@XmlJavaTypeAdapter不与杰克逊JSON工作

我使用Spring REST框架和杰克逊JSON@XmlJavaTypeAdapter不与杰克逊JSON工作

<bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> 
<property name="objectMapper" ref="customObjectMapper" /> 
<property name="supportedMediaTypes" value="application/json" /> 
</bean> 
<bean id="customObjectMapper"class="com.rackspace.payment.webapp.utils.JaxbJacksonObjectMapper" /> 

public class JaxbJacksonObjectMapper extends ObjectMapper { 
    @SuppressWarnings("deprecation") 
    public JaxbJacksonObjectMapper() { 
     final AnnotationIntrospector introspector = new JaxbAnnotationIntrospector(); 

     this.configure(org.codehaus.jackson.map.DeserializationConfig.Feature.UNWRAP_ROOT_VALUE, true); 
     super.getDeserializationConfig().withAnnotationIntrospector(introspector); 

     this.configure(org.codehaus.jackson.map.SerializationConfig.Feature.WRITE_NULL_PROPERTIES, false); 
     this.configure(org.codehaus.jackson.map.SerializationConfig.Feature.WRAP_ROOT_VALUE, true); 
     super.getSerializationConfig().withAnnotationIntrospector(introspector); 
    } 
} 


//JXAB element 
@XmlAttribute(name = "createDate") 
@XmlJavaTypeAdapter(CustomDateAdapter.class) 
protected Date createDate;

我所面临的问题是，将显示JSON输出时“CREATEDATE”元素的显示如同串XML适配器类不会被调用，但它在XML输出中工作正常。

我错过了什么？如何以JSON格式调用XmlJavaTypeAdapter。

解决了这个问题，这个环节的帮助http://stackoverflow.com/questions/9517189/spring-mvc-and-jackson-mapping-do-not-return-the-root-element-in -json – spal

下面的代码为我做了伎俩。

ObjectMapper objectMapper = new CustomObjectMapper(ENTITY_WITH_ID_DESERIALIZER); 

    AnnotationIntrospector primary = new JacksonAnnotationIntrospector(); 
    AnnotationIntrospector secondary = new JaxbAnnotationIntrospector(); 
    AnnotationIntrospector pair = new AnnotationIntrospector.Pair(primary, secondary); 

    objectMapper.setAnnotationIntrospector(pair); 

    objectMapper.configure(DeserializationConfig.Feature.USE_ANNOTATIONS, true);
