                        String token = "";

                        AsymmetricKeyCredential credential = AsymmetricKeyCredential

                        Future<AuthenticationResult> future = authenticationContext.acquireToken("https://outlook.office365.com",(AsymmetricKeyCredential) credential, null);

                        token = future.get().getAccessToken();

                        Long uuid = UUID.randomUUID().getMostSignificantBits();

                        URL url = new URL(

                        Date date = new Date();

                        SimpleDateFormat ft = new SimpleDateFormat(
                                "E, dd MM yyyy hh:mm:ss zzz");

                        System.out.println("Current Date: " + ft.format(date));
                        String dateString = ft.format(date);

                        con.setRequestProperty("Authorization", "Bearer " + token);

                        if (con.getResponseCode() != 200) {
                            System.out.println(con.getHeaderFields());

                            throw new RuntimeException("Failed : HTTP error code : "
                                    + con.getResponseCode());

                        }

                        BufferedReader br = new BufferedReader(new InputStreamReader(
                                (con.getInputStream())));

                        String output;
                        System.out.println("Output from Server .... \n");
                        while ((output = br.readLine()) != null) {
                            System.out.println(output);
                        }

                        con.disconnect();

                        service.shutdown();
                    } catch (Exception e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }

}

我在以下行收到错误消息：

Future<AuthenticationResult> future = authenticationContext.acquireToken("https://outlook.office365.com",(AsymmetricKeyCredential) credential, null);

当我查看它时，我发现在 AuthenticationContext.java 的第 382 行。我们正在调用 JwtHelper class 的 buildJwt 方法，它正在调用 AdalJWTClaimsSet class，它正在扩展 JWTClaimsSet class.

JWTClaimsSet class 不再是 public 现在是最终的。

我使用早期版本的 JWT jar，但我不断收到其他错误。

Answer 1

ADAL 依赖于 oauth2-oidc-sdk 版本 4.5，它依赖于 nimbus-jose-jwt 版本 3.1.2。它有 JWTClaimsSet class 作为 public。您是否在 pom.xml 中覆盖了这些库的版本？您可以在 https://github.com/AzureAD/azure-activedirectory-library-for-java/tree/master/src/samples 试用示例并查看 adal4j 按预期工作。
