如何在使用Retrofit2和Gson转换器进行序列化时防止转义

public class User {
    @SerializedName("user_name")
    private String userName;

    // Getter and Setter
}

public class UserAdapter extends TypeAdapter<User> {
    @Override
    public void write(JsonWriter out, User value) throws IOException {
        // 自定义序列化逻辑
        out.beginObject();
        out.name("user_name");
        out.value(value.getUserName());
        out.endObject();
    }

    @Override
    public User read(JsonReader in) throws IOException {
        // 自定义反序列化逻辑
        User user = new User();
        in.beginObject();
        while (in.hasNext()) {
            String name = in.nextName();
            if (name.equals("user_name")) {
                user.setUserName(in.nextString());
            }
        }
        in.endObject();
        return user;
    }
}

Gson gson = new GsonBuilder()
    .registerTypeAdapter(User.class, new UserAdapter())
    .create();

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("http://example.com")
    .addConverterFactory(GsonConverterFactory.create(gson))
    .build();
