根因分析
套接字读取操作在配置的超时时间内未收到数据，通常由网络延迟、服务器过载或防火墙拦截引起。
English
A socket read operation did not receive data within the configured timeout period, typically due to network latency, server overload, or firewall blocking.
官方文档

-
Increase the read timeout to a reasonable value (e.g., 30 seconds) using socket.setSoTimeout(30000), and implement a retry mechanism with exponential backoff.
-
Check network connectivity with 'ping server-host' and verify server logs for latency or errors; use a connection pool with timeout settings.
无效尝试
常见但无效的做法:
-
60% 失败
This only delays the failure; if the server is unresponsive, the connection will eventually time out, and it may block threads unnecessarily.
-
75% 失败
This can cause infinite loops or resource exhaustion if the server never responds, and may overwhelm the network.
