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


In this chapter, we introduced and explained Feign, a declarative HTTP client developed by Netflix. We have learned how Feign simplifies HTTP API clients. We don't need to use a lot of boilerplate code to make the HTTP API clients application to access the microservices. You just simply use an annotated interface while the actual implementation will be created at the runtime.

The reader can learn to use Feign client and Hystrix support with the Feign client. This chapter has also implemented a custom encoder/decoder with exception handling for the Feign requests and responses. We have created some unit test cases to test the Feign client. The reader can also learn to use and customize the configurable options, such as logging and request compression.

In the next chapter, we will explore and implement event-driven systems.
