org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/xml;charset=UTF-8' not supported

Question

I am getting below exception when I am calling rest service.

org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/xml;charset=UTF-8' not supported at org.springframework.web.servlet.mvc.method.annotation.AbstractMessageConverterMethodArgumentResolver.readWithMessageConverters(AbstractMessageConverterMethodArgumentResolver.java:152) [spring-webmvc-4.1.1.RELEASE.jar:4.1.1.RELEASE] at org.springframework.web.servlet.mvc.method.annotation.RequestResponseBodyMethodProcessor.readWithMessageConverters(RequestResponseBodyMethodProcessor.java:181) [spring-webmvc-4.1.1.RELEASE.jar:4.1.1.RELEASE] at

Code

    //    This method calls the rest service


        @Override
        public TransactionSearchResults callSearchTransactions(TransactionSearchCriteria criteria, int page, int size) {

        HttpEntity<TransactionSearchCriteria> requestEntity = new HttpEntity<TransactionSearchCriteria>(criteria, getCommonHeaders(new HttpHeaders()));

        Map<String, Integer> params = new HashMap<String, Integer>();
        params.put("size", size);
        params.put("page", page);

        return restTemplate.exchange(urlBase + "/transaction?size={size}&page={page}", HttpMethod.POST, requestEntity, TransactionSearchResults.class, params).getBody();

        }

    // Api which caters to rest call

        @Controller
        @RequestMapping("/transaction")
        public class TransactionStatusController extends BaseController { ... }

    //Controller method for rest call 
        @ResponseBody
        @RequestMapping(produces = { MediaType.APPLICATION_JSON_VALUE }, method = RequestMethod.POST , consumes = MediaType.APPLICATION_JSON_VALUE)
            public com.rest.TransactionSearchResults searchTransactions(@RequestParam(value = "page", required = false) Integer page,
// Using request Param to retireve criteria                         
@RequestParam(value = "size", required = false) Integer size, @Valid     @RequestBody com.rest.TransactionSearchCriteria criteria) {
// This gets relevant results and return it to rest call
    return convert(transactionService.search(convert(criteria), page, size));

}

Answer 1

Your controller is implemented such as to accept only JSON values ie consumes = MediaType.APPLICATION_JSON_VALUE ; thus the error which clearly states that XML is not supported.

In case XML is intended type update the controller to include MediaType.APPLICATION_XML or MediaType.APPLICATION_XML_Value

Answer 2

The issue has been resolved. The pom entry given below which was conflicting with jackson core libraries. Just removed it and it all worked fine.

<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
<version>2.4.3</version>
</dependency>
