Introduction to Spring 4, Spring MVC and Spring REST

Course Code: hsts-c30


What is included in this course

Course Description

This course introduces the techniques for using the powerful capabilities of Spring 4 including the three main configuration styles: Java-based (@Configuration), annotation-based (@Component), and the traditional XML-based configuration that may still play an important role in existing and new projects. It also provides guidelines for when and how to use each one.

The course starts with in-depth coverage on using the powerful capabilities of Spring's Core module to reduce coupling and increase the flexibility, ease of maintenance, and testing of your applications. Coverage also includes integrating persistence layers (e.g. Hibernate/JPA) with Spring, using Spring's powerful Aspect Oriented Programming (AOP) to program cross-cutting concerns in a safe and maintainable way and using Spring's declarative transaction capabilities.

The course includes integrating Spring with Java EE Web applications and an introduction to Spring MVC. Spring MVC utilizes a Model-View-Controller pattern for building Web applications and the introduction covers the basics of Spring MVC and how it supports organizing your Web applications in a highly structured, loosely coupled manner. This includes an introduction to REST (Representational state transfer) and how to use Spring MVC to build RESTful resources and invoke them from Ajax-based front ends.

This course will enable you to build working Spring applications and give you an understanding of the important concepts and technology. Comprehensive hands-on labs provide reinforcement of the topics covered in the course and practical experience deploying solutions.

Students who do not require coverage of Spring MVC and RESTful Web Services may want to take the Introduction to the Spring 4 Framework class instead.

Students requiring an introduction to JEE Web Development, JDBC, JNDI, and JSP as well as Spring and Hibernate, may want to take the Web Application Development Using JEE, Frameworks, Web Services and AJAX class instead.

You will learn:


Course Prerequisites

Java SE 5 programming experience and an understanding of object-oriented design principles like Object Oriented Programming with UML Workshop. Fundamental knowledge of XML is helpful but not required. Our Java Programming or equivalent knowledge provides a solid foundation.
