Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "RestTemplate is a utility class that abstracts the lower-level details of the HTTP client."

A block of code is set as follows:

    @SpringBootApplication
    public class Application {
      public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
      }
    }

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

    @Component
    class Receiver {
      @RabbitListener(queues = "TestQ")
      public void processMessage(String content) {
        System.out.println(content);
      }
    }

Any command-line input or output is written as follows:

$java -jar target/bootrest-0.0.1-SNAPSHOT.jar

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "If the services are being build up fresh using the Spring Starter project, then select Config Client, Actuator, Web as well as Eureka Discovery client."
