大型流的IOUtils.toString（）的替代方法？

Question

I'm getting a large response stream back from an HTTP request. It's JSON, so I need to convert it to a string for processing. I'm running out of heap space on the call to toString.

Code is as follows:

URLConnection conn = new URL(url + "?query=" + URLEncoder.encode(sparql, "UTF-8") + "&output=JSON").openConnection();
conn.setRequestProperty("Accept-Charset", "UTF-8");
InputStream respStream = conn.getInputStream();
response = IOUtils.toString(respStream, "UTF-8");
respStream.close();

I've tried setting the heap size as large as I can. I can't get the data in smaller chunks easily (but if there's not a better choice, I'll implement that). Any suggestions?

Answer 1

I wound up just requesting the data in smaller chunks, which I should have just done to begin with. This was kind of a stupid question, thanks for taking the time to look at it.
