Question

我创建了一个JavaFX应用程序，它有许多TableView来显示内容，如果我运行Jar文件，应用程序工作正常。因为我需要将应用程序分发给我的客户端所以我的代码应该被混淆。我正在使用Proguard-4.8来混淆我的代码。

我使用Ant创建了一个示例TableView构建脚本，该脚本模糊了样本jar。

在混淆之前，仅使用jar -

Before Obfuscation

在混淆Jar之后 -

After Obfuscation

我上传了完整的构建脚本项目 - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript.zip

我完全运行了它。你会发现 -

build.xml - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/build.xml
没有混淆的编译Jar - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/Sample.jar
混淆的Jar - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/obfuscated/SampleObfuscated.jar
Proguard.map - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/obfuscated/ObfuscatedProguard.map
源Java类 - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/src/TableViewWithButton.java

其他事情是 - 这是我的build.xml文件 -

    </target>

</project>

在build.xml中，如果我添加这行，那么我可以看到TableView内容，但它不会混淆所有公共类及其方法。

<keep access="public">
     <method access="public protected" />
</keep>

我需要完全混淆我的项目。有没有其他方法来混淆jar文件而不保持公共类UN-obfuscated，以便我能够完全看到TableView文本。

谢谢，

我建议尝试使用长形式的 PropertyValueFactory ：

col.setCellValueFactory(new Callback<TableColumn.CellDataFeatures<Test, String>,
             ObservableValue<String>>() {
     public ObservableValue<String> call(TableColumn.CellDataFeatures<Test, String> t) {
         // t.getValue() returns the Test instance for a particular TableView row
         return t.getValue().testProperty();
         // or
         return new SimpleStringProperty(t.getValue().getMessage());
     }
  });

混淆后，JavaFx TableView内容消失
