hibernate插入不對(duì)
?為什么我用hibernate去save一條數(shù)據(jù)時(shí)，總是報(bào)ids?for?this?class?must?be?manually?assigned?before?calling?save():?cn.czq.entity.Product;?nested?exception?is?org.hibernate.id.IdentifierGenerationException:?ids?for?this?class?must?be?manually?assigned?before?calling?save():?cn.czq.entity.Product??但是只有id不自動(dòng)增加就沒問題
