Spring Application Framework Training (5 days)

The Spring Framework Course Overview

This course enables the experienced Java developer to use the Spring Application Framework to manage objects in a lightweight "IoC" (inversion-of-control) container; to create simple and complex Web applications; and to manage persistent objects using Spring's support for DAOs and transaction control. Spring is a far-reaching framework that aims to facilitate all sorts of Java development, including every level of multi-tier distributed systems. Here we focus on the Core and MVC modules, with a lighter (but by no means dismissive) touch on persistence through DAO and ORM modules.

The Core module gives the developer declarative control over object creation and assembly; this is useful for any tier of any Java application. So is Spring's validation framework, and so we study these things in a mix of standalone (J2SE) applications and Web applications deployed to the Tomcat server/container. Then students build Web applications that use the Spring MVC framework to rationalize their designs into coherent request/response cycles. They use Spring command objects to manage HTML forms and their data, and connect these to the validation framework. We connect our applications to persistent stores and study the DAO and ORM modules, to better understand JDBC and Hibernate persistence models and declarative transaction control.

A bridge module is also available that illustrates how Spring's persistence module compliments the Hibernate ORM framework; this brief presentation can easily be added to the end of the class and works especially well to cap off a week of training using this course and our Hibernate course.

The Spring Framework Course Goals

• Understand the scope, purpose, and architecture of Spring
• Use Spring's Inversion of Control to declare application components, rather than hard-coding their states and lifecycles
• Use Dependency Injection to further control object relationships from outside the Java code base
• Create validators for business objects, and associate them for application-level and unit-testing uses
• Build a Web application as a Spring DispatcherServlet and associated application context, with declared beans acting as controllers, command objects, and view resolvers
• Build and manage HTML forms with Spring command objects and custom tags
• Use Spring interceptors to implement horizontal features in the Web application
• Connect business objects to persistent stores using Spring's DAO and ORM modules

The Spring Framework Course Prerequisites

Experience in the following areas is required:

• Java programming
