Introduction To Spring Training

 

Introduction to Spring – 2 Days

Course Description

The Introduction to Spring training 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, and so this material also forms the basis for other Spring courses on persistence, web applications, and REST web services.

What You Will Learn

  • Understand the scope, purpose, and architecture of Spring.
  • Use Spring 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.
  • Configure systems of Spring beans using either Java or XML.

Prerequisites

  • Java programming is excellent preparation.
  • Basic knowledge of XML is recommended but not essential.
