如何安装JDBC以及如何使用它连接到mysql？

Question

我正在尝试安装JDBC,但我不知道如何,当你只有jar文件时,我将它复制到我的java ext文件夹,但它一直给我一个错误,谁能告诉我如何完成安装驱动程序并使用它？

下面是我使用的代码

import java.sql.*;
   public class Test1
   {
       public static void main (String[] args)
       {
String url = "jdbc:mysql://localhost:3306/sabayafr_sabmah";
String username = "root";
String password = "ma";
Connection connection = null;
try {
    System.out.println("Connecting database...");
    connection = DriverManager.getConnection(url, username, password);
    System.out.println("Database connected!");
} catch (SQLException e) {
    System.err.println("Cannot connect the database!");
    e.printStackTrace();
} finally {
    System.out.println("Closing the connection.");
    if (connection != null) try { connection.close(); } catch (SQLException ignore) {}
}

       }
   }

以下是我得到的回应

Cannot connect to database server

更新#3

C:\Users\AlAsad\Desktop>java -cp .;mysql-connector-java-5.0.8-bin.jar Test1
Connecting database...
Cannot connect the database!
java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/

Closing the connection.

Answer 1

您正在尝试将MySQL与专为Microsoft SQL Server设计的jTDS JDBC驱动程序的URL 连接.这永远不会奏效.即使不是通过将JAR文件放在类路径中来修复当前问题.

你真的需要MySQL JDBC驱动程序.另请参阅此答案以获得简短但完整的教程
