我正在使用Spring REST框架和Jackson JSON
<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;
我面临的问题是,当JSON输出显示“createDate”元素时,它以字符串形式显示,而XML适配器类未被调用,而在XML输出中它可以正常工作。
我错过了什么?如何在JSON格式中调用XmlJavaTypeAdapter。
