【问题描述】:
我尝试调用以下 webclient 查询:
return webClient
.get()
.uri(uriBuilder -> uriBuilder
.path("/geocode/json")
.queryParam("key", google.getApiKey())
.queryParam("latlng", String.join(
",",
String.valueOf(point.getLat()),
String.valueOf(point.getLng()))
)
.build())
.accept(MediaType.APPLICATION_JSON)
.retrieve()
.onStatus(HttpStatus::isError, RestErrorHandler::manageError)
.bodyToMono(*PlacesSearchResponse.class*);
来自 google 的 REST 操作返回 (https://developers.google.com/maps/documentation/geocoding/overview#GeocodingResponses) 以下对象:
{
"results" : [
{
"address_components" : [
{
"long_name" : "1600",
"short_name" : "1600",
"types" : [ "street_number" ]
}
],
"formatted_address" : "1600 Amphitheatre Parkway, Mountain View, CA 94043, USA",
"geometry" : {
"location" : {
"lat" : 37.4224764,
"lng" : -122.0842499
},
"location_type" : "ROOFTOP",
"viewport" : {
"northeast" : {
"lat" : 37.4238253802915,
"lng" : -122.0829009197085
},
"southwest" : {
"lat" : 37.4211274197085,
"lng" : -122.0855988802915
}
}
},
"place_id" : "ChIJ2eUgeAK6j4ARbn5u_wAGqWA",
"plus_code": {
"compound_code": "CWC8+W5 Mountain View, California, United States",
"global_code": "849VCWC8+W5"
},
"types" : [ "street_address" ]
}
],
"status" : "OK"
}
问题是我无法将其解析到我的班级中:PlacesSearchResponse.class
@Data
@JsonIgnoreProperties(ignoreUnknown = true)
public class PlacesSearchResponse {
public String status;
public String errorMessage;
@JsonProperty(value = "results")
public List<PlacesSearchResult> results;
}
@Data
@JsonIgnoreProperties(ignoreUnknown = true)
public class PlacesSearchResult implements Serializable{
private static final long serialVersionUID = 1L;
@JsonProperty(value = "address_components")
public AddressComponent addressComponents[];
}
@Data
@JsonIgnoreProperties(ignoreUnknown = true)
public class AddressComponent implements Serializable {
private static final long serialVersionUID = 1L;
public String longName;
public String shortName;
@JsonProperty(value = "types")
public String[] types;
}
我找不到任何错误,webclient 没问题,因为当我尝试 bodyToMono(String.class) 时,我正确地看到了这个对象。
【问题讨论】:
-
你的错误是?长名,短名
-
没有解析,对象为空。
-
您是否尝试过删除所有内容并一次解析一个字段,直到您看到它中断的位置?
