  • public final class LimitedStreamCopier
extends java.lang.Object

        public final int copyStreams​(java.io.InputStream in,
                             java.io.OutputStream out,
                             long sizeLimit)
                      throws java.io.IOException
        Copy of the the Spring FileCopyUtils, but does not silently absorb IOExceptions when the streams are closed. We require the stream write to happen successfully.

        Both streams are closed but any IOExceptions are thrown

        Parameters:
        in - the stream from which to read content.
        out - the stream to which to write content.
        sizeLimit - the maximum number of bytes that will be copied between the streams before a ContentLimitViolationException will be thrown. A negative number or zero will be deemed to mean 'no limit'.
        Throws:
        java.io.IOException
