Java EE with Vaadin, JPA, Microservices, Spring and Maven
Vaadin Framework, Microservices (REST), Spring, Spring Security, Hibernate, Spring Boot, Maven and JPA
Description
When I started software engineering, I always wanted to code without any configurations, version control or build server configurations. Later, I realized that coding is just one part of software engineering: architectural designs, design patterns and the ability to write reusable and loosely coupled software components are much more important parts of programming.
In this course we are going to talk about the basics of professional software engineering such as how to separate the code into multiple modules or how to use a build framework to build the final application for us.
Before developing the final application from scratch - that wire all the included technologies together - we will consider these technologies on a one by one basis.
In the first section we are going to consider Maven, one of the most popular build frameworks out there. The second chapter is about Java Persistence API and database related problems. The third chapter will cover Spring as far as the XML based configuration is concerned, then we will talk about the new way: the so-called Spring Boot. Finally, we are going to implement an application in which we are going to use all the technologies we have discussed.
