How To Learn Spring Framework

Spring Tutorial

Spring framework is an open up source Java platform that provides comprehensive infrastructure support for developing robust Java applications very easily and very rapidly. Jump framework was initially written by Rod Johnson and was kickoff released under the Apache 2.0 license in June 2003. This tutorial has been written based on Spring Framework version 4.ane.6 released in Mar 2015.

Why to Learn Spring?

Spring is the most popular application development framework for enterprise Coffee. Millions of developers effectually the earth use Leap Framework to create high performing, easily testable, and reusable code.

Spring framework is an open up source Java platform. Information technology was initially written past Rod Johnson and was first released under the Apache 2.0 license in June 2003.

Spring is lightweight when it comes to size and transparency. The basic version of Bound framework is around 2MB.

The core features of the Spring Framework can be used in developing any Java application, just there are extensions for edifice web applications on top of the Java EE platform. Spring framework targets to make J2EE evolution easier to utilise and promotes adept programming practices by enabling a POJO-based programming model.

Applications of Spring

Post-obit is the list of few of the cracking benefits of using Spring Framework −

POJO Based - Jump enables developers to develop enterprise-class applications using POJOs. The benefit of using only POJOs is that you do not need an EJB container product such as an application server only you have the option of using merely a robust servlet container such as Tomcat or some commercial production.
Modular - Leap is organized in a modular fashion. Fifty-fifty though the number of packages and classes are substantial, you take to worry merely about the ones you demand and ignore the rest.
Integration with existing frameworks - Spring does not reinvent the bicycle, instead it truly makes use of some of the existing technologies like several ORM frameworks, logging frameworks, JEE, Quartz and JDK timers, and other view technologies.
Testablity - Testing an awarding written with Jump is simple because environs-dependent code is moved into this framework. Furthermore, by using JavaBeanstyle POJOs, information technology becomes easier to utilize dependency injection for injecting test data.
Web MVC - Spring's spider web framework is a well-designed web MVC framework, which provides a great culling to spider web frameworks such as Struts or other over-engineered or less popular web frameworks.
Central Exception Handling - Spring provides a convenient API to translate technology-specific exceptions (thrown by JDBC, Hide, or JDO, for example) into consistent, unchecked exceptions.
Lightweight - Lightweight IoC containers tend to exist lightweight, particularly when compared to EJB containers, for example. This is beneficial for developing and deploying applications on computers with limited memory and CPU resource.
Transaction direction - Jump provides a consistent transaction management interface that tin can scale down to a local transaction (using a unmarried database, for case) and calibration upward to global transactions (using JTA, for instance).

Audience

This tutorial is designed for Java programmers with a need to understand the Leap framework in detail along with its architecture and bodily usage. This tutorial volition bring you at an intermediate level of expertise, from where you can take yourself to higher levels of expertise.

Prerequisites

Earlier proceeding with this tutorial, you should accept a good agreement of Java programming language. A bones agreement of Eclipse IDE is also required because all the examples accept been compiled using Eclipse IDE.
