To get the most out of this book

This book can be read without a computer or laptop to hand; you need nothing more than the book itself. However, to follow the examples in the book, you need Java 8, which you can download from http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html, and you will also need your favorite IDE for the examples. I have used the Spring Tool Suite (STS). Download the latest version of STS from https://spring.io/tools/sts/all according to your OS. Java 8 and STS work on a variety of platforms, including Windows, macOS, and Linux.

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: "As you can see, the service name is account-service, and it will run on port 1111."

A block of code is set as follows:

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
</dependency>

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

@Service
public class AccountServiceImpl implements AccountService {
@Autowired
            @LoadBalanced
            RestTemplate restTemplate;

            @HystrixCommand(fallbackMethod = "defaultAccount")
            public Account findAccount(Integer accountId) {
                        return
restTemplate.getForObject("http://ACCOUNT-SERVICE/account/{accountId}", Account.class, accountId);
            }

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "As you can see in the preceding screenshot, this is done by right-clicking on Test Plan and then selecting Add | Threads (Users) | Thread Group."
