HttpComponent 客户端的默认超时

根据文档，该参数控制SO_TIMEOUT值，并且：http.socket.timeout

如果未设置此参数，则读取操作将不会超时（无限超时）。

接受的答案不适用于较新版本的 HttpClient。版本4.3.X及更高版本使用系统默认值，通常为60秒。

取自HttpClient javadoc。

public int getSocketTimeout()
Defines the socket timeout (SO_TIMEOUT) in milliseconds, which is the timeout for waiting for data or, put differently, a maximum period inactivity between two consecutive data packets).
A timeout value of zero is interpreted as an infinite timeout. A negative value is interpreted as undefined (system default).

Default: -1
