hibernate插入不對
?為什么我用hibernate去save一條數據時，總是報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不自動增加就沒問題

這要看你用的什么數據庫，如果是oracle你把generator 該為assigned, 如果是mysql你要設置為native，你可以試下
