Overview
During this three day course, participants explore the basic Spring framework, discovering concepts such as Inversion of Control, Dependency Injection and also work with containers and basic components. The course examines the improved Spring 5.x configuration management options such as XML, annotations, JavaConfig and Spring expression language. The course discusses areas of persistence and transactions, and the development of tests using JUnit 5 (Jupiter), accessing data using JDBC, Hibernate and the use of Spring Data. The course also explores Spring Boot briefly to help participants understand the configuration of Spring based applications in today’s microservices world.
