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: "It is also important to bear in mind that the @Electronic qualifier identifies the decorated object."

A block of code is set as follows:

public interface Engineering {
  List<String> getDisciplines ();
}
public class BasicEngineering implements Engineering {

  @Override
  public List<String> getDisciplines() {
    return Arrays.asList("d7", "d3");
  }
}
@Electronic
public class ElectronicEngineering extends BasicEngineering {
   ...  
}
@Mechanical
public class MechanicalEngineering extends BasicEngineering {
   ...
}

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

@Loggable
@Interceptor
public class LoggedInterceptor implements Serializable {
  
  @AroundInvoke
  public Object logMethod (InvocationContext invocationContext) throws 
  Exception{
    System.out.println("Entering method : "
        + invocationContext.getMethod().getName() + " " 
        + invocationContext.getMethod().getDeclaringClass()
        );
    return invocationContext.proceed();
  }
}

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

creating bean.
intercepting post construct of bean.
post construct of bean

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: "After the user logs in, when they access Application 1, Application 2, or Application 3, they will not need to log in again. "
