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.

Developer tools

Spring Boot offers some other useful tools for developers. The really cool thing for me is that the application is automatically restarted whenever files on the project classpath change. If you use Eclipse as your IDE, the only thing you have to do to enable it is to add the spring-boot-devtools dependency to the Maven pom.xml. Then, try to change something in one of your classes and save it. The application automatically restarts, and it takes much less than stopping and starting in the standard way. When I start our sample application, it takes about 9 seconds, and automatic restart takes only 3 seconds:


We can exclude some resources if there is no need to trigger a restart when they are changed. By default, any file available on the classpath that points to a folder will...
