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

Spring Architecture


AOP Aspects Instrumentation

Test

JDBC ORM

OXM JMS

Transactions

Web Servlet

Portlet Struts

Beans Core ContextExpression Language

Core Container

WEB (MVC/Remoting)Data Access/Integration

Spring Framework Runtime

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.
