Fast Track to Spring 2.0

Summary

Fast Track to Spring 2.x

Spring is a lightweight Java framework for building enterprise applications. Its Core module allows you to manage the lifecycle of your objects, and the dependencies between them, via configuration metadata (usually XML) and Dependency Injection / Inversion of Control. Its advanced capabilities provide support for JDBC and persistence frameworks like Hibernate (DAO and ORM modules), Aspect-Oriented Programming (AOP module), integration with Java Web technologies (MVC module), security, transactions, and more.

This course is a completely new course based on the Spring 2.0 and 2.5 releases. It starts with the basics of Spring and in-depth coverage on using the powerful capabilities of the Core module to reduce coupling, increase flexibility and ease the maintenance and testing of your applications.

The course goes on to cover all the important capabilities of Spring 2.0 / 2.5, including using Spring to simplify the creation of a persistence layer with JDBC and/or persistence frameworks like Hibernate, and using Spring's Aspect Oriented Programming (AOP) to program cross-cutting concerns such as transactions and security.

The course includes a brief introduction to Spring's Web MVC - - a Web framework based on the powerful Model-View-Controller pattern. This module covers the basics of Spring MVC, and how it supports organizing your Web applications in a highly structured, loosely coupled manner.

The course also includes a brief introduction to Spring Security which was integrated into the Spring project when Spring 2.5 was released. This module includes an overview of the Spring Security architecture, and how to use it to secure both Web application requests and bean invocations

This course is hands on with labs to reinforce all the important concepts. It will enable you to build working Spring applications, and give you an understanding of the important concepts and technology in a very short time.

The standard platform does all labs with the Eclipse IDE, and the lab instructions include detailed directions for setting up and using it. The course is available for all major development environments, including IBM RAD and IntelliJ.

Course Objectives

On completion of this course, the student should be able to

Understand the core principles of Spring, and of Dependency Injection (DI)/Inversion of Control
Use the Spring Core module and DI to configure and wire application objects (beans) together
Understand and use the complete capabilities of the Core module, such as lifecycle events, bean scopes, and the Spring API
Work with the DAO and/or ORM modules to create a well structured persistence layer with JDBC or Hibernate
Understand and use Spring 2.0's powerful new AOP capabilities for programming cross-cutting concerns across multiple points in an application
Understand and use Spring's transaction support, including Spring 2.0's easy to use tx/aop XML configuration elements, and Java 5 annotations
Understand how Spring MVC works, and how to build well-structured Web applications with it
Understand the basics of Spring Security, and how to secure Web apps and Spring managed beans with it
