我们如何使用 JDBC 将文件插入/存储到 MySQL 数据库中？

CREATE TABLE Articles(Name VARCHAR(255), Article LONGTEXT);

String query = "INSERT INTO Tutorial(Name, Article) VALUES (?,?)";PreparedStatement pstmt = con.prepareStatement(query);

import java.io.FileReader;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
public class InsertingFileToDatabase {
   public static void main(String args[]) throws Exception {
      //ReGIStering the Driver
      DriverManager.registerDriver(new com.mysql.jdbc.Driver());
      //Getting the connection
      String mysqlUrl = "jdbc:mysql://localhost/sampleDB";
      Connection con = DriverManager.getConnection(mysqlUrl, "root", "passWord");
      System.out.println("Connection established......");
      //Inserting values
      String query = "INSERT INTO Articles(Name, Article) VALUES (?, ?)";
      PreparedStatement pstmt = con.prepareStatement(query);
      pstmt.setString(1, "article1");
      FileReader reader = new FileReader("E:\data\article1.txt");
      pstmt.setCharacterStream(2, reader);
      pstmt.execute();
      pstmt.setString(1, "article2");
      reader = new FileReader("E:\data\article2.txt");
      pstmt.setCharacterStream(2, reader);
      pstmt.execute();
      pstmt.setString(1, "article3");
      reader = new FileReader("E:\data\article3.txt");
      pstmt.setCharacterStream(2, reader);
      pstmt.execute();
      System.out.println("Data inserted......");
   }
}

Connection established......
Data inserted......
