Hibernate多对多级联(中间表)添加

SysJuese.java和SysBumen.java是多对多关系。主动权在SysBumen.java,数据库中表结果如下:
sys_bumen结构--
id bumenmingcheng miaoshu zhuangtai

sys_juese结构--
id juesemingcheng miaoshu zhuangtai

中间表sys_bumenjuese结构--
bumen_id juese_id

目前sys_bumen中有一条记录--

1 采购部。。。 0

现在想对sys_juese添加一条记录，同时在中间表sys_bumenjuese中也添加一条记录

代码如下:

=================================我也是华丽的分割线===================================

遇到的错误：

org.springframework.orm.hibernate3.HibernateSystemException: a different object with the same identifier value was already associated with the session:

在进行更新SysBumen设置Juese集合时，Juese集合每次需要new。使用Spring管理事务之后，如果更新对象中的Juese每次不新建，会出现session重复的问题。Hibernate不能同时更新两个拥有同一id的对象。
