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 {

for (int i = 0; i < list.size(); i++) {

integers[i] = list.get(i).getCode();

}

jsonGenerator.writeArray(integers, 0, integers.length);

}

}

//反序列化

}

    List<AuthTypeEnum> result = new ArrayList<>();
    Iterator<JsonNode> elements = treeNode.elements();
    while (elements.hasNext()) {
