Conventions used

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

Code in text: 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: “This can be done by first adding an application.properties file to our src/main/resources folder.”

A block of code is set as follows:

@Controller
public class HomeController {
  private final VideoService videoService;
  public HomeController(VideoService videoService) {
    this.videoService = videoService;
  }
  @GetMapping("/")
  public String index(Model model) {
    model.addAttribute("videos", videoService.getVideos());
    return "index";
  }
}

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

@Bean
SecurityFilterChain configureSecurity(HttpSecurity http) {
  http.authorizeHttpRequests()
    .requestMatchers("/login").permitAll()
    .requestMatchers("/", "/search").authenticated()
    .anyRequest().denyAll()
    .and()
    .formLogin()
    .and()
    .httpBasic();
  return http.build();
}

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

$ cd ch7
$ ./mvnw clean spring-boot:build-image

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “To do that, go to the Dependencies section.”
