Using Grails GORM standalone

问题:

I'm currently wondering how it is possible to use the Groovy ORM Layer from Grails standalone outside of the Grails Framework. There is a Documentation Entry for doing so, but the ZIP file only links to an empty page. I downloaded Grails 1.2-M3 but I couldn't find anything in the docs either.

Does anybody know what the current state is and how to accomplish this?

回答1:

AFAIK it is possible to use GORM standalone since Grails 1.1. This allows you to use GORM as your ORM without using the full Grails framework

However, I don't think it's possible to use GORM outside of Spring (which is the foundation on which Grails is built). To summarise:

• You can use GORM without using Grails
• You cannot use GORM without using Spring

A sample application demonstrating how to use GORM outside Grails is available here. If you want to browse the source code of this example in a browser (instead of checking it out from the SVN repository), start here.

As of Grails 2.3.6, GORM is officially supported as a standalone module. See the release notes for more details.
