hibernate的分页模糊查询功能

@Override  public List<T> findPage(int page, int length, Map<String, Object> pram) {     List<T> result = null;       try      {  　　　　　　　　　 //初始化hql，this.entityClazz.getSimpleName()是泛型的真实类名，在构造函数中获取       String hql = "from " + this.entityClazz.getSimpleName() + " where 1=1 and "; //注意空格       Session session = this.sesionFactory.openSession(); //获取连接       if(!pram.isEmpty())  //判断有无条件       {         Iterator<String> it = pram.keySet().iterator(); //迭代map         while(it.hasNext())         {            String key = it.next(); //获取条件map中的key，即条件字段            hql = hql + key + " like " + "'%" + pram.get(key) + "%'" + " and "; //将字段和模糊值拼接成hql         }       }       hql += " 2=2"; //在hql末尾加上 2=2,方便hql再次拼接       System.out.println(hql);       Query query = session.createQuery(hql);        query.setFirstResult((page - 1) * length); //设置分页页码         query.setMaxResults(length);  //设置每页数据长度       result = query.list(); //返回结果集     } catch (RuntimeException re)       {         throw re;       }       return result;    }
