前台获取到的是List<Record>

可以直接写sql; Db自带的封装好的；

public void listData() {
   Object[] queryParams = getQueryParams();
   String[] properties = (String[]) queryParams[0];
   String[] symbols = (String[]) queryParams[1];
   Object[] values = (Object[]) queryParams[2];

   String orderBy = getOrderBy();
   if(StringUtil.isEmpty(orderBy)) {
      orderBy = "id desc";
   }

   //List<Record> list = DBTool.findByMultPropertiesDbSource(TspaceConst.dbsource2, "equipment_unseal", properties, symbols, values, orderBy, getPager());
   List<Record> list = Db.find("SELECT\n" +
         "  a.equipment_name,\n" +
         "  b.ename,\n" +
         "  a.enclosure\n" +
         "FROM\n" +
         "  pub_db2.equipment_unseal a,\n" +
         "  pub_db1.she_bei_info b\n" +
         "WHERE CONVERT(a.equipment_name USING utf8) =CONVERT( b.ename USING utf8)");
   System.out.println("查询后的结果"+list);
   //SELECT [id], [name] FROM [表1] UNION ALL SELECT [id2], [name2] FROM [表2]
   renderDatagrid(
         list,
         DBTool.countByMultPropertiesDbSource(TspaceConst.dbsource2, "equipment_unseal", properties, symbols, values)
   );
}
