问题描述
我正在尝试对Javafx项目进行混淆，并且在混淆之后无法打开该项目。搜索了一些解决方案，告诉要添加一些keepname属性，但无法弄清楚该怎么做。我在混淆前后添加了控制器类。我已经将@FXML添加到keep属性仍然收到错误
混淆配置：
classobfuscationdictionary 'C:\Users\User\Desktop\obfuscationClassNames.txt'
-keepattributes Exceptions,InnerClasses,Signature,Deprecated,SourceFile,LineNumberTable,LocalVariable*Table,*Annotation*,Synthetic,EnclosingMethod,'@FXML'
-keepparameternames
-adaptresourcefilecontents **.fxml,**.properties,meta-inf/MANIFEST.MF
-keepclasseswithmembers class * {
*** @javafx.fxml.FXML *;
}
-keepclasseswithmembers public class com.javafx.main.Main,obfuscationexample.ObfuscationExample {
public static void main(java.lang.String[]);
}
Keep - Applications. Keep all application classes,along with their 'main' methods.
-keepclasseswithmembers public class * {
public static void main(java.lang.String[]);
}
Also keep - Enumerations. Keep the special static methods that are required in
enumeration classes.
-keepclassmembers enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
控制器类
public class SampleController extends borderpane implements Initializable {
@FXML
private Button btnEcrypt;
@FXML
private Label lblStatus;
@FXML
private TextField txtEncrypted;
@FXML
private TextField txtInput;
public SampleController() {
FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("Sample.fxml"));
fxmlLoader.setRoot(this);
fxmlLoader.setController(this);
try {
fxmlLoader.load();
} catch (IOException exception) {
throw new RuntimeException(exception);
}
}
public void initialize(URL fxmlFileLocation,ResourceBundle resources) {
assert this.btnEcrypt != null : "fx:id=\"btnEcrypt\" was not injected: check your FXML file 'Sample.fxml'.";
assert this.lblStatus != null : "fx:id=\"lblStatus\" was not injected: check your FXML file 'Sample.fxml'.";
assert this.txtEncrypted != null : "fx:id=\"txtEncrypted\" was not injected: check your FXML file 'Sample.fxml'.";
assert this.txtInput != null : "fx:id=\"txtInput\" was not injected: check your FXML file 'Sample.fxml'.";
}
@FXML
public void handleButtonAction(ActionEvent event) {
EncryptionService service = new EncryptionService();
String text = service.encrypt(this.txtInput.getText());
this.txtEncrypted.setText(text);
String status = messageformat.format("Text ''{0}'' was encrypted.",new Object[] { this.txtInput.getText() });
this.lblStatus.setText(status);
}
}
混淆后
public class A extends borderpane implements Initializable {
public A() {
FXMLLoader fxmlLoader;
(fxmlLoader = new FXMLLoader(getClass().getResource("Sample.fxml"))).setRoot(this);
fxmlLoader.setController(this);
try {
fxmlLoader.load();
return;
} catch (IOException exception) {
throw new RuntimeException(exception);
}
}
public void initialize(URL fxmlFileLocation,ResourceBundle resources) {
if (!a)
throw new AssertionError("fx:id=\"btnEcrypt\" was not injected: check your FXML file 'Sample.fxml'.");
if (!a)
throw new AssertionError("fx:id=\"lblStatus\" was not injected: check your FXML file 'Sample.fxml'.");
if (!a)
throw new AssertionError("fx:id=\"txtEncrypted\" was not injected: check your FXML file 'Sample.fxml'.");
if (!a)
throw new AssertionError("fx:id=\"txtInput\" was not injected: check your FXML file 'Sample.fxml'.");
}
}
