使用 Spring 和 JsonTypeInfo 注释将 JSON 反序列化为多态对象模型

I have the following object model in my Spring MVC (v3.2.0.RELEASE) web application:

public class Order {
  private Payment payment;
}

@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = As.WRAPPER_OBJECT)
@JsonSubTypes.Type(name = "creditCardPayment", value = CreditCardPayment.class)
public interface Payment {}


@JsonTypeName("creditCardPayment")
public class CreditCardPayment implements Payment {}

当我将Order类序列化为JSON时，我得到以下结果(这正是我想要的):

{
  "payment" : {
    "creditCardPayment": {
      ...
    } 
}

Unfortunately, if I take the above JSON and try to de-serialise it back into my object model, I get the following exception:

Could not read JSON: Could not resolve type id 'creditCardPayment' into a subtype of [simple type, class Payment] at [Source: org.apache.catalina.connector.CoyoteInputStream@19629355; line: 1, column: 58] (through reference chain: Order["payment"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: Could not resolve type id 'creditCardPayment' into a subtype of [simple type, class Payment] at [Source: org.apache.catalina.connector.CoyoteInputStream@19629355; line: 1, column: 58] (through reference chain: Order["payment"])

My application is configured via Spring JavaConf, as follows:

@Configuration
@EnableWebMvc
public class AppWebConf extends WebMvcConfigurerAdapter {

    @Bean
    public ObjectMapper objectMapper() {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setSerializationInclusion(Include.NON_NULL);
        objectMapper.configure(MapperFeature.DEFAULT_VIEW_INCLUSION, false);
        return objectMapper;
    }

    @Bean
    public MappingJackson2HttpMessageConverter mappingJacksonMessageConverter() {
        MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        converter.setObjectMapper(objectMapper());
        return converter;
    }

    @Bean
    public Jaxb2RootElementHttpMessageConverter jaxbMessageConverter() {
        return new Jaxb2RootElementHttpMessageConverter();
    }

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.add(jaxbMessageConverter());
        converters.add(mappingJacksonMessageConverter());
    }
}

为了进行测试，我有一个带有两个方法的控制器，一个返回HTTP GET请求的命令(这一个有效)，另一个通过HTTP POST接受命令(这一个失败)，例如.

@Controller
public class TestController {

    @ResponseBody
    @RequestMapping(value = "/test", method = RequestMethod.GET)
    public Order getTest() {}

    @RequestMapping(value = "/test", method = RequestMethod.POST)
    public void postTest(@RequestBody order) {}

}

I have tried all suggestions from the various discussions on SO but so far had no luck. Can anyone spot what I'm doing wrong?
