Master Spring Boot 3 and Spring Framework 6 to create scalable Java applications. Learn database integration, web development, monitoring, and deployment with modern best practices.Key FeaturesComprehensive coverage of Spring Boot 3 and Spring Framework 6 core concepts and modulesDetailed guidance on relational and NoSQL database integration for versatile data managementFocus on practical deployment, monitoring, and logging techniques for production-ready applicationsBook DescriptionThis 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.What you will learnBuild Spring Boot projects using dependency injection effectivelyConfigure relational and NoSQL databases for scalable applicationsDevelop RESTful APIs using Spring Web MVC and security best practicesImplement Jakarta Persistence and Spring Data JPA for data managementMonitor and log applications using Spring Boot Actuator and MicrometerDeploy Spring Boot applications with containers and cloud-ready setupsWho this book is forIdeal for Java developers aiming to deepen their Spring Boot and Spring Framework knowledge.
