This course comprises sessions dealing with Inversion of Control (IoC),Dependency Injection (DI),Container configuration,Aspect Oriented Programming (AOP),testing,transaction management,Spring Boot,Spring Data JPA,Spring Web MVC,REST APIs,Spring Security,and the Actuator.
Course overview:
It is delivered using Spring v6 and Spring Boot v3 (Java v17) though the vast majority of the content is applicable to earlier versions and the trainer will point out the differences. Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.
Course objectives:
Course Objectives This course aims to provide the delegate with the knowledge to be able to develop (or contribute to the development of) secure Spring web applications/REST APIs that read from and write to persistent storage.

COURSE PREREQUISITES:
Requirements Delegates attending this course should be competent Java developers who have a good understanding of OO principles and are able to build simple applications that exploit APIs including Collections,IO,and JDBC. Delegates would also benefit from having some previous experience with Servlet programming. This knowledge can be obtained by attendance on the pre-requisite Java Programming 1 / Java Developer course.
Target audience:
Who will the Course Benefit? The Core Spring course will benefit Java developers who are new to Spring and want to develop/contribute large and complex enterprise-level applications.
