equals() and hashcode() in hbm2hbm

kkus · **Joined:** Wed Mar 15, 2006 1:48 pm **Posts:** 91

I searched this forum and found I can specify meta data in hbm to generate equals/hashcode() in POJO(a hbm2java task).

My question is how I can generate this meta data in hbm file from db(a hbm2hbm task). What should I put in reveng.xml file for this purpose? I am using 3.2 beta 7 with Oracle 9i and mySQl 5.0.

not currently possible via reveng.xml

change the hbm.ftl templates to do what you want.

I'm also interested in these feature because I know these from hibernate2 and middlegen I used 1 year ago for reverse engeneering. So please descripe it in Jira.

btw. what middlegen did years back with respect to equal/hashcode might not be the best thing....you realize that, right ? :)

I can imagine this. But I think it would be very convenience feature, if i could directly generated the correct hbm.xml-Files with any meta-tags i need/want. So why it isn't possible to extend the hibernate.reveng.xml-file with tags like "<use-in-equals>" or "<use-in-hash>"?

reguards,

Max,

Do you know if I can specify cascade="some value" in reveng.xml so it will be shown in hbm file? If not in reveng.xml where should I put? thanks!

Anyone know if this functionality has yet been added?

no and it probably won't be since it can all be specified externally in your cfg.xml
