将一个student.txt文件的数据导入MySQL数据库中一张student1表中:
import java.io.*;
import java.sql.*;
import java.util.*;
public class TextToDataBase {
/**
* @param args
* 本程序涉及文件IO,字符串分隔StringTokenizer,JDBC,数据库sql语句
*/
public static void main(String[] args) {
Connection con=null;
PreparedStatement pstm=null;
FileReader fr=null;
BufferedReader br=null;
try {
Class.forName("com.mysql.jdbc.Driver");
con=DriverManager.getConnection("jdbc:mysql://localhost:3306/exercise1","root","root");
pstm=con.prepareStatement("insert into student1 (ID,name,age,gendar,score) values(?,?,?,?,?)");
fr=new FileReader("D://Exercise//student.txt");
br=new BufferedReader(fr);
for(int i=0;i <5;i++){
String s=br.readLine();
StringTokenizer st=new StringTokenizer(s);
int ID=Integer.parseInt(st.nextToken());
String name=st.nextToken();
int age=Integer.parseInt(st.nextToken());
String gendar=st.nextToken();
int score=Integer.parseInt(st.nextToken());
pstm.setInt(1,ID);
pstm.setString(2,name);
pstm.setInt(3,age);
pstm.setString(4,gendar);
pstm.setInt(5,score);
pstm.executeUpdate();
}
br.close();
pstm.close();
con.close();
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
注意:将student.txt文件内容建成如下形式:
1 张三 20 male 80
2 lisi 24 female 86
3 wangwu 25 male 93
4 liuliu 36 female 89
5 zhaoqi 29 male 81
