Video description

Spring Boot is a powerful framework that simplifies the development of REST services. It enables developers to effortlessly create production-ready Spring-based applications that can be run immediately.

Throughout the course, you will learn how to build web applications and REST APIs with Spring Boot, using auto-configuration, Spring Initializr, and starter projects. You will also learn how to connect to a database using JPA/Hibernate, write great unit and integration tests using Spring Boot Starter Test, and make the best use of Spring Boot Actuator and Spring Boot Developer Tools.

Additionally, you will learn how to externalize application configuration using Spring Boot profiles and dynamic configuration and understand the embedded servlet container options provided by Spring Boot. You will also gain a good understanding of the basics of developing a web application, including POST, GET, HTTP, and MVC patterns, as well as how to style your web page using the Bootstrap framework.

By the end of the course, you will have developed a basic Todo management Java application with login and logout functionalities, as well as a basic REST service to manage a survey questionnaire. You will also have gained a solid understanding of the features of Spring Boot and be well-equipped to start developing your own Spring Boot applications.
