Java – spring rest JSON binding

I'm trying to create restful services with spring

Method accepts the "usercontext" object through parameters, that is, @ requestbody

The client sends JSON objects using the content type "application / JSON" But I received the error "http / 1.1 415 unsupported media type"

.. Even when the client sends an empty "{}" JSON object

My controller:

@Controller
@RequestMapping(value = "/entityService")
class RestfulEntityService {

  @Resource
  private EntityService entityService;

  @ResponseBody
  @RequestMapping(value = "/getListOfEntities",method = RequestMethod.POST)
  public List<Entity> getListOfEntities(@RequestBody UserContext userContext) {
    System.out.println(userContext);
    return null;
  }
}

UserContext. java

public class UserContext {

    private Long userId;

    private String userName;

    private UserAddress userAddress;

    private CustomerInfo customerInfo;

}

Application background:

<bean id="xstreamMarshaller" class="org.springframework.oxm.xstream.XStreamMarshaller"/>
  <bean id="xmlMessageConverter"
        class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
    <constructor-arg ref="xstreamMarshaller"/>
    <property name="supportedMediaTypes" value="application/xml"/>
  </bean>

  <bean id="jsonHttpMessageConverter"
        class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
    <property name="supportedMediaTypes" value="application/json"/>
  </bean>

  <bean
    class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="messageConverters">
      <util:list id="beanList">
        <ref bean="xmlMessageConverter" />
        <ref bean="jsonHttpMessageConverter"/>
      </util:list>
    </property>
  </bean>

  <mvc:annotation-driven/>

He struggled for a while Help will be appreciated!

Solution

Based on what I saw in the messageconverter example of MVC showcase, try using the accept header in the application / JSON request

This is a related question: use spring mvc3 @ ResponseBody had 415 unsupported media type why?
