Java Spring Framework is a Java platform which offers complete infrastructural support to develop applications in Java. Any application running Java can access the core features of the framework. The spring framework enables programmers to design applications from POJOs (Plain Old Java Objects). The Spring framework modules consist of Data access/Integration blocks which include OXM, JMS, Transactions; the Web block consists of Servlet, Portlet, and Struts. Most importantly, the core container consists of Beans, Core, Context and Expression Language blocks.
Prerequisites for learning Java Spring Framework
Why learn Java Spring Framework?
Java Spring framework has become quite popular in the past few years due to its core features. The core concepts of java spring framework programming include Inversion of Control (IoC) container, which means the objects do not create or look for dependent objects but give their own dependencies. Another core feature of the programming is that it removes the dependency from the code of the application so that it can be easy to manage and test the application. Furthermore, it uses aspect-oriented programming, which breaks the program logic into multiple parts, which are known as concerns, which results in a cohesive development.

Introduction to the Java Spring Framework Tutorial
This exhaustive tutorial covers everything you need to know in order to use the Java Spring Framework. The tutorial has 24 videos, which explain all the features of the framework.
Here is a summary:
Tutorial 1,2 – Explain the concept of Dependency Injection and how to set up the development environment for Spring framework.
Tutorial 3 to 7 - Explain the Spring Bean Factory, role of the Spring as a container and how to write code with the Spring Bean Factory, the additional features of the ApplicationContext Object which could be a replacement option to the BeanFactory, the use of constructors to set the member variable values for your Spring beans, called as Constructor Injection , some techniques to resolve conflicts in the case of overloaded constructors and the use of dependency injection to inject an object dependency to a Spring bean.
Turorial 8 – Explains the concepts related to bean naming and usage like ‘alias’ and ‘idref, and how to write inner beans.
Tutorial 9,10 – Explains initializing collections, configuration features provided by Spring to wire dependencies automatically ie: Bean Autowiring and different types of autowiring with sample code.
Tutorial 11 to 13 – Explain the beans scope, using ApplicationContextAware interface and the bean definition inheritance.
Tutorial 14 – Explains two different ways to run methods on initialization and destruction of beans.
Tutorial 15 to 17– Explain the BeanPostProcessor Class and the BeanFactoryPostProcesser class and coding to interfaces
Tutorial 18 to 21 – Explains Spring Annotations for container configurations. ‘Required’, ‘Áutowired’, JSR-250 annotations, Component and Stereotype Annotations.
Tutorial 22 to 24 – Explains MessageSource interface to retrieve messages out of property files, Event handling in Spring, and a brief introduction to Aspect Oriented Programming concepts.
Introduction to the Spring Data JPA Tutorial
This tutorial is a series of blog posts which describes how you can create JPA repositories without writing any boilerplate code (repetitive code that is included in many places).
It consists of the following blog posts with examples:
Introduction-Provides a quick introduction to Spring Data JPA
Getting the Required Dependencies- Describes how you can get the required dependencies.
Configuration- Helps you to configure the persistence layer of a Spring application that uses Spring Data JPA and Hibernate.
CRUD operations for an entity- Describes how you can create a Spring Data JPA repository that provides CRUD operations for an entity.
All about Query Methods – Creating database queries with method names/with @Query Annotation/with Named Queries/with JPA Criteria API/with Querydsl
Sorting/Pagination Query results
Auditing – Creating time fields and user authentication
Custom Methods – Adding custom methods to repositories
Final blog explains how to perform integration testing of your JPA repositories.
Introduction to the To-do List For Novice Web Developers tutorial
If you are a developer but new to development on the web, then this is the right tutorial for you. This tutorial helps you develop Java based web applications in 7 days, but the core concepts like version control, application container, build automation, MVC design, web services remain the same for almost all the enterprise applications, so either way this tutorial will be of great help.
Day 1 – You will be introduced to the basics of a web application – different components, use of servlets and JSP.
Day 2 – You will learn basics of git and working with github with an introduction to Java Programming
Day 3 – You will get introduced to Maven and TOMCAT
Day 4 - Web MVC: MVC in Java, MVC in JSP and Spring and Spring Web MVC
Day 5 - You will learn about Hibernate Framework and Hibernate-Spring integration and logging services: Apache Log4j 2
Day 6 - You will get introduced to RESTful Web Services and JAX-RS. JSON and its usage in Java (encoding and decoding) is also explained
