when i delete SuffererVO, i thought hibernate might run "delete from EXM_INSPECT_RESULT where SUFFERER_ID=?"
but hibernate out print sql:
Hibernate: delete from EXM_SUFFERER_SUIT where SUFFERER_ID=?
Hibernate: delete from EXM_SUFFERER_UNIT where SUFFERER_ID=?
Hibernate: update EXM_INSPECT_RESULT set SUFFERER_ID=null where SUFFERER_ID=?
