Mastering Spring Cloud

By: Piotr Mińkowski

Overview of this book

Developing, deploying, and operating cloud applications should be as easy as local applications. This should be the governing principle behind any cloud platform, library, or tool. Spring Cloud–an open-source library–makes it easy to develop JVM applications for the cloud. In this book, you will be introduced to Spring Cloud and will master its features from the application developer's point of view. This book begins by introducing you to microservices for Spring and the available feature set in Spring Cloud. You will learn to configure the Spring Cloud server and run the Eureka server to enable service registration and discovery. Then you will learn about techniques related to load balancing and circuit breaking and utilize all features of the Feign client. The book now delves into advanced topics where you will learn to implement distributed tracing solutions for Spring Cloud and build message-driven microservice architectures. Before running an application on Docker container s, you will master testing and securing techniques with Spring Cloud.

Using RestTemplate together with service discovery

In fact, an integration with service discovery is the default behavior of the Ribbon client. As you probably remember, we disabled Eureka for the client-side balancer by setting the ribbon.eureka.enabled property to false. The existence of service discovery simplifies a configuration of Spring Cloud components during inter-service communication, examples in this section.

Building example application

The system architecture is the same as for the previous example. To view the source code for the current exercise, you have to switch to the ribbon_with_discovery branch ( here-spring-cloud-comm/tree/ribbon_with_discovery). The first thing you will see there is a new module, discovery-service. We have discussed in detail almost all aspects related to Eureka inChapter 4,Service Discovery, so you should not have any problems with launching it. We run a singlestandaloneEureka server with really basic settings. It is...
