我的android代码是：
HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
factory.setConnectTimeout(10000);
RestTemplate restTemplate = new RestTemplate(factory);
自android 8起工作正常，但是当我在Android 9中测试该应用程序时，出现此错误：

我解决了删除HttpComponentsClientHttpRequestFactory工厂变量的问题，但未设置超时。我想知道是否还有其他解决方案。
