我正在尝试在我的应用引擎应用程序中创建一个地理点,但是当我尝试反序列化它时,我收到了这条烦人的消息:
Uncaught exception from servlet
org.codehaus.jackson.JsonParseException: Unexpected end-of-input: expected close marker for OBJECT (from [Source: java.io.StringReader@1a21658; line: 1, column: 0]).
这是我的 JSON 代码:
{
"id": 31,
"name": "pepe",
"mail": "p@p.com",
"password": 123,
"age":10,
"birthday": "01-06-1991",
"desc" : " bla bla",
"gp": {
"latitude": 64.124596,
"longitude": -147.8632
}
}
这是geopoint的声明和我的自定义反序列化方法:
GeoPoint gp;
public GeoPoint getGp() {
return gp;
}
@JsonDeserialize(using = CustomGeoPintDeserializer.class)
public void setGp(GeoPoint gp) {
this.gp = gp;
}
public class CustomGeoPintDeserializer extends JsonDeserializer<GeoPoint> {
@Override
public GeoPoint deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
System.out.println("ENTRA");
ObjectMapper mapper = new ObjectMapper();
JsonNode actualObj = mapper.readValue(jsonParser.getText(), JsonNode.class);
double latitude = actualObj.get("latitude").getDoubleValue();
double longitude = actualObj.get("longitude").getDoubleValue();
return new GeoPoint(latitude,longitude);
}
}
