如何在Play框架中禁用序列化？

Question

我正在使用Play Framework和morphia来部署REST服务。我在Object响应中传递Generic Jackson时收到以下错误

Caused by: com.fasterxml.jackson.databind.JsonMappingException: No serializer found for class java.lang.Object and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: common.ResponseStatusEntity["data"]->entities.Trainer["appointmentNotificaiton"]->entities.notificaitons.AppointmentNotificaiton["data"])

如何在play框架中禁用Serializer验证？

Answer 1

问题是Object没有任何属性，默认情况下Jackson不接受它。要禁用它，您需要配置ObjectMapper，如下所示：

ObjectMapper mapper = new ObjectMapper();
mapper.disable(SerializationFeature.FAIL_ON_EMPTY_BEANS);

但马赫更好的是返回某种SUCCESS对象，明确告诉一切都是OK。
