私が開発したREST APIに接続しているアンドロイドアプリケーションを開発中です。私はJerseyとHibernateを使ってREST APIを開発しました。このAPIには、findPatientByIdというメソッドがあります。以下は、そのコード...."JsonParseException：Unparseable date：" - Androidエラー
休憩コール ----
@GET
@Path("/findPatientById/{idPatient}")
@Produces(MediaType.APPLICATION_JSON)
public Patient findPatientById(@PathParam("idPatient")int idPatient){
PatientService patientService = new PatientService();
Patient patient = patientService.findPatientById(idPatient);
return patient;
}
データベースレイヤ ---
public Patient findPatientById(int idPatient, Session session) {
Patient patient = (Patient) session.get(Patient.class, idPatient);
return patient;
}
サービス層 ---です -
以下はpublic Patient findPatientById(int idPatient) {
Session session = patientDAOInterface.openCurrentSession();
Transaction transaction = null;
Patient patient = new Patient();
try {
transaction = patientDAOInterface.openTransaction(session);
patient = patientDAOInterface.findPatientById(idPatient, session);
System.out.println("DATE CREATED - "+patient.getDateCreated());
transaction.commit();
} catch (Exception ex) {
ex.printStackTrace();
} finally {
session.close();
Language language = new Language();
if (patient.getLanguage() != null) {
Integer idlanguage = patient.getLanguage().getIdlanguage();
language.setIdlanguage(idlanguage);
patient.setLanguage(language);
}
if (patient.getDiabetesType() != null) {
DiabetesType diabetesType = new DiabetesType();
Integer iddiabetesType = patient.getDiabetesType().getIddiabetesType();
diabetesType.setIddiabetesType(iddiabetesType);
patient.setDiabetesType(diabetesType);
}
// patient.setDateCreated(null);
// patient.setLastUpdated(null);

return patient;

[OK]を、私はこのRESTメソッドを呼び出すときに、私は以下のJSON出力を取得しています。
{
"idpatient": 86,
"diabetesType": null,
"language": null,
"customId": "CUS790",
"diabetesOther": null,
"firstName": "Nirodha",
"lastName": "Wije",
"email": "[email protected]",
"dob": "2005-10-16",
"parentEmail": "[email protected]",
"gender": "male",
"diagnosedDate": "2016-11-16",
"height": 0,
"weight": 0,
"heightUnit": null,
"weightUnit": null,
"theme": "Lite",
"userName": "ranja",
"password": "N1YL3+M0lnORHnKk0dPN8HYd1IBhWKAGO9Qsop7POgw=",
"dateCreated": 1479311638000,
"lastUpdated": 1479311638000
}
は今、私はREST APIの作業を処理するためのRetrofitを使用しています、私のアンドロイドアプリケーションからメソッドの上に接続しています。以下は、私はREST呼び出しから取得していますDateとTimeStampオブジェクトを変換するために、特定のGSONコンバータを使用しています関連するアンドロイドのコード...
private Patient restcallGetPatient(int idPatient){
GsonBuilder gsonBuilder = new GsonBuilder();
gsonBuilder.registerTypeAdapter(Date.class, new DateTypeDeserializer());
Gson gson = gsonBuilder.create();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(RestCommon.URL)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
PatientEndPoint endPoint = retrofit.create(PatientEndPoint.class);
Call<Patient> call = endPoint.findPatientById(idPatient);
call.enqueue(new Callback<Patient>() {
@Override
public void onResponse(Response<Patient> response, Retrofit retrofit) {
patients=response.body();
Log.d("PROFILE_USER"," PATIENT_DETAILS "+patients.getFirstName());
}
@Override
public void onFailure(Throwable t) {
t.printStackTrace();
Log.d("PROFILE_USER"," PATIENT_ERROR "+t.getMessage());
}
});
return patients;
}
です。私は上記のRetrofitコードでそれを使用しました。それは以下の通りです。
public class DateTypeDeserializer implements JsonDeserializer<Date> {
private String[] DATE_FORMATS = new String[]{
"yyyy-MM-dd'T'HH:mm:ssZ",
"yyyy-MM-dd'T'HH:mm:ss",
"yyyy-MM-dd",
"EEE MMM dd HH:mm:ss z yyyy",
"HH:mm:ss",
"MM/dd/yyyy HH:mm:ss aaa",
"yyyy-MM-dd'T'HH:mm:ss.SSSSSS",
"yyyy-MM-dd'T'HH:mm:ss.SSSSSSS",
"yyyy-MM-dd'T'HH:mm:ss.SSSSSSS'Z'",
"MMM d',' yyyy H:mm:ss a"
};
@Override
public Date deserialize(JsonElement jsonElement, Type typeOF, JsonDeserializationContext context) throws JsonParseException {
for (String format : DATE_FORMATS) {
try {
return new SimpleDateFormat(format, Locale.US).parse(jsonElement.getAsString());
} catch (ParseException e) {
}
}
throw new JsonParseException("Unparseable date: \"" + jsonElement.getAsString()
+ "\". Supported formats: \n" + Arrays.toString(DATE_FORMATS));
}
}
このアンドロイドコードを実行すると、以下の例外が発生します。

ここで重要なことがあります。彼らは以下の通りです。 Patient豆における
lastUpdatedとdateCreatedデータベースにTimestampあります。 NetBeansで私はHibernateの自動POJO生成を行い、それらはjava.util.DateとしてBeanで作成されました。dobは、データベースとBeanの両方でDateオブジェクトです。私はMysqlデータベースを使用しています。
上記の例外により、アンドロイドアプリでREST呼び出しを使用してデータベースからBeanを取得することはできません。私はこれが2つの異なったdate形式の残りの呼び出しのため返されていると確信していますが、それは処理する必要があり、そのため私はカスタムGSONコンバータを適用しました。しかし、私は同じ例外を取得しています。私はさまざまな方法で構築されたカスタムGSONコンバータを示唆する数多くのソリューションを検討しましたが、それでも良いものはありませんでした。
どうすればこの問題を解決できますか？あなたはすべての日付形式が法deserialize()に失敗した後、ロングにJSON値を変換し、new Date(valueAsLong)を返すようにしようとすることができ
タイムスタンプは、とにかくミリ秒 –
で返されますあなたは私のコードを与えることができますあなたのAndroidコードで提案したことを行う方法についての例？ –
