Spring Boot Training Overview
This Introduction to Spring 5, Spring Boot, and Spring REST training teaches experienced Java developers how to build modern Spring framework-based back-end applications. This class presumes that Spring is being used to construct a RESTful service back end and that a separate front-end will be constructed (most often using a client-side framework like React, Angular, or Vue).
Attendees learn the fundamentals of Core Spring and Spring Testing, then move on to Spring Boot (which simplifies creation and deployment of Spring applications) and Spring REST (for creating RESTful services). This class emphasizes both testability and security

Objectives
- 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 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
Prerequisites
All attendees must have at least one year of full-time Java and JSP development experience. Prior experience with servlets and JSP is recommended but not required.
