Hibernate中配置级联删除

首先，要在建表SQL中加入对级联删除的支持

CREATE TABLE `voteitem` (  `id` varchar(50) NOT NULL default '',  `title` varchar(50) default NULL,  `votenum` varchar(50) default NULL,  `vote_id` varchar(50) NOT NULL,  PRIMARY KEY  (`id`),  KEY `vote_id` (`vote_id`),  CONSTRAINT `voteitem_ibfk_1` FOREIGN KEY (`vote_id`) REFERENCES `vote` (`id`) ON DELETE CASCADE) ENGINE=InnoDB DEFAULT CHARSET=gb2312 ROW_FORMAT=COMPRESSED;

其次，在hibernate mapping文件中设置cascade

< set  name ="voteitems"  cascade ="delete"  order-by ="title asc"  inverse ="true" >          < key  column ="vote_id" ></ key >          < one-to-many  class ="Voteitems" />       </ set >
