杰克逊无法使用连字符对字段进行反序列化

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",
}

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@JsonPropertyid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()));
