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.

This course combines engaging instructor-led presentations and useful demonstrations with valuable hands-on labs and engaging group activities. Throughout the course you will learn how to:

• Explain the issues associated with complex frameworks such as JEE and how Spring addresses those issues
• Understand the relationships between Spring and JEE, AOP, IOC and ORM.
• Write applications that take advantage of the Spring container and the declarative nature of assembling simple components into applications.
• Understand how to configure the Spring Boot framework
• Understand and work on integrating persistence into a Spring application
• Work with Spring Boot to facilitate Spring setup and configuration
• Apply Aspect Oriented Programming (AOP) to Spring applications
• Use Spring Data JPA to implement the persistence layer of an application
• Develop REST applications using Spring 5
• Work with Spring Boot to facilitate Spring setup and configuration

If your team requires different topics, additional skills or a custom approach, our team will collaborate with you to adjust the course to focus on your specific learning objectives and goals.

This course is geared for experienced Java developers new to Spring.
