Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The last available version of the HTTP API endpoint, http://localhost:8889/client-service-zone3.yml, returns data identical to the input file."

A block of code is set as follows:

<dependency>
  <groupId>org.springframework.cloud</groupId>

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

spring:
 rabbitmq:

  port: 5672

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