Overview of this book

Spring is one of the best frameworks on the market for developing web, enterprise, and cloud ready software. Spring Boot simplifies the building of complex software dramatically by reducing the amount of boilerplate code, and by providing production-ready features and a simple deployment model. This book will address the challenges related to power that come with Spring Boot's great configurability and flexibility. You will understand how Spring Boot configuration works under the hood, how to overwrite default configurations, and how to use advanced techniques to prepare Spring Boot applications to work in production. This book will also introduce readers to a relatively new topic in the Spring ecosystem – cloud native patterns, reactive programming, and applications. Get up to speed with microservices with Spring Boot and Spring Cloud. Each chapter aims to solve a specific problem or teach you a useful skillset. By the end of this book, you will be proficient in building and deploying your Spring Boot application.

Introducing Spring Cloud Streaming


Spring Cloud Stream is a framework to build message-driven microservice applications. It abstracts away the message producer and consumer code from message-broker-specific implementations. Spring Cloud Stream provides input and output channels to service communications to the outside world. Spring Cloud Stream is created on top of Spring Boot, it can create a standalone and production-grade applications.Spring Integration provides the message broker's connectivity to the Spring Cloud Stream. Message brokers, such as Kafka and RabbitMQ, can be added easily by just injecting a binding dependency to the code of your application.

Let's see the Maven dependency for Spring Cloud Stream:

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-stream-reactive</artifactId>
</dependency>

In the preceding Maven dependency, we have added the Spring Cloud Stream dependency reactive model. Let's see how to enable...
