我剛剛使用spring PropertyEditors從我的web表單中設置了id的綁定，並注意到M：M記錄正在被刪除並重新插入。起初我以爲這是因爲我使用CustomCollectionEditor而發生的，但UserEditor也是如此。hibernate @ManyToMany刪除並重新插入
我的域對象都具有使用主鍵的equals/hashcode方法，如果對象尚未保存，則ref。
Hibernate: update delivery_team set name=? where id=?
Hibernate: delete from delivery_team_manager where delivery_team_id=?
Hibernate: delete from delivery_team_resource where delivery_team_id=?
Hibernate: insert into delivery_team_manager (delivery_team_id, user_id) values (?, ?)
Hibernate: insert into delivery_team_manager (delivery_team_id, user_id) values (?, ?)
Hibernate: insert into delivery_team_manager (delivery_team_id, user_id) values (?, ?)
Hibernate: insert into delivery_team_manager (delivery_team_id, user_id) values (?, ?)
我試着添加一個管理器，使用單獨的回發和記錄不被刪除。所以這顯然不是休眠問題。
@RequestMapping(value = "add_manager/{teamid}/{uid}", method = RequestMethod.GET)
public String addManager(@PathVariable Long teamid, @PathVariable Long uid, Model model) {
DeliveryTeam team = deliveryTeamService.getById(teamid);
User user = userService.loadUserById(uid, false);
team.getManager().add(user);
deliveryTeamService.save(team);
return "redirect:/delivery_team/update/" + teamid;
}
任何方式我可以得到綁定工作與休眠的好？我喜歡將經理更改包含在表單提交中。
