在我的weblogic中，很多线程都被这种方式所困扰，但我无法弄清楚原因。这是堆栈跟踪。我设置了连接的所有超时：
这是堆栈跟踪，我没有看到任何可能导致此卡住线程的代码问题（在帖子末尾）。有什么想法吗？

在通过代理建立到目标的隧道时，请求执行被卡住了。请注意，请求级别套接字超时设置仅适用于完全建立的连接。为了避免这种情况，您可能希望使用客户端构建器的SocketConfig方法或直接在连接管理器上使用#setDefaultSocketConfig将连接管理器级别的默认超时设置为正值
RequestConfig requestConfig = RequestConfig.custom()
.setConnectTimeout(5000)
.setSocketTimeout(5000)
.build();
SocketConfig socketConfig = SocketConfig.custom()
.setSoTimeout(5000)
.build();
CloseableHttpClient client = HttpClients.custom()
.setDefaultRequestConfig(requestConfig)
.setDefaultSocketConfig(socketConfig)
.build();
