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.

Configuring Hystrix in your application


We will cover Spring Cloud Netflix Hystix with an example we discussed in the previous chapters. We will use the same example and implement the circuit-breaker pattern, which creates a strategy against cascading failure at lower levels of services in a distributed system. We will configure Hystrix in our application of customer and Account microservices, as we discussed in the previous chapters:

  • Account microservice: This microservice will give some basic functionality to the Account entity. We will call this Account service from customer service to understand circuit-breaker. It will run on port 6060 in localhost.
  • Customer microservice: This is also a REST-based microservice where we will implement the circuit-breaker using Hystrix. The Account microservice will be invoked from this Customer microservice and we will see the fallback path once the Account service is unavailable. It will run on port 6161 in localhost.

Hystrix is monitoring methods that...
