In the previous two lessons, first we created our Spring Boot Microservice, Then we installed mariaDB and implemented a rudimentary CRUD with just GET methods. Now we are going to implement the full CRUD (Create, Read, Update, and Delete) using the following HTTP Requests (GET, POST, DELETE, and PUT) after that we are going to install Postman and use this to create Requests to test all our CRUD functionality. Read the JavaDocs We have provided JavaDoc Comments for all the Classes and Methods that we are now going to change to explain how they work.
