我只想插入一列和第二列，其余的列我不需要

你解决了使用此代码…感谢支持你的家伙，包 com.om.whms.examples

import java.sql.Connection;
import java.sql.PreparedStatement;

public class BiometricLogs {
public static void readBiometricFile(String fileName){
    BufferedReader br = null;
    try{
        br = new BufferedReader( new FileReader(fileName));
        Connection connection = DBConnection.getConnection();
        String strLine = "";
        while((strLine = br.readLine()) != null){
            String dateStr = strLine.substring(10, 20);
            String timeStr = strLine.substring(21, 30).trim();
            String idStr = (strLine.substring(0, 9)).trim();
            //System.out.println(idStr + "$" + dateStr + "$" + timeStr);
             String sql ="insert into attendence (biometric_id, date,

嗯……看看您的SQL语句，您似乎希望利用文件中的三列数据（生物识别id、日期和时间），而不是您所说的两列。它是哪一个？我想像示例一样插入第一列bometric id='1'，date=“2017-05-01”，time='09:30:00'就像我已经使用了它所应用的代码…只要看看它我的输出1 2016-07-13,14:51:53 12551 1 0 2 1 2016-07-13 14:51:53 1 255 1 0..它没有插入到数据库更改变量私有静态字符串DB_DRIVER=“oracle.jdbc.driver.OracleDriver”私有静态最终字符串DB_CONNECTION=“jdbc:oracle:thin:@localhost:1521:MKYONG”私有静态最终字符串DB_USER=“USER”私有静态最终字符串DB_PASSWORD=“PASSWORD”更改数据类型preparedStatement.setString（1，split1[0]）；preparedStatement.setString（2，split1[1]）；preparedStatement.setString（3，split1[2]）；文件读取分割值输出生物识别1日期：2016-07-13日志时间14:51:53生物识别1日期：2016-07-13日志时间14:52:42生物识别1日期：2016-07-13日志时间14:52:51生物识别1日期：2016-07-13日志时间14:53:06生物识别1日期：2016-07-13日志时间14:53:10生物识别3日期：2016-07-16g_时间16:07:34生物特征识别码4日期：2016-07-16日志时间16:08:50生物特征识别码5日期：2016-07-16日志时间16:09:33生物特征识别码4日期：2016-07-16日志时间16:09:57
