most of my mysql 5 tables have autogenerated id. however, I am not able to run hbm2java (v3.1.0 b5) to make the @GeneratedValue annotation *just* for needed ids. I can either have no @GeneratedValue or to have it on all ids, and both is not correct. ok, i can fix this manually and with hard-coded column names in getTableIdentifierStrategyName() but this is not the way to go.

So I just wonder: is it possible for hibernatetool to 'figure out' which columns are autogenerated and to produce valid annotation just where it is needed?

thanx in advance!

hbm2java doesn't autodetect anything, it just dumps the hibernate meta model...maybe you are talking about the reverse engineering ?

here you can set it in reveng.xml per table.

we don't have autodetection of the id generator yet. patches welcome.
