下載MySQL資料庫connector-java

匯入mysql驅動到專案中

右鍵–>build path

選擇Add External JARS，再新增剛下載好的connector

新增程式碼測試連線能否成功

import java.sql.*;
public class test {
public static void main(String args[])
{

    //載入JdBC驅動
    try {
        Class.forName("com.mysql.jdbc.Driver");
        System.out.println("load Driver successfully"
 
);
    } catch (Exception e) {
        System.out.println("load  Driver error");
        e.printStackTrace();
    }


    //連線資料庫
    try {
        Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","liangxi333");
        //jdbc:mysql://localhost:埠號/資料庫名稱","使用者名稱","密碼"
 

        System.out.println("connect sql successfully");
    } catch (Exception e) {
        System.out.println("connect sql erro");
        e.printStackTrace();
    }



}
}

測試成功！！！！！
