如何循環結果集並將其保存在地圖列表中

Question

我正在嘗試循環結果集並將值存儲在Map中並將地圖保存到列表中，但是當我執行時，對於第一次循環，我正確地獲取了數據，但是對於第二次循環，我接收了兩倍的值，如果循環運行了n次，我得到了n次結果。

下面是代碼！

List<HashMap<String, String>> value = new ArrayList<HashMap<String, String>>();
PreparedStatement selectStmt;
selectStmt = conn.prepareStatement("select * from ETR_INT_partc_DOCM  where DOCM_TYP_CDE ='22'");
ResultSet result = selectStmt.executeQuery();
while (result.next()) {
    HashMap<String, String> resultValues = new HashMap<String, String>();
    resultValues.put("PARTC_ID", result.getString("PARTC_ID"));
    resultValues.put("FILE_NME", result.getString("FILE_NME"));
    resultValues.put("LOC_ID", result.getString("LOC_ID"));
    resultValues.put("CRTE_DTE", result.getString("CRTE_DTE"));
    resultValues.put("CRTE_BY", result.getString("CRTE_BY"));
    value.add(resultValues);
    System.out.println(value);
    resultValues.clear();
}
genarateXML(value, sheet)

嘗試這個：

ResultSet result = selectStmt.executeQuery();
HashMap<String, String> resultValues;
while (result.next()) {
    resultValues = new HashMap<String, String>();
    resultValues.put("PARTC_ID", result.getString("PARTC_ID"));
    resultValues.put("FILE_NME", result.getString("FILE_NME"));
    resultValues.put("LOC_ID", result.getString("LOC_ID"));
    resultValues.put("CRTE_DTE", result.getString("CRTE_DTE"));
    resultValues.put("CRTE_BY", result.getString("CRTE_BY"));
    value.add(resultValues);
    System.out.println(value);
}
