Learn the Spring Boot 3 micro framework and build your first Java-based cloud-native applications and microservices. Spring Boot is the lightweight, nimbler cousin to the bigger Spring Framework, with plenty of "bells and whistles." This updated edition includes coverage of Spring Native, which will help you speed up your Spring Boot applications, as well as messaging with Spring Boot, Spring GraphQL, Spring Data JDBC and reactive relational database connectivity (R2DBC) with SQL.

This new edition also covers enhancements to actuator endpoints, MongoDB 4.0 support, layered JAR and WAR support, support to build OCI images using Cloud Native Build Packs, changes to the DataSource initialization mechanism, and how bean validation support has moved to a separate spring-boot-validation-starter module. This book will teach you how to work with relational and NoSQL databases for data accessibility using Spring Boot with Spring Data, how to persist data with the Java Persistence APIs (JPA), MyBatis, and much more. You'll learn how to enhance your native cloud or web applications with other APIs such as REST and how to build reactive web applications using Spring Boot with WebFlux.

Spring is the most popular Java-based framework for building enterprise applications. The Spring Framework provides a rich ecosystem of projects to address modern application needs, like security, simplified access to relational and NoSQL datastores, batch processing, integration with social networking sites, and large volumes of data streams processing. As Spring is a very flexible and customizable framework, there are usually multiple ways to configure an application. Although it is a good thing to have multiple options, it can be overwhelming for beginners. Spring Boot addresses this “Spring applications need complex configuration” problem by using its powerful autoconfiguration mechanism.

Spring Boot is an opinionated framework following the “convention over configuration” approach, which helps build Spring-based applications quickly and easily. The main goal of Spring Boot is to help you quickly create Spring-based applications without requiring you to write the same boilerplate configuration again and again.

In recent years, the microservices architecture has become the preferred architecture style for building complex enterprise applications. Spring Boot is a great choice for building microservices-based applications using various Spring Cloud modules. This book will help you understand what Spring Boot is, how Spring Boot helps you build Spring-based applications quickly and easily, and the inner workings of Spring Boot using easy-to-follow examples.

Finally, you'll learn how to test applications using JUnit 5, as well as how to secure and deploy your application or service to cloud providers like Heroku. After reading Beginning Spring Boot 3, you'll have the skills needed to start building your own Spring Boot cloud-native, Java-based applications and microservices with confidence, and to take the next steps in your career.
