JAX-RS: PUT/POST with JSON array does not deserialize as typed list


JAX-RS: PUT/POST with JSON array does not deserialize as typed list

around this issue I just discovered that this is a side effect of using CDI Interceptors (at least when using WELD as CDI provider). The proxy class used by the CDI interceptors destroys the Generics information of method parameters.
So the CDI proxy causes
code :
public Response setList(List<MyPojo> pojoList) {
    ...
}
public Response setList(List pojoList) {
    ...
}

I wish this help you Worked it out.
According to gson docs here, you need to split the string into individual elements, and deserialize those seperately.
code :
public abstract class AbstractService<T>{

    public abstract Class<T> getClazz();

    public List<T> deserialize(final String json){
        JsonArray array = parser.parse(json).getAsJsonArray();
        final List<T> entityList = new ArrayList<V>();
        for(final JsonElement jsonElement: array){
            T entity = gson.fromJson(jsonElement, getClazz());
            entityList.add(entity);
        }
        return entityList;
    }
}

fixed the issue. Will look into that further I'm calling a .NET Web Api from an Angular client and I use JSON to serialize / deserialize data. , to @dbc for pointing me in the right direction.
code :
public class NoConverter : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        return false;
    }

    public override bool CanRead { get { return false; } }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }

    public override bool CanWrite { get { return false; } }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }
}

To fix this issue I have been stumbled by this for a while. I have a Spring application and would like to parse the following JSON: , you can define your json structure with a couple of classes
code :
public class MyJson {
  private MyResponse response;
  ...
}

public class MyResponse {
  private List<MyClass> objects;
  ...
}

public class MyClass {
  String name;
  List<CustomProperty> customProperties;
  ...
}
ObjectMapper objectMapper = new ObjectMapper();
MyJson myJson = objectMapper.readValue(json, MyJson.class);
List<MyClass> list =  myJson.getResponse().getObjects();

With these it helps What I did not take into consideration is that CourseWork is not a list, it just has lists inside it as private member variables. To fix my problem I had to change my List ReadJsonFile1(List obj) function back to what I had it earlier in the project T ReadJsonFile1(T obj) Basically just taking all the Lists out and making them normal type of T. I also needed to add DataContract Names to ALL my classes. My DataMembers were fine but since this is a Json Array I needed to add the DataContract above every class like in the Assignment class and also the CourseWork Class, just need to make sure you give your DataContract the correct name.
SOLUTION
code :
List<T> ReadJsonFile1<T>(List<T> obj)
 [DataContract(Name = "coursename")]
  public class CourseWork
  {
[DataContract(Name = "assignments")]
    public class Assignment
     {
