У меня проблема с подключением моего соединения GoDaddy MySQL в приложении javafx для настольных ПК и Android.Я хочу подключиться напрямую к MySQL, расположенному в GoDaddy, без использования технологии ssh.
Это мой файл Main.java:
package com.maqboolsolutions.mysql_ssh_android;
import java.io.IOException;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javafx.application.Application;
import javafx.stage.Stage;
public class Main extends Application {
String HOST = ""; // Hosting provider ip address / name (e.g. example.com)
String DB_NAME = ""; // Database name (e.g. db_test)
String DB_URL = "jdbc:mysql://" + HOST + ":3306/" + DB_NAME;
String USERNAME = ""; // mysql database user name (e.g. admin)
String PASSWORD = ""; // mysql database password (e.g. 123)
@Override
public void start(Stage primaryStage) throws IOException {
getConnection();
}
private void getConnection() {
try {
//mysql database connectivity
Class.forName("com.mysql.cj.jdbc.Driver");
Connection con = DriverManager.getConnection(DB_URL, USERNAME, PASSWORD);
System.out.println("Database connection established");
System.out.println("DONE");
} catch (ClassNotFoundException | SQLException ex) {
Logger.getLogger(DBConnection.class.getName()).log(Level.SEVERE, null, ex);
System.exit(0);
}
}
public static void main(String[] args) {
launch(args);
}
}
Это gradle.build:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'org.javafxports:jfxmobile-plugin:1.3.16'
}
}
apply plugin: 'org.javafxports.jfxmobile'
repositories {
jcenter()
maven {
url 'http://nexus.gluonhq.com/nexus/content/repositories/releases'
}
}
mainClassName = 'com.maqboolsolutions.mysql_ssh_android.Main'
dependencies {
compile 'com.gluonhq:charm:5.0.2'
compile 'mysql:mysql-connector-java:8.0.13'
compile 'com.jcraft:jsch:0.1.54'
}
jfxmobile {
downConfig {
version = '3.8.6'
// Do not edit the line below. Use Gluon Mobile Settings in your project context menu instead
plugins
}
android {
manifest = 'src/android/AndroidManifest.xml'
javafxportsVersion = '8.60.11'
android {
manifest = 'src/android/AndroidManifest.xml'
packagingOptions {
exclude 'META-INF/INDEX.LIST'
}
dexOptions {
javaMaxHeapSize "4g"
}
}
}
}

Я уже добавляю свой IP-адрес в godaddy Удаленный MySQL , как показано.
Если я использую технику ssh, то она работает на рабочем столе, а не на устройстве Android.Смотрите мой пост Javafx android mysql connect over ssh .
