У меня есть следующий вопрос в десериализации с org.codehaus.jackson.map.objectmapper, который не работает для следующего класса. Я не уверен, что идет не так с MultivaluedMap, который я использую. < /P>
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]]]
