断点下载出现BufferOverflowException错误

[fxlcy]

RangeDownloader文件 shadowFileBuffer.put(buffer, 0, readLen)可能会出现该问题

解决方法
shadowFileBuffer.put(buffer, 0, readLen)之前加上

if (readLen > shadowFileBuffer.remaining()) {
val size = shadowChannel.size()
val newFileBuffer = shadowChannel
.map(READ_WRITE, current, size)
shadowFileBuffer = newFileBuffer
}
