is there a better way to impl equals() and hashcode() ?

as in the pojo, I can't find the unique properties in some case, that is, they might all be the same except the database identifier. I know it's a bad way of using database identifier to impl equals() and hashcode(), is there a better way when I can't determine the "bussiness key"?

not really

make them use whatever properties you want. Business key is preferable.

If u r using InteliJ, it has the feature to do it for you. If u r using Eclipse, go to http://commonclipse.sourceforge.net/index.html to download plugin.

I never write my own equals and hashcode since I found this plugin.
