Service Usage
A service contains business logic that can be reused across a Grails application. In Grails a service is a class with a name that ends in the convention "Service" and lives in the grails-app/services directory. A service can be created with the create-service command:
grails create-service org.bookstore.Book
or with your favourite IDE or text editor.
package org.bookstoreclass BookService { Book[] getBooks() { Book.list() as Book[] } }
Refer to the user guide topic on Services for more information.
