java - Drools，KIEBASE 序列化

Question

我正在使用 drools 6.0.1.Final 使用 maven 创建一个 android 应用程序。

为了减少移动设备的工作量，我决定在我的桌面/服务器上编译规则，然后将编译后的规则打包到移动应用程序中。我的问题是，如果没有指向当前 CLASSPATH 的硬链接，我无法序列化 KieBase。

这是我生成的测试代码：

        KieServices ks = KieServices.Factory.get();
        KieFileSystem kfs = ks.newKieFileSystem();


        File rule = new File(getClass().getClassLoader()
                .getResource("HelloWorld.drl").getPath());
        kfs.write( "src/main/resources/HelloWorld.drl",
                       ks.getResources().newInputStreamResource( rule.toURI().toURL().openStream() ) );

        KieBuilder kieBuilder = ks.newKieBuilder( kfs ).buildAll();
        Results results = kieBuilder.getResults();

        if( results.hasMessages( Message.Level.ERROR ) ){
            for (Message message : results.getMessages()) {
                log.error( message.getText() );
            }
            throw new IllegalStateException( "### errors ###" );
        }

        KieContainer kieContainer =
            ks.newKieContainer( ks.getRepository().getDefaultReleaseId() );

        // CEP - get the KIE related configuration container and set the EventProcessing (from default cloud) to Stream
        KieBaseConfiguration config = ks.newKieBaseConfiguration();
        config.setOption( EventProcessingOption.STREAM );
        KieBase kieBase = kieContainer.newKieBase( config );
        File compiledRuleFile = new File(getClass().getClassLoader()
                .getResource("compiledRules").getPath());

        log.debug(compiledRuleFile.getCanonicalPath());

        //----- Serialization to file "compiledRuleFile" --------------
        Serialization.serialize(kieBase, compiledRuleFile);

        //----- Deserialization to another object on another computer --------------
        kieBase = Serialization.deserialize(KieBase.class, compiledRuleFile);

        KieSession kieSession = kieBase.newKieSession();

然后是序列化器：

public static <T> void serialize(T o, File outputFile)
        throws FileNotFoundException, IOException {
    ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(
            outputFile));
    out.writeObject(o);
    out.close();
}

public static <T> T deserialize(Class<T> klass, File inputFile)
        throws StreamCorruptedException, FileNotFoundException,
        IOException, ClassNotFoundException {
    T t = null;
    ObjectInputStream in = new ObjectInputStream(new FileInputStream(
            inputFile));
    t = klass.cast(in.readObject());
    in.close();
    return t;
}

在 pastebin 上获取序列化文件“compiledRuleFile”：

输出文件有问题的部分：

我怎样才能得到一个可以在任何地方反序列化的“compiledRuleFile”？

尝试从 github repo 运行 createrule.java 测试： https ://github.com/cyrillemortier/drools-serialize 打开控制台输出中提示的文件。
