(Quick Reference) ### Service Usage A service contains business logic that can be reused across a Grails application.

    grails create-service org.bookstore.Book
or with your favourite IDE or text editor.
    package org.bookstore

    class BookService {
        Book[] getBooks() {
            Book.list() as Book[]
        }
    }
