JavaFx TableView 内容在混淆后消失

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，应用程序可以正常工作。因为我需要将应用程序分发给我的客户，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，它可以混淆示例 jar。

混淆之前只编译jar -

混淆后的jar -

我已将完整的构建脚本项目上传到 - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript.zip

我已经完全运行它了。你会发现——

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

其他的事情是—— 这是我的 build.xml 文件 -

             </fx:resources>
         </fx:deploy>
    </target>

</project>

如果我在 build.xml 中添加这一行，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未混淆，以便我能够完全看到 TableView 文本。

谢谢，

我建议尝试使用 PropertyValueFactory 的长格式：

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());
     }
  });
