带有JDBC的java Gluon示例项目无法在iOS设备上运行
我有简单的Gluon+JDBC代码。 我可以在Android设备上连接此代码,但不能在Ipad上连接
我的身材。格拉德尔
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'org.javafxports:jfxmobile-plugin:1.0.6'
}
}
apply plugin: 'org.javafxports.jfxmobile'
repositories {
jcenter()
}
dependencies {
compile 'mysql:mysql-connector-java:5.0.2'
iosRuntime 'mysql:mysql-connector-java:5.0.2'
}
mainClassName = 'com.mtt8.version15'
jfxmobile {
安卓 {
manifest = 'src/安卓/AndroidManifest.xml'
packagingOptions {
exclude 'META-INF/INDEX.LIST'
}
ios {
infoPList = file('src/ios/Default-Info.plist')
forceLinkClasses = ['com.mtt8.**.*', 'com.mysql.**.*']
}
}
}
下面是Java代码:
private static final String serverIP="192.168.3.188";
private static final String DB_DRIVER = "com.mysql.jdbc.Driver";
private static final String DB_CONNECTION = "jdbc:mysql://192.168.3.188:3306/kasse_sql?useUnicode=true&characterEncoding=UTF-8";
private static final String DB_USER = "root";
private static final String DB_PASSWORD = "MYPASSWORD";
public static Connection connection = null;
public static Statement statement = null;
public static String SQL = null;
public static PreparedStatement pst = null;
public static Connection getDBConnection(){
try {
Class.forName("com.mysql.jdbc.Driver");
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
try {
//connection = DriverManager.getConnection(DB_CONNECTION, DB_USER, DB_PASSWORD);
connection = DriverManager.getConnection("jdbc:mysql://192.168.3.188:3306/kasse_sql?user=root&password=MYPASSWORD&useUnicode=true&characterEncoding=UTF-8");
msg.setText("Connection is OK");
return connection;
} catch (SQLException e) {
e.printStackTrace();
msg.setText("Dont Connection");
}
return connection;
}
正如我所说,这段代码可以在Android上运行,但不能在我的Ipad上运行
我在之后出现以下错误/gradlew启动设备

我尝试了不同的连接字符串,但结果是一样的
有人能告诉我为什么我的代码在Ipad上不起作用吗

连接器中使用的编码似乎有变化
这是在iOS上适用于我的最新版本:
对于较新版本(3.1.13+),我发现了与您看到的相同的异常:
最后,您的
build.gradle
文件上有一个输入错误:}
确保这是您设置选项的方式:
