Building Microservices with Spring

Overview of this book

Getting Started with Spring Microservices begins with an overview of the Spring Framework 5.0, its design patterns, and its guidelines that enable you to implement responsive microservices at scale. You will learn how to use GoF patterns in application design. You will understand the dependency injection pattern, which is the main principle behind the decoupling process of the Spring Framework and makes it easier to manage your code. Then, you will learn how to use proxy patterns in aspect-oriented programming and remoting. Moving on, you will understand the JDBC template patterns and their use in abstracting database access. After understanding the basics, you will move on to more advanced topics, such as reactive streams and concurrency. Written to the latest specifications of Spring that focuses on Reactive Programming, the Learning Path teaches you how to build modern, internet-scale Java applications in no time. Next, you will understand how Spring Boot is used to deploying serverless autonomous services by removing the need to have a heavyweight application server. You’ll also explore ways to deploy your microservices to Docker and managing them with Mesos. By the end of this Learning Path, you will have the clarity and confidence for implementing microservices using Spring Framework. This Learning Path includes content from the following Packt products: • Spring 5 Microservices by Rajesh R V • Spring 5 Design Patterns by Dinesh Rajput

Developing a Spring Boot microservice

The easiest way to develop and demonstrate Spring Boot's capabilities is by using the Spring Boot CLI, a command-line tool.

The following are the steps to set up and run Spring Boot CLI:

  1. Install the Spring Boot command-line tool by downloading the file from the following location URL:
  1. Unzip the file into a directory of choice. Open a terminal window, and change the terminal prompt to the bin folder.


Ensure that the /bin folder is added to the system path so that Spring Boot can be run from any location. Otherwise, execute from the bin folder by using the command ./spring.

  1. Verify the installation with the following command. If successful, the Spring CLI version will be printed on the console as shown:
      $spring –-version
      Spring CLI v2.0.0.M1
  1. As the next step, a quick REST service will be developed in groovy, which is supported...
