在HttpClient java中是否有任何方法可以处理HTTP/2 Goaway接收到的IOException？

我在应用程序中进行API调用，在某个时候它随机抛出

java.io.IOException:/149.222.1.1:553232:GOAWAY received

， 使用Java11环境。 是否仍要解决此异常，而不是转移到Http/1.1或其他Http客户端库

这是堆栈跟踪

这是您的代码必须处理的问题

您的客户端正在与HTTP 2.0服务器通信，该服务器已发送GOAWAY帧。这意味着服务器出于某种原因决定关闭连接。客户端唯一能做的就是通过

IOException

告诉调用方

这类似于HTTP 1.x服务器执行TCP重置。。。或者只是断开连接。这些还将导致客户端

IOException

因此，解决方案是捕获

IOException

并处理它；e、 g.向用户报告请求失败，或使用新连接重试HTTP请求

（如果您重试，您需要一些策略来避免客户端代码重复一个永远不会成功的请求。事实上，如果服务器断开连接的原因是过载，那么不明智的重试实际上会让事情变得更糟。）

我怀疑切换到HTTP1.1会有所帮助。我希望您会继续得到“随机”

IOExceptions

。。。用不同的信息。。。从服务器使用HTTP 1.1

HTTPClient中有几个与GOAWAY处理相关的JDK错误，但它们在2018年被标记为已解决。您可以使用此查询查找它们：

• )

我认为，如果您使用的是最新版本的JDK 11，则它们与此无关。

如果服务器决定断开连接，切换客户端库将毫无帮助。
