加双重for循环后不分页了，正常查询就可以分页

public PageInfo findByParam(Map<String, Object> param)
  {
    PageHelper.startPage(Integer.parseInt((String)param.get("pageNum")), Integer.parseInt((String)param.get("pageSize")));
    //List list = this.orktapeMapper.findByParam(param);
    List<OrktapeName> li = orktapeMapper.getOrktapeName();
    List<Orktape> list = orktapeMapper.getOrk(param);
    for (OrktapeName a:li) {
      for (Orktape b:list) {
        String callnum = a.getCallnum().toString();
        if (callnum.equals(b.getLocalParty())){
          b.setLocalParty(a.getCallname());
        }
        if(callnum.equals(b.getRemoteParty())){
          b.setRemoteParty(a.getCallname());
        }
      }
    }
    return new PageInfo(list);
  }

PageHelper.startPage要放到mapper查询前一行
