Spring Framework Training Overview

This Spring 5 and JPA2 training teaches students how to use Spring Boot for dependency management and to create JPA-based repositories using Spring Data. Students learn the three main configuration styles: Java-based (@Configuration), annotation-based (@Component), and the traditional XML-based configuration.

Spring Framework Training Objectives

All students will:

  • 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
  • Know 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 the benefits of JPA and the JPA Architecture
  • Create JPA based applications
  • Work with the ORM (Object-Relational Mapping) module to integrate Spring with JPA.
  • Understand and use Spring's transaction support, including the easy-to-use Java annotation support, as well as the tx/aop XML configuration elements
  • Understand and use JPA mapping to map persistent objects to the database
  • Work with JPA queries and JPQL
  • Understand and work with collections and associations (Value and entity types, unidirectional, bidirectional, 1-1, 1-N, N-N
  • Use JPA's versioning support
  • Map inheritance hierarchies using JPA
  • Integrate Spring/JPA with Java EE Web applications
  • Use Spring Data to automatically generate JPA-based repositories with auto-generated queries
