JavaFx TableView內容在模糊處理後消失

Question

我創建了一個JavaFX應用程序，該應用程序具有多個TableView以顯示內容，如果運行Jar文件，應用程序可以正常工作。由於我需要將應用程序分發給我的客戶，所以我的代碼應該被混淆。我使用Proguard-4.8來模糊我的代碼。

我已經創建了一個示例TableView構建腳本使用Ant混淆示例jar。

之前混淆遵守罐子只 -

我已經上傳我的完整構建腳本項目在 - - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript.zip

我

混淆後的jar完全運行它。你會發現 -

1. 的build.xml - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/build.xml
2. 編譯的Jar不混淆 - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/Sample.jar
3. 混淆的JAR - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/obfuscated/SampleObfuscated.jar
4. Proguard.map - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/obfuscated/ObfuscatedProguard.map
5. 的Java類 - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/src/TableViewWithButton.java

其他的事情是 - 這是我的build.xml文件 -

<project name="sample" default="cleanBuildPackage" basedir="." xmlns:fx="javafx:com.sun.javafx.tools.ant">

          public static void main(java.lang.String[]); 
        }      
      </proguard> 


    </target> 

    <target name="Movejar" depends="Ofuscating"> 
     <move 
     file="${WorkingFolder}/Obfuscated.jar" 
     tofile="obfuscated/${app.name}Obfuscated.jar" verbose="true" overwrite="true" /> 
    </target> 



    <target name="cleanBuildPackage" depends="Movejar"> 
      <fx:deploy width="800" height="600" nativeBundles="all" outdir="${dist}" outfile="${app.name}"> 
       <fx:info title="${app.name}"/> 
        <fx:application name="${app.name}" mainClass="${main.class}"/> 
        <fx:resources> 
         <fx:fileset dir="${dist}" includes="*.jar"/> 
      </fx:resources> 
     </fx:deploy> 
    </target> 

</project> 

在build.xml文件，如果我添加此行，然後我能看到的TableView內容，但是它不混淆所有公共類和它們的方法。

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

我需要我的項目完全混淆。有沒有其他方法來混淆jar文件，而不使公開的類UN-obfuscated，以便我能夠完全看到TableView文本。

感謝，

我建議嘗試使用PropertyValueFactory的長型：

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()); 
    } 
    });
