## 14.6 Property Override Configuration

Grails supports setting of bean properties via configuration. This is often useful when used in combination with externalized configuration.

Essentially you define a `beans` block with the names of beans and their values:

    beans {
        bookService {
            webServiceURL = "http://www.amazon.com"
        }
    }

The general format is:

    [bean name].[property name] = [value]

The same configuration in a Java properties file would be:

    beans.bookService.webServiceURL=http://www.amazon.com
