The OkHttp3ClientHttpRequestFactory caches the request body. When the request body is too large, an OOM occurs.

The OkHttp3ClientHttpRequestFactory caches the request body. When the request body is too large, an OOM occurs.
The RestTemplate is:

  OkHttp3ClientHttpRequestFactory factory =
                new OkHttp3ClientHttpRequestFactory(new OkHttpClient());
            RestTemplate   restTemplate = new RestTemplate(factory);

But when i user OkHttp3Clientto upload this file, it is successful.

My question is why the SimpleClientHttpRequestFactory can set bufferRequestBody?

	@Override
	public ClientHttpRequest createRequest(URI uri, HttpMethod httpMethod) throws IOException {
		HttpURLConnection connection = openConnection(uri.toURL(), this.proxy);
		prepareConnection(connection, httpMethod.name());

		if (this.bufferRequestBody) {
			return new SimpleBufferingClientHttpRequest(connection, this.outputStreaming);
		}
		else {
			return new SimpleStreamingClientHttpRequest(connection, this.chunkSize, this.outputStreaming);
		}
	}

but OkHttp3ClientHttpRequestFactory without this switch?

I want to use the OkHttp3ClientHttpRequestFactory object without caching the request body,How can I do it?

@DInTheName I have also encountered this problem. Have you found a solution？

In the meantime, OkHttp3ClientHttpRequestFactory has been deprecated so I am afraid this issue should be closed for consistency.
