ResultSet：值无法插入HashMap

Question

我有一个函数，它将查询发送到我的数据库并将结果保存到结果集中。另一个函数应该采用结果集的值并将其放在hashmap中。如果我调试我的代码，获取db数据的函数返回结果集中的值，但如果我将该结果集作为参数提供给hashmap函数，则表示结果集为空。我从昨天起就坐在这个问题上，找不到任何答案。有人可以在我的代码中发现任何错误吗？

这是我的Hashmap函数和用于创建结果集的函数。

public HashMap<String, List<ResultSet>> toHashMap(ResultSet rset) throws SQLException, IOException {
        HashMap<String, List<ResultSet>> hmap = new HashMap<String, List<ResultSet>>();
        while (rset.next()) {
            String Processday = rset.getString("PROCESSDAY");
            if (hmap.containsKey(Processday)) {
                List<ResultSet> s = hmap.get(Processday);
                s.add(rset);
            } else {
                List<ResultSet> newList = new ArrayList();
                newList.add(rset);
                hmap.put(Processday, newList);
            }
            System.out.println(hmap.size());
            // convertToKML(distance, ax, ay, sx, sy, out);
        }
        return hmap;
    }

这是我的结果集函数。

public ResultSet getDBData(Connection conn, String[] args, RequiredMethods kml) throws SQLException{
        ResultSet rset;
        stmt = conn.createStatement();
        String sql_query;
        String[] userinput = kml.getUserInput(args);
        // String sql_query = "SELECT * from STOPPOINT_CORRECTED_BVAGG WHERE
        // trunc(PROCESSDAY) BETWEEN to_date('" + dateargs +"','ddmmyy') AND
        // to_date('" + toDate +"','ddmmyy') AND actualx is not null and
        // actualy is not null and distance is not null";


        if(userinput[0].isEmpty()){
            sql_query = "select distinct(trunc(PROCESSDAY)) PROCESSDAY,STOPPOINTID,ACTUALX,ACTUALY,SCHEDULEDX,SCHEDULEDY, DISTANCE from tabletest  WHERE trunc(PROCESSDAY) = to_date('" + kml.getDateAsString()
                + "','ddmmyy') AND actualx is not null and actualy is not null and distance is not null";
        }
        else if (userinput[1] == null) {
            sql_query = "select distinct(trunc(PROCESSDAY)) PROCESSDAY,STOPPOINTID,ACTUALX,ACTUALY,SCHEDULEDX,SCHEDULEDY, DISTANCE from tabletest  WHERE trunc(PROCESSDAY) = to_date('" + userinput[0]
                    + "','ddmmyy') AND actualx is not null and actualy is not null and distance is not null";
        }else{
            sql_query = "select distinct(trunc(PROCESSDAY)) PROCESSDAY,STOPPOINTID,ACTUALX,ACTUALY,SCHEDULEDX,SCHEDULEDY, DISTANCE from tabletest  WHERE trunc(PROCESSDAY) BETWEEN to_date('" + userinput[0]
                    + "','ddmmyy') AND to_date('" + userinput[1]
                    + "','ddmmyy') AND actualx is not null and actualy is not null and distance is not null";
        }
        System.out.println(sql_query);
        rset = stmt.executeQuery(sql_query);
        System.out.println("Query sent");



                    /*while(rset.next()){
                        System.out.println(rset.getString("ACTUALX"));  
                    }*/


        return rset;
    }
