Introduction to Spring 5, Spring Boot, and Spring REST

Introduction to Spring 5, Spring Boot, and Spring REST (SPR124)

Course Length: 5 days
Delivery Methods: Available as private class only
Course Overview

This Spring 5 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 JPA persistence layers with Spring and Spring Data, and using Spring’s declarative transaction capabilities.

The course includes a solid introduction to Spring REST, and coverage of building RESTful resources. It also covers many of the details of Spring Boot, including how to create Boot-based POMs (Maven) for simplified dependency management, customizing Boot behavior, and understanding/managing Boot’s auto-configuration.

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.

For private groups, we can customize the class to teach the “classic” approach to Spring, which involves writing all the configuration yourself rather than using Spring Boot to automate that process by selecting the most common configuration. Additionally, for development teams already experienced with Spring but is new to Spring Boot, we can provide a shorter custom course on Spring Boot.

Course Benefits
  • 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.
  • Learn the different types of metadata (XML, annotations/@Component, and Java Configuration/@Configuration), and how and when to use them.
  • Understand and use the complete capabilities of the Core module, such as lifecycle events, bean scopes, and the Spring API.
  • Use Spring Boot to simplify dependency management and configuration.
  • Understand and use Boot’s auto-configuration.
  • Customize Boot’s behavior with properties and in other ways.
  • Work with the ORM (Object-Relational Mapping) module to integrate Spring with technologies such as JPA.
  • Use Spring Data to automatically generate JPA-based repository classes.
  • Understand and use Spring’s transaction support, including the easy-to-use Java annotation support.
  • Understand REST, and use Spring REST to build RESTful services.
  • Use Ajax-based front ends with Spring REST.
  • Use RestTemplate to create Java REST clients.
