使用 Jackson 和消息解析 JSON 文件中的内容时出现问题 JsonMappingException 无法反序列化为 START_ARRAY 令牌

给定以下.json文件:

[
    {
        "name" : "New York",
        "number" : "732921",
        "center" : [
                "latitude" : 38.895111, 
                "longitude" : -77.036667
            ]
    },
    {
        "name" : "San Francisco",
        "number" : "298732",
        "center" : [
                "latitude" : 37.783333, 
                "longitude" : -122.416667
            ]
    }
]

I prepared two classes to represent the contained data:

public class Location {
    public String name;
    public int number;
    public GeoPoint center;
}

...

public class GeoPoint {
    public double latitude;
    public double longitude;
}

以便从中解析内容.json文件我使用Jackson 2.2.x并准备了以下方法:

public static List<Location> getLocations(InputStream inputStream) {
    ObjectMapper objectMapper = new ObjectMapper();
    try {
        TypeFactory typeFactory = objectMapper.getTypeFactory();
        CollectionType collectionType = typeFactory.constructCollectionType(
                                            List.class, Location.class);
        return objectMapper.readValue(inputStream, collectionType);
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}

只要我go 掉center属性，所有内容都可以被解析.然而，当我试图解析地理坐标时，我最终得到了以下错误消息:
