Illegal character in opaque part at index

在我这里主要是因为windows用FileChannel 路径问题，代码如下

ByteBuffer byteBuffer = ByteBuffer.allocate(1024);
FileChannel fileChannel = FileChannel.open(Paths.get(URI.create("file:\\D:\\soft\\doc\\filechanel.txt")) );int readInt = fileChannel.read(byteBuffer);

这里是不对的，不支持反斜杠

file:\\D:\\soft\\doc\\filechanel.txt 或者D:\\soft\\doc\\filechanel.txt

正确应是：

file:/D:/soft/doc/filechanel.txt
