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.

6. Architecture of Spring

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

15. Create Source 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
