Introduction to Spring 5, Spring MVC and Spring REST (Canada) On-Site Training

This on-site training class is also available as Public Schedule Seminar.

This course introduces these capabilities, as well as providing guidelines on when and how to use them. It includes coverage of 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.

Course Description/Agenda

Students 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
Using Spring Boot to simplify dependency management and configuration
Working with the ORM (Object-Relational Mapping) module to integrate Spring with technologies such as Hibernate or JPA
Using Spring Data to automatically generate JPA-based repository classes
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
Building Web applications with Spring MVC, including configuration using Java config and Servlet 3 capabilities
Understanding and using the core capabilities of Spring's Reactive programming support
Understanding REST and using Spring MVC to build RESTful services
Using Ajax-based front ends with Spring MVC / Spring REST

Course Description

Spring 5 provides an evolutionary advance of Spring's powerful capabilities. This course introduces these capabilities, as well as providing guidelines on when and how to use them. It includes coverage of 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.

The course starts with in-depth coverage of Spring's Core module to reduce coupling and increase the flexibility, ease of maintenance, and testing of your applications. It goes on to cover many of the most important capabilities of Spring, including easing configuration with Spring Boot, integrating Hibernate and JPA persistence layers with Spring and Spring Data, and using Spring's declarative transaction capabilities.

The course includes integration of Spring with Java EE Web applications, a solid introduction to Spring MVC, and coverage of building RESTful resources with Spring MVC. It also provides an overview of Springs reactive programming model for repositories and Web resources.

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 can be made available for all major development environments, including IBM RAD and IntelliJ.

Course Prerequisites

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.
