gson已经注册了registerTypeAdapter，但是不生效

Question

问题遇到的现象和发生背景

gson已经注册了registerTypeAdapter(Object.class, new TypeAdapter(),但是debug的时候没有还是走的依赖包里自带的read方式

Gson gson = new GsonBuilder().serializeNulls().registerTypeAdapter(new TypeToken<Map<String, Object>>() {}.getType(), new TypeAdapter<Object>() {
            private final TypeAdapter<Object> delegate = new Gson().getAdapter(Object.class);
            @Override
            public void write(JsonWriter out, Object value) throws IOException {
                delegate.write(out, value);
            }

            @Override
            public Object read(JsonReader in) throws IOException {
                JsonToken token = in.peek();
                switch (token) {
                    case BEGIN_ARRAY:
                        List<Object> list = new ArrayList<Object>();
                        in.beginArray();
                        while (in.hasNext()) {
                            list.add(read(in));
                        }
                        in.endArray();
                        return list;

                    case BEGIN_OBJECT:
                        Map<String, Object> map = new LinkedTreeMap<String, Object>();
                        in.beginObject();
                        while (in.hasNext()) {
                            map.put(in.nextName(), read(in));
                        }
                        in.endObject();
                        return map;

                    case STRING:
                        return in.nextString();

                    case NUMBER:
                        //return in.nextDouble();
                        String n = in.nextString();
                        if (n.indexOf('.') != -1) {
                            return in.nextDouble();
                        }
                        return in.nextLong();

                    case BOOLEAN:
                        return in.nextBoolean();

                    case NULL:
                        in.nextNull();
                        return null;

                    default:
                        throw new IllegalStateException();
                }
            }
        }).create();
