我有一個(gè)java SDK，它使用OkHttp客戶端（4.0.0）從服務(wù)器獲取令牌IAM并將令牌返回給應(yīng)用程序。關(guān)系可能是這樣的：Applicaiton Sync call SDK，SDKAsync call IAM。參考這個(gè)答案Java - Retrieving Result from OkHttpAsynchronous GET，the代碼如下：異步類：class BaseAsyncResult<T> {private final CompletableFuture<T> future = new CompletableFuture<>();T getResult() {    try {        return future.get();    } catch (InterruptedException | ExecutionException e) {        e.printStackTrace();    }    return null;}void onFailure(IOException e) {    future.completeExceptionally(e);}void onResponse(Response response) throws IOException {    String bodyString = Objects.requireNonNull(response.body()).string();    future.complete(IasClientJsonUtil.json2Pojo(bodyString, new TypeReference<T>() {}));}}Okhttp 調(diào)用如下：public void invoke(Request request, BaseAsyncResult result) {        okHttpClient.newCall(request).enqueue(new Callback() {            @Override            public void onFailure(@NotNull Call call, @NotNull IOException e) {                result.onFailure(e);            }            @Override            public void onResponse(@NotNull Call call, @NotNull Response response) throws IOException {                result.onResponse(response);            }        });    }該應(yīng)用程序使用 sdk 代碼，如 iasClient 是 okhttp 客戶端的包裝器： BaseAsyncResult<AuthenticationResponse> iasAsyncResult = new BaseAsyncResult(); iasClient.invoke(request, iasAsyncResult); AuthenticationResponse result = iasAsyncResult.getResult();錯(cuò)誤消息：java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to x.x.x.AuthenticationResponse我錯(cuò)過(guò)了什么？
