所以我知道这已被问了很多,我已经在这里找到答案,但我有一个ddns通过没有IP,我试图通过Java访问我的数据库我的代码如下
package POJOS;
import com.mysql.jdbc.Connection;
import com.mysql.jdbc.Statement;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.logging.Level;
import java.util.logging.Logger;
public class DBConnection
{
private Connection connection;
private Statement statement;
private ResultSet resultSet;
public DBConnection()
{
connectToDB();
}
private void connectToDB()
{
String
driver = "com.mysql.jdbc.Driver",
url = "jdbc:mysql://clubdatabase.ddns.net:8080/programming_club",
userName = "root",
password = "";
try
{
Class.forName(driver);
connection = (Connection) DriverManager.getConnection(url,userName,password);
System.out.println("Connection to server successful!");
}
catch (ClassNotFoundException ex)
{
Logger.getLogger(DBConnection.class.getName()).log(Level.SEVERE, null, ex);
} catch (SQLException ex) {
Logger.getLogger(DBConnection.class.getName()).log(Level.SEVERE, null, ex);
}
}
public static void main(String[] args) {
DBConnection dBConnection = new DBConnection();
}
}
所以如果你输入网址中的地址它会带你到我的服务器我甚至试图把/ phpmyadmin / programming_club但它仍然无法正常工作。有没有人知道为什么?
答案 0 :(得分:-2)
以
创建连接 connection = DriverManager.getConnection(url,username,password)
