Grails Goodness Notebook

Experience the Grails platform through code snippets

About the Book

In 2009 I started to write about features in Grails I didn't want to forget at my blog Messages from mrhaki. The posts are relatively short and filled with code samples.

The Grails Goodness Notebook contains the blog posts about Grails. The posts are bundled and categorized into sections. Each section starts with the simpler features and ends with more advanced Grails features. The book is intended to browse through the subjects. You should be able to just open the book at a random page and learn more about Grails. Maybe pick it up once in a while and learn a bit more about known and lesser known features of Grails.

The book is updated on February 1st 2016 with the following new posts:

  • Run Grails Application As Docker Container
  • Enable Hot Reloading For Non-Development Environments
  • Change Locale With Request Parameter
  • Go To Related Classes In IntelliJ IDEA
  • Quickly Create GSP From Controller In IntelliJ IDEA
  • Using Spring Cloud Config Server
  • Changing Gradle Version
  • Getting More Information About A Profile
  • Using Features When Creating An Application

The book categorizes the posts in the following sections:

  • Configuration
  • The Command LIne
  • Grails Object Relational Mapping (GORM)
  • Validation
  • Controllers
  • Groovy Server Pages (GSP)
  • REST
  • The Service Layer
  • Grails and Spring
  • Internationalization (i18n)
  • IDE
  • Miscellaneous

About the Author

Hubert Klein Ikkink
Hubert A. Klein Ikkink (mrhaki)

Hello. I am a passionate Groovy, Grails and Java developer based in Tilburg, The Netherlands. My goal is to write software, like Pixar makes movies, BMW makes cars, Bang & Olufsen makes audio and TV systems and Apple makes computers and devices: clean, elegant, user-centered and high quality.

My name is Hubert A. Klein Ikkink. Not a very common name, right? To make things easier I just picked the first letters of my firstname and surname and came up with haki. So there you have it, now I am known as Mr. Haki or mrhaki for short.

In 2009 I started writing blog posts about Grails with the name Grails Goodness. These posts contain small snippets of code explaining core and exotic features of the Grails platform.
