如何使用Java连接到远程MySQL数据库？

Question

谁能为我提供Java SE编码以连接到服务器（而不是本地主机）中的MySQL数据库？ 我应该用什么代替“ localhost”和端口号？

import java.sql.Connection;
import java.sql.DriverManager;

public class Main {
  public static void main(String[] argv) throws Exception {
    String driverName = "org.gjt.mm.mysql.Driver";
    Class.forName(driverName);

    String serverName = "localhost";
    String mydatabase = "mydatabase";
    String url = "jdbc:mysql :// " + serverName + "/" + mydatabase; 

    String username = "username";
    String password = "password";
    Connection connection = DriverManager.getConnection(url, username, password);
  }
}

Answer 1

只需使用

String dbUrl = "jdbc:mysql://your.database.domain/yourDBname";
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection (dbUrl);
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(query);

确保tou有权访问mysql中的远程计算机

给ip而不是your.database.domain
