Spring Boot 3 and Spring Framework 6 (eBook, ePUB)

The Comprehensive Guide to Modern Java Development

• Format: ePub

Produktbeschreibung

This book takes readers on a comprehensive journey through Spring Boot 3 and Spring Framework 6, starting with the essentials of dependency injection and Spring-managed containers. It then explores core modules and proxies to establish a strong foundation for Java application development. Early chapters guide readers through configuring Spring Boot projects and managing dependencies efficiently.
The middle sections focus heavily on database integration, including relational databases using Spring JDBC, Jakarta Persistence, and advanced Spring Data JPA techniques. Readers will also learn to work with NoSQL databases like MongoDB and Elasticsearch, enhancing their ability to handle various data storage solutions. The book covers the development of web applications using Spring MVC, RESTful API design, and securing web endpoints.
The final chapters emphasize application monitoring with Spring Boot Actuator, logging strategies, and practical deployment options including containerization. Alongside the core content, a dedicated migration chapter assists developers transitioning from Spring Boot 2 to version 3, ensuring they stay current with evolving best practices. This structured approach prepares readers to confidently build, monitor, and deploy modern, production-ready Java applications.
