Mastering Spring Boot 2.0

By: Dinesh Rajput

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.

Summary


We have covered creating a Spring Cloud Hystrix circuit-breaker and the circuit-breaker Pattern for fault tolerance in the distributed application. We created an application using Spring Netflix Hystrix to test both the circuit's open path and the circuit's closed path. We have implemented the client application to consume REST services by using Spring's RestTemplate and also used Spring Cloud's Netflix Feign.

We saw how to customize the default configuration of the Hystrix command and fallback. We also explored error propagation in the Hystrix command.

We created two REST consumer applications, one using RestTempate and another using the Feign client. And finally, we created a Hystrix Dashboard to monitor the metrics of your project. The Turbine dashboard helps to aggregate all the /hystrix.stream endpoints of all the microservices in the distributed system to a combine the /turbine.stream endpoints.

We learned why circuit-breaker implementation is necessary for building distributed...
