the JDBC(Java Database Connectivity) ORM(Object Relational Mapping) OXM(Object XML Mapping) JMS (Java Message Service) Transaction
- 9. Web Layer The Web layer consists of the Web, Web-MVC, Web-Socket Web-Portlet
- 10. Advantages of Spring Framework Works on POJOs. Hence easier for dependency injection / injection of test data. Enhances modularity Provides more readable codes. Provides loose coupling between different modules. Effective in organizing the middle-tier applications. Flexible use of Dependency injection. Can be configured by XML based schema or annotation-based style. Supports declarative transaction, caching, validation and formatting.
- 11. Procedure of Spring Programming Create a Java Project Add required Libraries Create Source Files Create Bean Configuration File Running the Program
- 12. Create a Java Project File New Project and finally select Java Project .
- 13. Package Explorer
- 14. Add required Libraries • Build Path Configure Build Path • Add External JARs button available under Libraries tab to add the required JAR files
- 16. Create Bean Configuration File • create a Bean Configuration file which is an XML file and acts as cement that glues the beans i.e.. classes together. • This file needs to be created under the src directory as shown
