Caused by: org.hibernate.NonUniqueObjectException - 断点

Caused by: org.hibernate.NonUniqueObjectException

在做项目中碰见这样的问题，如下：
Caused by: org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.pcis.cus.vo.CusClientVO#002255207];

原因： 有一个具有相同值的不同对象已经与和 session 相关联。

解决（程序的一部分）：
//CusClientVO cusVo = new CusClientVO();
        CusClientVO cusVo = null;
        IUserDetails user = CurrentUser.getUser();
        try {
            if ("Same".equals(cusFlag)) {//被保险人和投保人是同一人
                cusVo = (CusClientVO)this.getById(CusClientVO.class, applicant.getCAppCde());
                if(cusVo==null){ //表示新增客户。
                    cusVo = new CusClientVO();
                }
                this.saveCusApplicant(applicant, cusVo);
                if(!applicantflag ){
                    cusVo.setTCrtTm(new Date());
                    cusVo.setCCrtCde(user.getOpRelCde());
                }
            }
            cusVo.setTUpdTm(new Date());
            cusVo.setCUpdCde(user.getOpRelCde());
            //
            this.saveOrUpdate(cusVo);
        } catch (DaoException ex) {
            BusinessServiceException e = new BusinessServiceException(ex);
            e.setErrorMsg("保存客户信息失败");
        }
