杰克逊无法用连字符反序列化字段

Jackson unable to deserialize the fields with hyphen

在下面的代码中,生成的 orderObj 没有合同 ID、订单号详细信息。它仅反序列化带有连字符的字段。据我所知@jsonproperty 应该映射。

请帮助获取我的结果 orderObj 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: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",
}

正如评论中所讨论的,您的 ObjectMapper 似乎配置为使用 JaxbAnnotationIntrospector,它将查找例如@XmlElement 而不是 @JsonPropertyid 字段仍然有效,因为它的字段名称在 JSON 和 Java 之间匹配。

您应该可以通过简单地删除此行来解决问题:

mapper.setAnnotationIntrospector(new JaxbAnnotationIntrospector(mapper.getTypeFactory()));
