For input string: "PORT" 报错

xwy

String dbKey = "gusao";
  String sql = "select * from news where id="+32+"";
  
  List<Map<String, Object>> lists = (List<Map<String, Object>>) DynamicDBUtil. findList(dbKey, sql);
  System.out.println(lists.toString()+","+lists.size());

在controller 里写的 老是 报  For input string: "PORT"  这个错误
