java - Jackson - 如何解析这个字段？

Question

我有以下 JSON(来自 WebService):

{
    "result": "success",
    "users": [{
        "id": 12345,
        "login": "blabla",
        "firstName": "first name here",
        "lastName": "last name here",
        "companyName": "company here",
        "email": "email_here@test.com",
        "phone": "",
        "mobile": "123456789",
        "locations": [{
            "id": 123123,
            "latitude": 23.330196,
            "longitude": -92.026073,
            "timestamp": "2015-08-17T01:43:21+00:00"
        }],
        "status": {
            "message": "Message here",
            "timestamp": "2015-07-31T01:50:51+00:00"
        }
    }, (...)

我还有以下 bean:

@JsonTypeName("user")
public class User implements IdentityInterface
{
    private long id;

    @JsonProperty
    private String firstName;

    (...)

    //How can I anotate this field?
    private double latitude;

    //How can I anotate this field?
    private double longitude;

    (...)
}

我不能只将 @JsonProperty 放入纬度/经度变量中，因为这些值位于 JSON 的“位置”部分内。

如何在此处使用 Jackson 注释纬度/经度字段？

Answer 1

您需要像这样在 User 类中创建位置列表。

@JsonTypeName("user")
public class User implements IdentityInterface
{
    private long id;

    @JsonProperty
    private String firstName;

    (...)

    @JsonProperty
    private List<Location> locations;
}
public class Location{
    private Long id;
    private Double latitude;
    private Double longitude;
    private Date timestamp;

    // Getters and setter
   (...)
}
