       }
       @Transactional
       public void saveApprove() {
       this.approve.setBaoxiao(getBaoxiao());
       this.approve.setDate(new Date());
       this.approve.setUser(user);
      
       em.persist(this.approve);
       em.flush();
       }
      
       public Baoxiao getBaoxiao() {
       return baoxiao;
       }
      
       public void setBaoxiao(Baoxiao baoxiao) {
       this.baoxiao = baoxiao;
       }
      
       public Approve getApprove() {
       return approve;
       }
