我这边有两张表,一张日程表(Calendar),一张打球人信息表(Play)

日程表的持久化类有这样的集合:

1 private Set<Play> plays = new HashSet<Play>(0);
2     public Set<Play> getPlays() {
3         return plays;
4     }
5     public void setPlays(Set<Play> plays) {
6         this.plays = plays;
7     }

打球人信息表里面有集合:

1  public Set<Calendar> getCalendars() {
2         return calendars;
3     }
4     public void setCalendars(Set<Calendar> calendars) {
5         this.calendars = calendars;
6     }

配置文件信息为:

Calendar.hbm.xml:
1 <set name="plays" inverse="true" table="cpguanxi" cascade="save-update">
2   <key column="cid"></key>
3     <many-to-many column="pid" class="bean.Play"></many-to-many>
4 </set>

Play.hbm.xml:

1 <set name="calendars" inverse="true" cascade="save-update" table="cpguanxi">
2             <key column="pid"></key>
3             <many-to-many column="cid" class="bean.Calendar"></many-to-many>
4         </set>

为什么级联保存的时候,我只能保存日程信息,打球人的信息保存不了呢?是不是配置哪边出问题了,请大神指点。

这是保存时的内容

 1      Calendar richeng = new Calendar();
 2         String date = "2015-04-05";
 3         int pNum = 2;
 4         String playTime = "7:00";
 5         int playId = 14;
 6         String fieldName = "Founders Club at Pawleys Island";
 7         richeng.setPlayTime(date);
 8         richeng.setPeopleNum(pNum);
 9         richeng.setOpenBall(playTime);
10         richeng.setPlayId(playId);
11         richeng.setName(fieldName);
12 
13         //添加此日程的打球人信息
14         Play play = new Play();
15         play.setName(name);
16         play.setOpid(playId);
17         play.setTel(tel);
18         richeng.getPlays().add(play);
19         play.getCalendars().add(richeng);
20         //调用services里面的方法保存日程信息
21         userService.saveRiCheng(richeng);
