Kann keinen Deserializer für Nicht-konkrete Kartentypen finden [Kartentyp; Klasse javax.ws.rs.core.multivaluedMap ⇐ Java

[Anonymous]

Ich habe das folgende Problem in der Deserialisierung mit org.codeehaus.jackson.map.objectMapper, der für die folgende Klasse nicht funktioniert. Ich bin mir nicht sicher, was mit der von mir verwendeten MultivaluedMap schief geht. < /P>

Code: Select all

 public class ClassD
{
private ClassA objA;
private ClassB objB;
private final ClassC objC;
private MultivaluedMap headerMap;
}

public static void main(String[] args) {
String fileName = "someFilePath";
mockCollection = fromJSON(new TypeReference() {}, new String(Files.readAllBytes(Paths.get(fileName)), StandardCharsets.UTF_8));
}

public static  T fromJSON(final TypeReference type, final String jsonPacket) throws JsonParseException, JsonMappingException, IOException {
T data = null;
ObjectMapper om = new ObjectMapper();
om.configure(DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);
data = om.readValue(jsonPacket, type);
return data;
}

Exception :
org.codehaus.jackson.map.JsonMappingException: Can not find a deserializer for non-concrete Map type [map type; class javax.ws.rs.core.MultivaluedMap, [simple type, class java.lang.String] -> [collection type; class java.util.List, contains [simple type, class java.lang.String]]]
