Java &引用；JsonParseException:不可解析的日期："；-安卓错误

我正在开发一个android应用程序，它连接到我开发的RESTAPI。我使用

Jersey

和

Hibernate

开发了restapi。在这个API中，我有一个名为

findPatientById

的方法。下面是它的代码

休息通话 ----

    public Patient findPatientById(@PathParam("idPatient")int idPatient){

        Patient patient = patientService.findPatientById(idPatient);
        return patient;

public Patient findPatientById(int idPatient, Session session) {
        Patient patient = (Patient) session.get(Patient.class, idPatient);

好的，当我调用这个REST方法时，我得到下面的

JSON

输出

{
  "idpatient": 86,
  "diabetesType": null,
  "language": null,
  "customId": "CUS790",
  "diabetesOther": null,
  "firstName": "Nirodha",
  "lastName": "Wije",
  "email": "ni00@gmail.com",
  "dob": "2005-10-16",
  "parentEmail": "niaasa500@gmail.com",
  "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
}

现在，我正在从我的android应用程序连接上述方法，我正在使用

reformation

来处理剩余的API工作。下面是相关的android代码

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;
}

现在，当我执行这个android代码时，我得到了下面的异常

好的，现在有非常重要的事情要注意。它们在下面

Patient

bean中的

lastUpdated

和

dateCreated

是数据库中的

Timestamp

。在NetBeans中，我为

Hibernate

自动生成了POJO，它们在bean中被创建为

java.util.Date

。

dob

是数据库和bean中的

Date

对象

我正在使用Mysql数据库

因此，由于上述异常，我不可能在android应用程序中使用REST调用从数据库检索bean。我很确定这是由于rest调用返回的两种不同的

date

格式造成的，但这应该得到处理，这就是我应用自定义

GSON

转换器的原因。但是没有用，我得到了同样的例外。我研究了大量的解决方案，这些解决方案建议以各种方式构建定制的GSON转换器，但仍然没有效果

如何解决此问题？

在方法

反序列化（）中所有日期格式失败后，您可以尝试将JSON值转换为Long并返回
新日期（valueAsLong）
：

代替

throw new JsonParseException("Unparseable date: \"" + jsonElement.getAsString()
            + "\". Supported formats: \n" + Arrays.toString(DATE_FORMATS));

写

但我认为问题出在服务器端。它不应以毫秒为单位返回日期。
尝试将实际日期放入日期格式化程序：

Timestamp stamp = new Timestamp(jsonElement.getAsString());
      Date date = new Date(stamp.getTime());

然后在此行中使用
date
：

return new SimpleDateFormat(format, Locale.US).parse(date);

时间戳以毫秒为单位返回。无论如何，你能给我一个关于如何执行你在我的Android代码中建议的操作的代码示例吗？@PeakGen我在哪里添加了一个示例？
