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: "We have used the @Controller annotation to indicate that the ProductController.java class is a controller class."

A block of code is set as follows:

@Controller
public class ProductController {
  @Autowired
  private ProductRepository respository;
  private List <Product>productList;
  public ProductController() {
    super();
  }

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

public class MailAdvice {
  public void advice (final ProceedingJoinPoint proceedingJoinPoint) {
    new Thread(new Runnable() {
    public void run() {

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

cd E:\MONGODB\mongo\bin
mongod -dbpath e:\mongodata\db

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: "The next step is to create a rest controller to send a mail; to do so, click on Submit."

Note

Warnings or important notes appear in a box like this.
