Course Overview

This Introduction to Spring 5 training class introduces Spring’s capabilities and provides 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.

Java developers who want to learn about RESTful services with Spring and dig deeper into Spring Boot should consider Webucator’s Introduction to Spring 5, Spring Boot, and Spring REST course.

Course Benefits
  • Understand the core principles of Spring, and of Dependency Injection (DI) / Inversion of Control.
  • Learn to use the Spring Core module and DI to configure and wire application objects (beans) together.
  • Understand 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.
  • Learn to use Spring Boot to simplify dependency management and configuration.
  • Learn to work with the ORM (Object-Relational Mapping) module to integrate Spring with technologies such as Hibernate or JPA.
  • Learn to 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, as well as the tx/aop XML configuration elements.
  • Learn to integrate Spring with Java EE Web applications.
