Hi all,
I have a quite silly question, probably due to my inexperience with CXF.
Basically, in Syncope we have a set of CXF services producing both XML
and JSON (via Jackson).
At high level, I have troubles when reading JSON payload, via WebClient;
the same input string (received as Payload), when given to a bare
Jackson's ObjectMapper instance, works like a charm.
More in detail, the CXF service configuration is the one at [1].
When issuing, with header "Accept: application/json", an HTTP GET
/syncope/cxf/schemas/user/NORMAL/fullname (e.g. read() as defined at
[2]), it returns
{
"name": "fullname",
"type": "String",
"mandatoryCondition": "true",
"enumerationValues": null,
"enumerationKeys": null,
"multivalue": false,
"uniqueConstraint": true,
"readonly": false,
"conversionPattern": null,
"validatorClass": null
}
which looks correct; in fact I am easily able to deserialize such input via
ObjectMapper mapper = new ObjectMapper();
SchemaTO actual = mapper.readValue(writer.toString(),
SchemaTO.class);
but when I try to use WebClient for accessing the same read() method I
get stuck with
ClassCastException: java.util.LinkedHashMap cannot be cast to
org.apache.syncope.common.to.AbstractSchemaTO
which looks definitely like a Jackson exception.
For additional reference, here is my client's Spring configuration [3]
(see 'restClientFactory') and the AbstractSchemaTO [4] and SchemaTO
classes [5].
Nevertheless to say, switching to "Accept: application/xml" makes
everything work again.
I am using CXF 2.7.6-SNAPSHOT (this in order to be able to use Jackson
2.2.2).
Any hint?
Regards.
