Summary
This course introduces the techniques for using the powerful capabilities of Spring 4 including the three main configuration styles
Description/Agenda
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. It also covers integration of Spring
with Java EE Web applications.
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 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.
Course Prerequisites
Java SE programming experience and an understanding of object-oriented design
principles. Fundamental knowledge of XML is helpful but not required.
What You Will Learn
- Understanding the core principles of Spring and of Dependency Injection
(DI) / Inversion of Control
- Using the Spring Core module and DI to configure and wire application
objects (beans) together
- Knowing the different types of metadata (XML, annotations/@Component,
and Java Configuration/@Configuration) and how
and when to use them
- Understanding and using the complete capabilities of the Core module,
such as lifecycle events, bean scopes and the Spring API
- Working with the ORM (Object-Relational Mapping) module to integrate
Spring with technologies such as Hibernate or JPA
- Understanding and using Spring's powerful AOP capabilities for
programming cross-cutting concerns across multiple points in an application
- Learning safe and maintainable techniques for programming with AOP
- Understanding and using Spring's transaction support, including the
easy-to-use Java annotation support, as well as the tx/aop XML configuration
elements
- Integrating Spring with Java EE Web applications
