Spring is a Java application framework that provides comprehensive infrastructure support for developing Java applications. It includes modules for core functions, data access, MVC web apps, and other aspects like AOP. The core provides dependency injection and IoC. The DAO module abstracts JDBC coding. The ORM module integrates ORMs. The MVC module provides a MVC structure for webapps. AOP allows separating cross-cutting concerns. Using Spring promotes loose coupling, separation of concerns, and testability. It also supports integration with popular technologies and allows flexible usage of individual modules.

3. What is a Framework?

4. How many times???????
Transaction Management
Logging Persistence
Security
Authentication
Authorization

5. I HAVE DONE THAT BEFORE!!!!!!

6. A framework is an application or
partial application…

7. Advantages of a Framework

9. Spring Framework is a Java platform that provides
comprehensive infrastructure support for developing
Java applications.

10. Spring Is
Non Intrusive
Modular
10

11. Spring Architecture

13. Core Package
 Most fundamental part of the framework.
 IoC and Dependency Injection features
 Factory pattern based Bean Factory.

14. DAO Package
The DAO package provides a JDBC-abstraction
layer that removes the need to do tedious JDBC
coding and parsing of database-vendor specific
error codes.

15. ORM Package
 The ORM package
provides integration
layers for popular object-
relational mapping
APIs, including
JPA, JDO, Hibernate, and
iBatis.
 Using the ORM package
you can use all those
O/R-mappers in
combination with all the
other features Spring

16. MVC Pattern

17. MVC Package
 Spring's MVC package provides a Model-View-
Controller (MVC) implementation for
webapplications.
 Spring's MVC framework is not just any old
implementation; it provides a clean
separation between domain model code and
web forms, and allows you to use all the other
features of the Spring Framework.

18. Aspect Oriented Programming

20. AOP Example

21. AOP Package
Spring's AOP package provides an AOP
Alliance-compliant aspect-oriented programming
implementation allowing you to define, for
example, method-interceptors and pointcuts to
cleanly decouple code implementing
functionality that should logically speaking be
separated.

22. A Typical Spring Application

23. Why Use
Spring Framework?

24. Why use Spring?
 Wiring of components through Dependency
Injection
– Promotes de-coupling among the parts that make
the application
 Design to interfaces
– Insulates a user of a functionality from
implementation details
 Test-Driven Development (TDD)
– POJO classes can be tested without being tied up
with the framework

25. Why use Spring?
 Declarative programming through AOP
– Easily configured aspects, esp. transaction support
 Popular technologies
– Abstractions insulate application from specifics, eliminate redundant code
– EJB for J2EE
- Hibernate, iBatis, JDBC (for data access)
- Velocity (for presentation)
- Struts and WebWork (For web)
 Not an all-or-nothing solution
– Extremely modular and flexible
 Well designed
– Easy to extend
– Many reusable classes
