java - java的ADAL4j代理问题

Question

我正在尝试使用adal4j@1.6.4java 库与 azure 连接以获取访问令牌。我的应用程序位于公司代理后面，因此我必须设置代理才能连接到 azure。

以下是代码片段

String url = "https://login.microsoftonline.com/tenant_id/oauth2/authorize";
authContext = new AuthenticationContext(url,false, service);
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxyhostname", 8080));
authContext.setProxy(proxy);
ClientCredential clientCred = new ClientCredential(XXXX, xxxx);
Future future = authContext.acquireToken(clientCred,null);
authResult = future.get();

当我使用代理连接时，我收到证书错误。
