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.

Building a server-side application


We have started by discussing HTTP, a resource-based API provided by the Spring Cloud Config Server, and the way of creating and storing properties there. But now let's move back to the basics. The same as a discovery server, a Config Server may be run as a Spring Boot application. To enable it on the server side, we should include spring-cloud-config-server in our dependencies in the pom.xml file:

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-config-server</artifactId>
</dependency>

In addition to this, we should enable the Config Server on the main application class. It would be a good idea to change the server port to 8888, because it is the default value of the spring.cloud.config.uri property on the client side. For example, it is auto configured on the client side. To switch the server to a different port, you should set the server.port property on 8888 or launch it with the...
