【利用ObjectMapper进行序列化和反序列化】

序列化

 ObjectMapper objectMapper = new ObjectMapper();
   String resStrInput = objectMapper.writeValueAsString(weLinkSendGroupMessageInput);
        request.send(resStrInput);
        int code = request.code();
        String body = request.body();

反序列化

 ObjectMapper objectMapper = new ObjectMapper();
  // 配置不需要全部字段对应
  objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,false);
        SendGroupMessageDto sendGroupMessageDto = objectMapper.readValue(body, SendGroupMessageDto.class);
