我在GSON上遇到了一个烦人的问题。
我无法解析此文档：

您可以使用在线工具更好地查看它(即 http://json.parser.online.fr/(
如您所见，"文档"是一个嵌套的 JSON 作为字符串，不知何故，GSON 试图在我认为不应该解析时解析它，我尝试将我的可序列化成员设置为字符串、对象、地图、地图<对象、对象>等，但它们似乎都不起作用。还尝试将其设置为瞬态或删除，以查看 GSON 是否不会打扰解析，但我仍然得到：
com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Unterminated object at line 1 column 72
我想我对反序列化没有太多控制权，因为我使用的是 RestTemplate 的 GsonHttpMessageConverter。 所以我认为这主要是 e GSON 问题而不是 Springs。
我的模型：
public class ShipAsset {
public ShipAsset(String pID, Integer pAssetID,
Integer pShipID, String pDocument, String pAssetType) {
super();
mID = pID;
mAssetID = pAssetID;
mShipID = pShipID;
mDocument = pDocument;
mAssetType = pAssetType;
}
public ShipAsset() {
}
@SerializedName("id")
private String mID;
@SerializedName("assetId")
private Integer mAssetID;
@SerializedName("shipId")
private Integer mShipID;
@SerializedName("document")
private String mDocument;
@SerializedName("assetType")
private String mAssetType;
/* getters and setters */
}
这就是我所说的：
ShipAsset[] oResults = mGson.fromJson(oJSONString, ShipAsset[].class);
有人有什么想法吗？
谢谢
错误必须出在以下三件事之一中：
1(你正在收到一个JSONArray，你正在这样投射，不是吗？
public class RestFactory {
public static ShipAsset[] getShipsAssets(RestClient restClient) throws Exception {
ResponseEntity<ShipAsset[]> response = restClient.getForEntity(
"http://server/rest/yourmethod", ShipAsset[].class);
return response.getBody();
}
}
2(我不确定是否是这样，但是您没有包含所有字段的构造函数，也没有空的构造器。也许是因为不是完整的pojo，Gson的选角不正确。
3(尝试注释字段id和assetType。我很确定，如果您不使用SerializedName注释注释字段，Gson 默认情况下会忽略它。但无论如何，试一试！
祝你好运！
