[pysjp]

the value of message is filled by fromMqttMessage,but when JSONs.Mapper.writeValueAsBytes,its return empty json data.

the trace logs as follows:

2016-10-07 16:19:53.061 [nioEventLoopGroup-6-1] TRACE c.g.l.m.c.n.NATSClusterImpl sendToApplication 135 - sendToApplication Message[fixedHeader=MqttFixedHeader[messageType=SUBSCRIBE, dup=false, qos=AT_LEAST_ONCE, retain=false, remainingLength=9], additionalHeader=MqttAdditionalHeader[version=MQTT_3_1, clientId=1234, userName=null, brokerId=1], variableHeader=MqttPacketIdVariableHeader[packetId=1], payload=] 2016-10-07 16:19:53.062 [nioEventLoopGroup-6-1] TRACE c.g.l.m.c.n.NATSClusterImpl sendToApplication 136 - sendToApplication {} 2016-10-07 16:19:53.062 [nioEventLoopGroup-6-1] TRACE c.g.l.m.c.n.NATSClusterImpl sendToApplication 137 - sendToApplication [123, 125]

Hi

Can you give me more information on this issue. It seems to me, you are tring to read message from NATS and failed somehow? And you believed there is a problem in serializing or deserializing json, right?

From the logs, there are no errors and I can't identify the problem. I'll make a quick test ASAP. Mean while more information will be appreciated.

thanks for your reply,When I add following option in JSONs.java,it can be serialized to json corrected with right value. Mapper.setVisibility(PropertyAccessor.FIELD, Visibility.ANY); BTW,when the message which type is subscrble is serializing to json,the field of payload is missing. I can not find the way to fixed it. hope for your reply
