Migration to Annotations from XDoclet

greg_barton · **Posted:** Fri Mar 04, 2005 1:07 pm

Is there going to be a migration tool for converting XDoclet tags to annotations? Also, if I start developing using XDoclet tags now (I can't start using annotations for various reasons) are there any problems one could easily anticipate in the conversion?

We do not plan to do so.

Would such a tool be useful to the community?

well - at some point the new toolset would be able to this based on the hbm.xml the xdoclet dumps out.....anyone interested in that should come around and help us with completing the various exporters we have.

What about a tool to compare the Configuration generated from annotations to the one created from *.hbm.xml?
This would allow to check that nothing has been altered/lost by using anotations in place of config files

what would such a tool do/look like ?

Very basically it could be overriding equals on Configuration. This would allow something like:

Code:

final Configuration oldConf = new Configuration().configure("hibernateOld.cfg.xml");

final AnnotationConfiguration newConf = (AnnotationConfiguration) new AnnotationConfiguration().configure();

assertEquals(oldConf, newConf);

This would be really basic and would not give any helpfull information when old and new configurations differs. Ideally a diff method taking 2 Configuration as parameters should say where the diferences are. A way to achieve that and give good human readable information could be to generate *.hbm.xml from the configuration. Users could then use their prefered diff tool.

You can generate a hbm.xml from a Configuration today - that is how the tools works. They dump the Configuration to various representations.

The tool that creates a hbm.xml is <hbm2hbmxml> and the Configuration can be provided via a <jdbcconfiguration>, <annotaitonconfiguraiton> or an "ordinary" <configuration>.

It is not 100% complete, so if you find something missing then please report it or even better provide a patch for it.

That's great! I was looking for something in the Annotation area and missed this one. Thanks.
