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: "Let's add a Logger to the class; in our case, we can use UserController."

A block of code is set as follows:

@ResponseBody
  @RequestMapping("/test/aop/with/annotation")
  @TokenRequired
  public Map<String, Object> testAOPAnnotation(){
    Map<String, Object> map = new LinkedHashMap<>();
    map.put("result", "Aloha");   
    return map;
  }

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

2018-01-15 16:29:55.951 INFO 17812 --- [nio-8080-exec-1] com.packtpub.restapp.HomeController : {test} info
2018-01-15 16:29:55.951 WARN 17812 --- [nio-8080-exec-1] com.packtpub.restapp.HomeController : {test} warn 
2018-01-15 16:29:55.951 ERROR 17812 --- [nio-8080-exec-1] com.packtpub.restapp.HomeController : {test} error

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

mvn dependency:tree

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: "Now you can generate the project by clicking Generate Project."
