The document discusses the Spring framework, an open source Java framework that provides lightweight containers and supports dependency injection. Spring simplifies application development through abstraction layers and dynamically generating common application logic. It supports POJO programming and loose coupling, and can be used to build various types of applications including web applications.

1.  Framework, Java Frameworks
 Spring Framework
 Dependency Injection
 Spring Features
 Spring Modules
 Containers
 Application

2.  Framework is a special software that provides
abstraction layer on core technologies and
simplifies application development process
by generating the common logics of
application dynamically.
 Java Frameworks
- ORM F/W
- Web F/w
- Java-Jee F/w

3.  Spring is and open source, light weight,
loosely coupled, aspect oriented, dependency
injection based java - jee framework software
to develop all kinds of java, jee applications
by getting abstraction layer on java, jee core
technologies.

4.  If underlying container or framework s/w or
server s/w or runtime environment
dynamically assigns or injects values to our
resources of the application then it is called
as “Dependency Injection”.
 If the resource of the application is explicitly
spending time to search and gather
dependent values from other resources, then
its called „Dependency Lookup”.

5.  Light weight technology
 Supports POJO, POJI model programming
 Loosely coupled
 Support for server managed services, and
also provides built in services
 Aspect Oriented programming
 Can develop all kinds of apps, all kinds of
logics
 Provides abstraction layer over ORM, Web
Frameworks.

6.  Provides light weight built-in containers
 Provides abstraction layer over Junit testing
 Provides abstraction layer over different
distributed technologies like
RMI, EJB, WebServices (REST), Hessian &
Burlap to develop business components and
distributed apps
 Provides springs own distributed technology
“HttpInvoker”.

7.  Spring Core Module
 Spring DAO
 Spring ORM
 Spring AOP
 Spring Web
 Spring Web MVC
 Spring JEE/ Context

10.  Container is a S/w Application or a java class
that can take care of the whole life cycle of
given resource.
 Eg: servlet container, Spring Container
 2 built-in Spring Containers
- BeanFactory
- Application Context

11.  Spring Interface
 Spring Bean class
 Spring Configuration file
 Client Application
