hibernate多对多问题（急）
我在做一个系统管理的东西
需要添加角色和功能等信息
在添加角色时可以选择他所具有的功能所以需要使用多对多关系
现在的问题是
角色可以顺利添加进去，但是角色与功能的关系表中却没有计入任何信息
而角色持久化对象中的Set中也已经具有了功能对象
很郁闷
项目开发很急
请各位高手指点
以下是代码：
Role.hbm.xml
<hibernate-mapping>
<class name= "com.wtkj.ebiesf.persistent.dao.systemdao.Role " table= "T_YINGY_XT_JS " schema= "USZHXJC ">
<id name= "xh " type= "java.lang.Long ">
<column name= "XH " precision= "10 " scale= "0 " />
<generator class= "assigned " />
</id>
<property name= "jsdm " type= "java.lang.String ">
<column name= "JSDM " length= "20 " />
</property>
<property name= "jsmc " type= "java.lang.String ">
<column name= "JSMC " length= "100 " />
</property>
<property name= "jsms " type= "java.lang.String ">
<column name= "JSMS " length= "100 " />
</property>
<property name= "jsfl " type= "java.lang.String ">
<column name= "JSFL " length= "3 " />
</property>
<set name= "TYingyXtGndjses "
table= "T_YINGY_XT_GNDJS "
cascade= "save-update "
inverse= "true "
>
<key column= "XH_FKJS "> </key>
<many-to-many class= "com.wtkj.ebiesf.persistent.dao.systemdao.Function " column= "XH_FKGN "> </many-to-many>
</set>
</class>
</hibernate-mapping>
其中 XH_FKGN 是关系表中存放功能ID
XH_FKJS 是关系表中存放角色ID
TYingyXtGndjses 角色中的Set （因为是hibernate自动生成的所以不是很规范）
Function.hbm.xml
<hibernate-mapping>
<class name= "com.wtkj.ebiesf.persistent.dao.systemdao.Function " table= "T_YINGY_XT_GN " schema= "USZHXJC ">
<id name= "xh " type= "java.lang.Long ">
<column name= "XH " precision= "10 " scale= "0 " />
<generator class= "assigned " />
</id>
<property name= "gndm " type= "java.lang.String ">
<column name= "GNDM " length= "20 " />
</property>
<property name= "gnmc " type= "java.lang.String ">
<column name= "GNMC " length= "100 " />
</property>
<property name= "gnms " type= "java.lang.String ">
<column name= "GNMS " length= "200 " />
</property>
<property name= "sjgndm " type= "java.lang.String ">
<column name= "SJGNDM " length= "20 " />
</property>
<property name= "gnlj " type= "java.lang.String ">
<column name= "GNLJ " length= "200 " />
</property>
<property name= "gntp1 " type= "java.lang.String ">
<column name= "GNTP1 " length= "200 " />
</property>
<property name= "gntp2 " type= "java.lang.String ">
<column name= "GNTP2 " length= "200 " />
</property>
<property name= "mb " type= "java.lang.String ">
<column name= "MB " length= "10 " />
</property>
<set name= "TYingyXtGndjses "
table= "T_YINGY_XT_GNDJS "
cascade= "save-update "
inverse= "true "
>
<key column= "XH_FKGN "> </key>
<many-to-many class= "com.wtkj.ebiesf.persistent.dao.systemdao.Role " column= "XH_FKJS "> </many-to-many>
</set>
</class>
</hibernate-mapping>

保存时的代码贴出来看看啊，猜测也许是保存“角色对象”的时候“功能对象”没有保存
[解决办法]
关注,我也在看这个东西
