localhost 拼写可能会出现拼写错误

尝试按以下方式更改它：

private static String url =＆＃34; https://localhost:8080/ipn＆＃34;;

您的客户似乎不信任您呼叫的资源。您必须导入目标资源的公钥

您似乎没有在任何地方设置SSL上下文，因此您的应用程序不知道如何验证已建立的https连接。

您需要在初始化httpClient时进行设置，例如：

socketFactory = new SSLConnectionSocketFactory(sslContext);
httpClient = HttpClients.custom().setSSLSocketFactory(socketFactory).build();
