Публикация JSON в REST API

Я создаю REST API, который будет принимать запросы JSON.

Я тестирую его с помощью CURL:

curl -i -POST -H 'Accept: application/json' -d '{"id":1,"pan":11111}' http://localhost:8080/PurchaseAPIServer/api/purchase

Но получаю следующую ошибку:

HTTP/1.1 415 Unsupported Media Type
Server: Apache-Coyote/1.1
Content-Type: text/html;charset=utf-8
Content-Length: 1051
Date: Wed, 25 Apr 2012 21:36:14 GMT

The server refused this request because the request entity is in a format not supported by the requested resource for the requested method ().

При отладке он даже не попадает в мое действие создания в контроллере.

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.ResponseStatus;

import com.app.model.Purchase;
import com.app.service.IPurchaseService;

@Controller
public class PurchaseController {

    @Autowired
    private IPurchaseService purchaseService;

    @RequestMapping(value = "purchase", method = RequestMethod.GET)
    @ResponseBody
    public final List<Purchase> getAll() {
        return purchaseService.getAll();
    }

    @RequestMapping(value = "purchase", method = RequestMethod.POST)
    @ResponseStatus( HttpStatus.CREATED )
    public void create(@RequestBody final Purchase entity) {
        purchaseService.addPurchase(entity);
    }
}

ОБНОВЛЕНИЕ

Я добавил конфигурацию Джексона в AppConfig.java:

@Configuration
@ComponentScan(basePackages = "com.app")
public class AppConfig {

    @Bean
    public AnnotationMethodHandlerAdapter annotationMethodHandlerAdapter()
    {
        final AnnotationMethodHandlerAdapter annotationMethodHandlerAdapter = new AnnotationMethodHandlerAdapter();
        final MappingJacksonHttpMessageConverter mappingJacksonHttpMessageConverter = new MappingJacksonHttpMessageConverter();

        HttpMessageConverter<?>[] httpMessageConverter = { mappingJacksonHttpMessageConverter };

        String[] supportedHttpMethods = { "POST", "GET", "HEAD" };

        annotationMethodHandlerAdapter.setMessageConverters(httpMessageConverter);
        annotationMethodHandlerAdapter.setSupportedMethods(supportedHttpMethods);

        return annotationMethodHandlerAdapter;
    }
}

Мои GET теперь работают правильно:

curl -i -H "Content-Type:application/json" -H "Accept:application/json" http://localhost:8080/PurchaseAPIServer/api/purchase

HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Content-Type: application/json
Transfer-Encoding: chunked
Date: Thu, 26 Apr 2012 21:19:55 GMT

[{"id":1,"pan":111}]

Но я получаю следующее при попытке POST:

curl -i -X POST -H "Content-Type:application/json" -H "Accept:application/json" http://localhost:8080/PurchaseAPIServer/api/purchaseMe -d "{"id":2,"pan":122}"

HTTP/1.1 400 Bad Request
Server: Apache-Coyote/1.1
Content-Type: text/html;charset=utf-8
Content-Length: 971
Date: Thu, 26 Apr 2012 21:29:56 GMT
Connection: close

The request sent by the client was syntactically incorrect ().

Моя модель:

@Entity
@XmlRootElement
public class Purchase implements Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = 6603477834338392140L;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    private Long pan;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public Long getPan() {
        return pan;
    }

    public void setPan(Long pan) {
        this.pan = pan;
    }

}

Любые идеи, где я пошло не так?

Спасибо
