Introduction to Spring Training (2 days)

Inroduction to Spring Class 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. 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" module of the framework, developing facility in instantiating, configuring, and assembling Spring beans for various purposes.

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 not only the assembly of object graphs, but also how to apply validation logic to those objects and to report errors to the user or to another software component.

Inroduction to Spring Class Goals

• Understand the scope, purpose, and architecture of Spring
• Use Spring's bean factories and application contexts 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
• Use annotations to take advantage of Spring post-processors for automated bean instantiation and wiring
• Create validators for business objects, and associate them for application-level and unit-testing uses
