小编Pét*_*űcs的帖子

我正在使用较新的RX java而不是

Observable.create(new Observable.OnSubscribeFunc<T>() {...});

使用:(由于弃用)

Observable.create(new Observable.OnSubscribe<T>() {...});

(这可能很重要,因为大多数示例,教程,explonation使用旧的......)

好吧,让我们看看我的问题.我有一个Java类,相关部分来自它:

private interface ApiManagerService {

    @FormUrlEncoded
    @POST("/login")
    User getUser(@Field("username") String userName, @Field("password") String password);

}


private static RestAdapter restAdapter = new RestAdapter.Builder()
    .setEndpoint(HOST)
    .setLogLevel(RestAdapter.LogLevel.FULL)
    .build();

private static ApiManagerService apiManager = restAdapter.create(ApiManagerService.class);

public static Subscription login(final String userName, final String password, Observer<User> observer) {
    return Observable.create(new Observable.OnSubscribe<User>() {
        @Override
        public void call(Subscriber<? super User> subscriber) {
            try {

                User user = apiManager.getUser(userName, password);

                subscriber.onNext(user);
                subscriber.onCompleted();

            } catch (RetrofitError e) {
                subscriber.onError(e); …

我有一节课:

@Table(name = "Control")
public class Control extends Model{

   @Column
   private String name;

   [...]

   @Column
   private Map<String, Object> properties;

}

我在这堂课中有其他领域,但我在这里只写了那些足以表明我的问题的东西.

我有一个关于插入的例外:

09-14 22:11:34.542: E/SQLiteLog(11482): (1) table Control has no column named properties

对象可以是String []或String.

如果我不将@Column放在HashMap数据上,那么一切都"好",只有它们没有存储的问题.

所以我的问题是如何解决存储这个hashmap的问题.

我的数据来自API,它总是具有相同的属性:

controls: [
    {
        bundle: "CloseButton",    
        frame: "0,0,25,25"
    },
    {
        referenceKey: "AccelerationGyro",
        name: "Acceleration Sensor",
        bundle: "Gyro",
        properties: {
            axis: "Z"
            observedKey: "brakeState",
            requiedValue: "1"
        },
        channels: {
            CH: "Acceleration"
        }
    },
    {
        referenceKey: "SteeringGyro",
        name: "Steering Sensor",
        bundle: "Gyro",
        properties: {
            axis: …
