在下面的代码中,结果orderObj没有合同编号,订单号详细信息。仅使用连字符对字段进行反序列化。据我所知@jsonproperty应该映射。
请帮助获取我的结果订单中的所有字段。
import com.fasterxml.jackson.annotation.JsonProperty;
public class Order implements Serializable {
private static final long serialVersionUID = 6791737023394030929L;
@JsonProperty("id")
private String id;
@JsonProperty("contract-id")
private String contractId;
@JsonProperty("order-number")
private String orderNumber;
}
final ObjectMapper mapper = new ObjectMapper();
mapper.setAnnotationIntrospector(new JaxbAnnotationIntrospector(mapper.getTypeFactory()));
mapper.configure(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true);
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
mapper.configure(DeserializationFeature.READ_UNKNOWN_ENUM_VALUES_AS_NULL, true);
Response response = orderServiceTarget.queryParam("contract-id",contractId).request().accept(MediaType.APPLICATION_JSON).headers(headersMap).get();
final String serverResponseStr = response.readEntity(String.class);
Order orderObj = objectMapper.readValue(serverResponseStr, Order.class);
结果对象是:它缺少其他字段,
{
"id": "7FABA1724B8F15306447852233",
}
这是服务器响应:
{
"id": "7FABA1724B8F15306447852233",
"contract-id": "42BAD9AAA5231BD",
"order-number": "ADD",
"market-segment": "COM",
}
答案 0 :(得分:1)
如评论中所述,您的ObjectMapper
似乎已配置为使用JaxbAnnotationIntrospector
,它将寻找例如@XmlElement
,而不是@JsonProperty
。 id
字段仍然有效,因为其字段名称在JSON和Java之间匹配。
您只需删除以下行就能解决此问题:
mapper.setAnnotationIntrospector(new JaxbAnnotationIntrospector(mapper.getTypeFactory()));
