Answer 1

您的 HTTP 客户端已断开连接。

这可能有几个原因：

• 响应请求花了太长时间，客户端放弃了
• 您用客户端无法理解的内容进行了响应
• 最终用户实际上取消了请求
• 发生了网络错误
• ...可能更多

您可以相当轻松地模仿行为：

URL url = new URL("http://example.com/path/to/the/file");

int numberOfBytesToRead = 200;

byte[] buffer = new byte[numberOfBytesToRead];
int numberOfBytesRead = url.openStream().read(buffer);

Answer 2

您的日志指示 ClientAbortException，当您的 HTTP 客户端断开与服务器的连接并且在服务器关闭服务器套接字连接之前发生这种情况时，就会发生这种情况。

Answer 3

我在 Google 缓存 的打开页面上遇到此错误。

我认为，缓存页面（客户端）在页面加载时断开。

您可以使用过滤器上的 try-catch 忽略此错误日志。

Answer 4

Windows 防火墙可能会导致此异常，请尝试禁用它或为端口甚至程序（java）添加规则
