LJW_WEB: 还是老哥这个稳妥，踩了好几个坑，乱码、中文丢数据、才在这里跳过去了

Zeit丶浅白: 确实优雅又简单许多，多谢

gzz_gzz: 这样是不是稍微的优雅一点点 [code=java] public class FileChannelTest { public static void main(String[] args) throws IOException { RandomAccessFile raFile = new RandomAccessFile("d:/soft/AsyncFileChannelDemo.java", "rw"); FileChannel fChannel = raFile.getChannel(); ByteBuffer byteBuffer = ByteBuffer.allocate(32); CharBuffer charBuffer = CharBuffer.allocate(32); while ((fChannel.read(byteBuffer)) != -1) { byteBuffer.flip(); StandardCharsets.UTF_8.newDecoder().decode(byteBuffer, charBuffer, true); charBuffer.flip(); while (charBuffer.hasRemaining()) { // System.out.print("--"); System.out.print(charBuffer.get()); } byteBuffer.compact(); charBuffer.clear(); } raFile.close(); } } [/code]

半世沁心: 说的对,可以调用compact()方法，不使用clear()方法 [code=java] public static void main(String[] args) throws IOException { Charset charset = StandardCharsets.UTF_8; CharsetDecoder decoder = charset.newDecoder(); RandomAccessFile aFile = new RandomAccessFile("D:\\Code\\oneself\\netty\\src\\main\\resources\\nio-data.text", "rw"); FileChannel inChannel = aFile.getChannel(); ByteBuffer buf = ByteBuffer.allocate(32); CharBuffer cuf = CharBuffer.allocate(32); int bytesRead = inChannel.read(buf); while (bytesRead != -1) { buf.flip(); decoder.decode(buf,cuf,true); cuf.flip(); char[] chars = new char[cuf.length()]; cuf.get(chars,0,cuf.length()); System.out.println(new String(chars)); buf.compact();//(该方法清除被读取的缓冲区,没有读取的会放在缓冲区首部) cuf.clear(); bytesRead = inChannel.read(buf); } aFile.close(); } [/code]

格子er: 配置静态ip前可以上网，配置完就上不了网了
