Method Details

setRequestFactory

public void setRequestFactory(ClientHttpRequestFactory requestFactory)

Set the request factory that this accessor uses for obtaining client request handles.

The default is a SimpleClientHttpRequestFactory based on the JDK's own HTTP libraries (HttpURLConnection).

Note that the standard JDK HTTP library does not support the HTTP PATCH method. Configure the Apache HttpComponents or OkHttp request factory to enable PATCH.
