You will be able to create any feature that an application may require because this book covers everything from the fundamentals to advanced features.

First things first: get your development environment ready and build your very first Spring Boot App. Data access, security, configuration, and testing are some of the more advanced subjects you'll cover as you go along. This crash course will teach you how to create RESTful services, use Spring Data JPA to integrate different types of data, and work with properties and YAML files to oversee configurations. You practice to manage application properties, get into the application of annotations, and master the Spring MVC architecture. It will teach you to manage form submissions, validate user input, and construct dynamic web pages using Thymeleaf templates. The book also covers topics like integrating front-end frameworks, handling errors, and deploying applications to cloud platforms and Kubernetes.

Issues with configuring URL authorization, implementing JWT authentication, and integrating with OAuth2 and OpenID Connect are some of the critical problems that are being solved in this book. Methods for troubleshooting auto-configuration issues, managing environment variables in Docker, and making use of performance testing tools such as JMeter are all topics that will be covered. Additionally, the book delves into the topic of how to integrate with Active Directory and LDAP for centralized user management and authentication. By the time you finish this book, you will know everything there is to know about Spring Boot application development, security, and deployment, so you can confidently take on real-world projects.
