自定义SQL中，我想在回调里面传入相应的参数，怎么传，是只能自己重写吗？
public List rptExplainExportExcel(String dzzId, String annualId, String explainId) {

    //先获得SQL
    RptTemplateExplain rptTemplateExplain = reportTemplateExplainService.getARptTemplateExplain(explainId);
    String querySql = rptTemplateExplain.getExportExcelSql();
    String columnNum = rptTemplateExplain.getExportExcelLength();

    Sql sql = Sqls.create(querySql);
    sql.params().set("dzzId", dzzId);

    //根据SQL先查出来该张报表的所有审核信息
    sql.setCallback(new SqlCallback() {

       public Object invoke(Connection conn, ResultSet rs, Sql sql) throws SQLException {
         List<ReportExplainFillEntity> reportExplainFillEntityList = new ArrayList<ReportExplainFillEntity>();
         while (rs.next()) {
          RptExplainExportExcel rptExplainExportExcel = new RptExplainExportExcel();
          for (int a = 1; a <= Integer.parseInt(columnNum); a++) {

          }
         }
         return reportExplainFillEntityList;
       }

    });
}

columnNum 是我想往回调里面传的参数
