Spring Developer Boot Camp | Mastering Spring 5.x

Course Objectives

This course provides a solid understanding of what Spring brings to the table and how to use Spring in the context of other technologies and frameworks.  Students are taken on an in-depth tour of the basic Spring framework, initially examining concepts such as Inversion of Control and Dependency Injection, and then working with the container and basic components.  Students are introduced to Spring Boot and use Spring Boot throughout the remainder of the course.   The latter part of the class looks at implementing REST with Spring and takes a deep dive into Spring Boot to prepare students for more extended Spring Boot usage following class.

Working in an engaging hands-on programming environment, students will learn to:

• Explain the issues associated with complex frameworks such as JEE and how Spring addresses those issues
• Write applications that take advantage of the Spring container and the declarative nature of assembling simple components into applications.
• Understand how to configure the framework Spring Boot and various options within Spring Boot for detailed configuration.
• Understand and work on integrating Sprint Data into a Spring application.
• Develop REST applications using Spring 5
• Work with Spring Boot to facilitate Spring setup and configuration

Need different skills or topics?  If your team requires different topics or tools, additional skills or custom approach, this course may be further adjusted to accommodate.  We offer additional Spring, programming, Microservices / Services, REST, TDD / testing, design, application security and other related topics that may be blended with this course for a track that best suits your needs. Our team will collaborate with you to understand your needs and will target the course to focus on your specific learning objectives and goals.

Course Prerequisites

This introduction to Spring development course requires that incoming students possess intermediate-level Java programming skills and practical hands-on Java experience. This class is geared for experienced Java 8 (or higher version) developers who are new to Spring, who wish to understand how and when to use Spring in Java and JEE applications.
