Core Spring 4

Duration: 3 Days

Prerequisite:

Java SE programming experience and an understanding of object-oriented design principles. Fundamental knowledge of XML is helpful but not required. HOTT's course Java Programming or equivalent knowledge provides a solid foundation.

Course Description:

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.

Course Objectives:

•   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
