android - RoboSpice 与 Gson 和 Realm

Question

我正在使用 RoboSpice使用 GsonSpringAndroidSpiceService。我也想加Realm保存数据。

问题是在领域中每个对象都必须扩展领域对象，但 roboSpice 中的 gson 试图解析领域对象而不是忽略它。

我尝试添加排除策略:

Gson gson = new GsonBuilder()
        .setExclusionStrategies(new ExclusionStrategy() {

            @Override
            public boolean shouldSkipField(FieldAttributes f) {
                return f.getDeclaringClass().equals(RealmObject.class);
            }

            @Override
            public boolean shouldSkipClass(Class<?> clazz) {
                return false;
            }
        })
        .create();

然后

    GsonHttpMessageConverter gsonHttpMessageConverter = new GsonHttpMessageConverter(gson);

还尝试(单独)将@expose 添加到对象中的字段，并且

Gson gson = new GsonBuilder().excludeFieldsWithoutExposeAnnotation().create();

在两种方式我有同样的错误:

请帮助我知道为什么会出现此错误以及如何解决

Answer 1

我用了Robospice与 Retrofit和 Realm .
我通过覆盖 createConverter() 解决了它在我的Service扩展类 RetrofitGsonSpiceService .不幸的是，我不能说得更清楚，因为我没有用过GsonSpringAndroidSpiceService .
所以在我的Service类看起来像这样:

@Override
protected Converter createConverter() {
    Gson gson = new GsonBuilder()
            .setExclusionStrategies(new ExclusionStrategy() {
                @Override
                public boolean shouldSkipField(FieldAttributes f) {
                    return f.getDeclaringClass().equals(RealmObject.class);
                }

                @Override
                public boolean shouldSkipClass(Class<?> clazz) {
                    return false;
                }
            })
            .create();

    return new GsonConverter(gson);
}

所以想法是找到Gson可以使用默认配置进行初始化。这就是为什么我将上述配置传递给 Retrofit还。

new RestAdapter.Builder()
               .setConverter(new GsonConverter(gson))
               .build();

希望能帮助到你。
