Jackson JSON Dataformat can not unmarshal what it has marshaled
Hi,
I'm trying to build a solution when I marshal POJO into JSON and send over
JMS to a remote machine. On the remote machine message is also consumed by
a Camel route.
However the JSON on the remote machine is unable to marshal the JSON that
the dataformater created.
To show the error I created a smaller POC where I use a SEDA within the
same camel context and it shows the same error.
Here is the test project https://bitbucket.org/ullgren/jsonmarshaltest
It seems that the unmarshal does not like the fact that the POJO class name
is added as a field. Is there anyway to change this behaviour,
The error I get is:
[/jsonmarshaltest.sendToBackend] SedaConsumer WARN Error

Re: Jackson JSON Dataformat can not unmarshal what it has marshaled
Posted by Pontus Ullgren <ul...@gmail.com>.
A small update. When using the xstream library it successfully unmarshal the
json. However the resulting List is a List of Map, each containing one
element with the class name as key, and not a List or POJOs as one might
expect.

Re: Jackson JSON Dataformat can not unmarshal what it has marshaled
Posted by Pontus Ullgren <ul...@gmail.com>.
Hello again,
Tried adding FAIL_ON_UNKNOWN_PROPERTIES to the object mapper but it did not
help.
I also tried with the gson datamapper with the same result.
What I find strange is that the datamappers can not unmarshal the json they
have them self created. :-/
Apart from that the fact that marshaling a list adds the class name to the
json.
This makes the resulting json very tightly coupled to the implementation.

Re: Jackson JSON Dataformat can not unmarshal what it has marshaled
Posted by Pontus Ullgren <ul...@gmail.com>.
Thanks I will try this.
However I'm still a bit surprised over the way that the unmarshal add the
full name of the POJO class to the JSON.
Not very convenient when sending data to a external system where I do not
have any control over the logic.
Not sure if this is an issue only when useList="true" or if unmarshaling a
separate POJO will also add this data.

Re: Jackson JSON Dataformat can not unmarshal what it has marshaled
Posted by Henryk Konsek <he...@gmail.com>.
Hi,
IMHO We should ignore unknown fields in Jackson by default:
objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,
false);
This is the essential option for Jackson, as JSON is usually not as strict
as XML. I would say that we should add failOnUnknownProperties options to
Jackson data format and default it to 'false'. What do you think?
Cheers!
PS Pontus, you can set the option on the object mapper by yourself as a
workaround.
