java读取文本文件到mysql数据库【示例3】-批量导入文本文件

styxmx

　　1、需求：批量导入文件夹“手机号码归属地”下的所有文本文件，如图：

　　2、java源代码：

package com.insigma.zd.group4.liuchao.jdbc;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
public class ReadConfigureFile3 {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
String driver = "com.mysql.jdbc.Driver";
String url = "jdbc:mysql://localhost:3306/test";
String username = "root";
String password = "1234";
Connection conn = null;
Statement stmt = null;
try {
conn = DriverManager.getConnection(url, username, password);
stmt = conn.createStatement();
} catch (SQLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

File file = new File("D:\\share\\手机号码归属地");//得到所选择文件夹
String path = file.getAbsolutePath();//得到选择文件夹的全路径
String[] files = file.list();//取得文件夹下的所有文件
try {
conn.setAutoCommit(false);//设置数据手动提交，自己管理事务
} catch (SQLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}//
for(int i=0; i<files.length;i++){//遍历文件夹下所有文件
String fileName = files.substring(0, files.lastIndexOf("."));//取得所选文件名
String province = fileName.substring(0,fileName.length()-2);
String cardType = fileName.substring(fileName.length()-2);
FileInputStream fis = null;
try {
fis = new FileInputStream(path+"\\"+files);
InputStreamReader input = new InputStreamReader(fis);
BufferedReader br = new BufferedReader(input);
String line = null;
String sql = null;
String info[] = null;
try {
while((line = br.readLine())!= null){
info = line.split("-");
sql = sql = "insert into telephone(startPhone,endPhone,city,province,cardType)values('"+ info[0] +"','"+info[1]+"','"+info[2]+"','"+province+"','"+cardType+"')";
//stmt.executeUpdate(sql);
stmt.addBatch(sql);
}
stmt.executeBatch();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
//提交事务
conn.commit();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
