According to the documentation, the http.socket.timeoutparameter controls the SO_TIMEOUT value, and:
根据文档，该http.socket.timeout参数控制 SO_TIMEOUT 值，并且：
If this parameter is not set, read operations will not time out (infinite timeout).
如果未设置此参数，则读取操作不会超时（无限超时）。

The accepted answer is not applicable for newer versions of HttpClient. Versions 4.3.X and above use the system default which is usually 60 secs.
接受的答案不适用于较新版本的 HttpClient。4.3.X 及以上版本使用系统默认值，通常为 60 秒。
Taken from HttpClient javadoc.
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

A timeout value of zero is interpreted as an infinite timeout. A negative value is interpreted as undefined (system default).
超时值为零被解释为无限超时。负值被解释为未定义（系统默认值）。
Default: -1
默认值：-1

For Apache HttpClient version 4.x upwards
对于 Apache HttpClient 4.x 以上版本
int timeout = 5*60; // seconds (5 minutes)
RequestConfig config = RequestConfig.custom()
.setConnectTimeout(timeout * 1000)
.setConnectionRequestTimeout(timeout * 1000)
.setSocketTimeout(timeout * 1000).build();
HttpClient httpClient =
HttpClientBuilder.create().setDefaultRequestConfig(config).build();
