Question

我需要把黄色的物体放到客户身上,但出于明显的原因,我需要排除电子邮件和密码等领域。

I know play uses GSON (by google?) and you can pass a serializer class when calling the renderJSON() method. However I m rendering different types of classes at once using a container class:

public class JSONContainer {

    public List<User> userList;

    public List<Toy> toyList;

}

For each class it s possible to make a Serializer class implementing GSON s JsonSerializer<...> method. But if I render a JSONContainer object like this: renderJSON(container) how can I pass the serializer classes to the rendering method?

Or is there maybe an easier/better way to do this?

查阅,这一员额给您提供了多种选择。

It would appear that the best option is to the @Expose (com.google.gson.annotations.Expose) annotation to mark the fields that you want to be serialised by Gson. You then need to use the GsonBuilder to specifically only include the @Expose fields.

Alternatively, as you have mentioned in your post, you can simply build your serialisations yourself. If you look at this post, it shows how specific class types are registered against the GsonBuilder, so any object of that found as part of the serialisation will use your specific serialiser.
