如何配置ProGuard的尊重杰克逊模式？ [英] How to configure ProGuard to respect Jackson model?

问题描述

下面的类描述了一个模式，我使用杰克逊2.2 一个以.json文件中读取。

The following class describes a model I read from a .json file using Jackson 2.2.

public class Product {
    public String name;
    public int width;
}

借助摇篮的构建过程调用的 ProGuard的萎缩，混淆发布版本。
当我启动应用程序时出现以下错误信息：

The Gradle build process invokes ProGuard to shrink and obfuscate the release build. When I start the application the following error message occurs:

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: 
  Unrecognized field "name" (class com.example.b.c), 
  not marked as ignorable (0 known properties: ])

如何配置ProGuard的或批注产品类，以便杰克逊仍然有效？

How can I configure ProGuard or annotate the Product class so that Jackson still works?

推荐答案

我要管理，我在我的问题简化的例子。这个问题的解决方案是让干将和制定者中的ProGuard我不得不额外定义的模型类，使杰克逊的工作。

I have to admin that I simplified the example in my question. The solution to the problem was to keep getters and setters in ProGuard which I had to additionally define in model classes to make Jackson work.

-keep public class com.example.models.Product {
  public *** get*();
  public void set*(***);
}
