服务器上安装数据库在客户端怎么连接

import java.sql.*;

public class DatabaseConnection {
    public static void main(String[] args) {
        String url = "jdbc:mysql://server_ip:port/database_name";
        String username = "your_username";
        String password = "your_password";

        try {
            // 加载数据库驱动程序
            Class.forName("com.mysql.jdbc.Driver");

            // 建立数据库连接
            Connection connection = DriverManager.getConnection(url, username, password);

            // 执行数据库操作
            Statement statement = connection.createStatement();
            ResultSet resultSet = statement.executeQuery("SELECT * FROM table_name");

            // 处理查询结果
            while (resultSet.next()) {
                // 处理每一行数据
                String column1 = resultSet.getString("column1");
                String column2 = resultSet.getString("column2");
                // ...
            }

            // 关闭数据库连接
            resultSet.close();
            statement.close();
            connection.close();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
