枚举类list序列化与反序列化

//序列化
public class AuthTypeEnumListJsonSerializer extends JsonSerializer<List> {
@Override
public void serialize(List list, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException {
int[] integers = new int[list.size()];
for (int i = 0; i < list.size(); i++) {
integers[i] = list.get(i).getCode();
}
jsonGenerator.writeArray(integers, 0, integers.length);
}
}

//反序列化
public class AuthTypeListEnumJsonDeserializer extends JsonDeserializer<List> {
@Override
public List deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException, IllegalArgumentException {
ArrayNode treeNode = jsonParser.readValueAsTree();
Field field;
try {
field = jsonParser.getCurrentValue().getClass().getDeclaredField(jsonParser.currentName());
} catch (NoSuchFieldException e) {
return null;
}
field.setAccessible(true);
if (!field.getType().equals(List.class)) {
return null;
}

    List<AuthTypeEnum> result = new ArrayList<>();
    Iterator<JsonNode> elements = treeNode.elements();
    while (elements.hasNext()) {
        Integer appCase = elements.next().asInt();
        AuthTypeEnum anEnum = AuthTypeEnum.codeFrom(appCase);
        result.add(anEnum);
    }
    if (result.isEmpty()) {
        return null;
    } else {
        return result;
    }

}
