Hi, I use Spring Webflux with Spring Boot 3.1.0. I use this code snippet to log my request body on each request, but since Spring 6.0 I have no alternative to this deprecated method (toByteBuffer() ). Could you help me please ?
try (ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream()) {
Channels.newChannel(byteArrayOutputStream).write(dataBuffer.toByteBuffer().asReadOnlyBuffer());
String requestBody = IOUtils.toString(byteArrayOutputStream.toByteArray(), "UTF-8");
log.trace("Request body = {} ", requestBody);
} catch (IOException e) {
e.printStackTrace();
}

The javadoc explains which other method to use.
Use the toByteBuffer(ByteBuffer) method. So create the ByteBuffer yourself. Another option is to use the asInputStream, then use the StreamUtils to copy from the input to the outputstream and then create the String.

@mdeinum Thank you, I managed to do it work with your advices. My code for the others :
try (ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream()) {
byte[] bytes = new byte[dataBuffer.readableByteCount()];
ByteBuffer byteBuffer = ByteBuffer.wrap(bytes, 0, bytes.length);
dataBuffer.toByteBuffer(byteBuffer);
Channels.newChannel(byteArrayOutputStream).write(byteBuffer);
String requestBody = IOUtils.toString(byteArrayOutputStream.toByteArray(), "UTF-8");
exchange.getAttributes().put("ContentCachingRequest", requestBody);
} catch (IOException e) {
e.printStackTrace();
}
Have a good day !

Is there a reason not to use DataBuffer.toString(StandardCharsets.UTF-8); instead of what you have now?

My bad... absolutely no, I haven't seen this method, it does the job. Thank you !

Thanks, @mdeinum. I was going crazy finding alternatives to the deprecated DataBuffer#asByteBuffer. Your comment helped.
