Spring restTemplate and application/xml;charset=UTF-8

Hi,

I am using 3.0.6.RELEASE and trying to get the XML marshaller to run but I can't seem to get a match to the HTTP header.


For a test I get a JSON response ok:

12:37:22,338 INFO [Jaxb2Marshaller] Creating JAXBContext with classes to be bound [class uk.co.thehub.ota.lib.rest.model.ResultEntity,class uk.co.thehub.ota.lib.rest.model.ResultListEntity,c lass uk.co.thehub.ota.lib.rest.model.ResultBinaryEntity]

This fails with XML response:

I have tried with supportedMediaTypes default but still can't get the client to pickup the response, is there an issue with the charset=UTF-8 or ?

Thank you in advance.

Right I wonder if the error message is a bit misleading. The error maybe due to the fact the I can't Unmarshall the response XML:

<?xml version="1.0" encoding="UTF-8"?>
<result-entity>
<response>NEW</response>
<response-value>KI-131589539514798681</response-value>
<opcode>generateKioskName</opcode>
<id>a78118c4-b2a7-4626-b2b2-5faf848547d7</id>
</result-entity>

javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"result-entity"). Expected elements are <{http://thehub.co.uk/ota/lib/rest/model}requestBinaryEntity>

Problem solved, using :

ResponseEntity<ResultEntity> re = restTemplate.getForEntity(url, ResultEntity.class);

Gives me good JAXB messages.

So the issue was all about mapping XML->Entity NOT mapping HTTP headers->org.springframework.http.converter.xml.Marshallin gHttpMessageConverter

I also switch to Castor for the XML so that I can map the result-entity->ResultEntity
