我必须使用服务原理将Power BI报表嵌入我的Java应用程序中。所以我试图生成AAD访问令牌。但是我无法生成访问令牌。下面是代码和输出。我也尝试使用Javascript生成aad访问令牌，但无法这样做。请帮忙。

答案 0 :(得分：0)
我使用几乎相同的代码（在最后一天左右）
但是我的代码段看起来像下面的
String authority = "https://login.microsoftonline.com/{your tenant id}";
ExecutorService service = Executors.newFixedThreadPool(1);
AuthenticationContext context = new AuthenticationContext(authority, true, service);
您是否在不允许您访问login.microsoftonline.com的防火墙后面？
您可以使用以下API页面登录并生成报告令牌 https://docs.microsoft.com/en-gb/rest/api/power-bi/embedtoken/reports_generatetokeningroup
