Java Frameworks
 In Java technology there are frameworks that helps the programmers to build distributed applications easily.
 Example:
» Hibernate  Object Relationship Mapping Framework
» Struts  Web UI Framework
» Enterprise Java Beans  Oracle’s specification for server side components for persistence & messaging
» Log4J  Apache’s Framework for logging

Java Frameworks
 Problem:
» Applications that use the varied frameworks and services face scalability issues
» A lot of plumbing code needs to be written
 Need:
» Applications that use a number of frameworks and services have to remain maintainable
» Code should be loosely coupled with the frameworks so that testing and reusability becomes easy

Spring time...
 Open source (http://projects.spring.io/spring-framework/)
 Rod Johnson started SpringSource company and developed
Spring framework for Apache 2.0 in June 2003.

Spring Framework
 Spring Framework provides a light-weight solution to develop maintainable and reusable enterprise applications
 It provides simple and rich facilities to integrate various frameworks, technologies and services in the
application

Dependency Injection
 Central to the Spring Framework is Inversion of Control (IoC)
 Provides consistent means of configuring and managing
business objects
 Objects created by the container are also called managed
objects or beans
 The container can be configured by XML or Java Annotations

Model-View-Controller (MVC) Architecture

Model-View-Controller (MVC) Architecture
 Model-View-Controller architecture is used for interactive web-applications. This model minimizes the coupling between
business logic and data presentation to web user. This model divides the web based application into three layers:
» Model: Model domain contains the business logics and functions that manipulate the business data. It provides
updated information to view domain and also gives response to a query. And the controller can access the
functionality which is encapsulated in the model
» View: View is responsible for presentation aspect of application according to the model data and also responsible
to forward query response to the controller
» Controller: Controller accepts and intercepts user requests and controls the business objects to fulfil these
requests. An application has one controller for related functionality. Controller can also be depends on the type of
clients

Aspect Oriented Programming Support
 AOP address cross cutting concerns
 A typical use cases of AOP is generating logs

Big Data Extensions
 Spring XD (Xtreme Data) (http://projects.spring.io/spring-xd/) is a unified platform for
» Data ingestion,
» Real time analytics,
» Batch processing, and
» Data export.

Big Data Extensions
 Spring Data projects (http://projects.spring.io/spring-data/) provides consistent approach to access big data stores.
Commons JPA MongoDB Redis
Solr KeyValue Hadoop
Cassandra Elasticsearch Neo4j
Main Modules
Community Modules
REST
