java - 如何使用java提取字符串并存储到数据库

Question

ID |记录类型 |记录数字 |来源SYSTEMID |目标系统 ID |

我在提取此数据并将其存储在数组列表中并插入数据库时​​遇到问题。你能帮我吗？..

这是我的代码:-

public void massageData(String tmp) {
    String Id = "";
    String RecordType = "";
    String RecordNumber = "";
    String sourceSystemId = "";
    String targetSystemId = "";
    String TelNo = "";

    String[] recArray = tmp.split("\\|");

    RecordType = recArray[1].trim();
    RecordNumber = recArray[2].trim();
    sourceSystemId = recArray[3].trim();
    targetSystemId = recArray[4].trim();
    TelNo = recArray[5].trim();

    Connection conn = null;
    ResultSet rs = null;
    PreparedStatement stmt = null;

    String actualMSISDN = parseMSISDN(TelNo);

    String iCtr = getiCtr(actualMSISDN);
    Id = recArray[0].trim();
    String stateCode = lookupStateCode(State);
    try {
        conn = ds.getConnection();
        // insert post process data to data_999 table
        String sQuery = "insert into DATA_999 (ID,RecordType,RecordNumber,SourceSystemApplicationId,TargetApplicationId,TelNo) values(?,?,?,?,?,?)";

        stmt = conn.prepareStatement(sQuery);
        int dbStat = stmt.executeUpdate();
        int isExist = chkMsisdn(actualMSISDN);
        if(isExist > 0) {
            // retrieve record from database
            icData oldData = getRecord(actualMSISDN);

            icData newData = new icData();
            stmt.setString(1, Id);
            stmt.setString(2, RecordType);
            stmt.setString(3, RecordNumber);
            stmt.setString(4, sourceSystemId);
            stmt.setString(5, targetSystemId);
            stmt.setString(6, TelNo);
        }
        conn.close();
    } catch(SQLException s) {
        logger.error(s.getMessage());
    } finally {
        try {
            if(stmt != null) stmt.close();
        } catch(SQLException e) {
        }
        try {
            if(conn != null) conn.close();
        } catch(SQLException e) {
        }
    }
}

有人发现这段代码中有任何错误吗？..请帮助我!!..我花了两周时间找出问题所在..arrgghhh..>_<.. 非常感谢您的关注、帮助和支持!..谢谢..:)

您似乎在设置参数 (stmt.setString()) 之前执行语句 (stmt.executeUpdate())。
