迁移kakfa到另外一台机器上,配置和以前一模一样,但是发现个诡异的问题:能够往kafka里面写数据,但是读取数据的发生 java.io.EOFException: Received -1 when reading from channel, socket has likely been closed. 搞了一个下午,不断重新编译kafka,不断修改配置,最好发现原来使用的log.dir有问题, 这台机器上的log...
(GatheringByteChannel channel) throws IOException { //在通道中写入 long written = channel.write(buffers); if (written 0) throw new EOFException("Wrote negative bytes to channel. This shouldn't happen."); remaining -= written; //有待写 pending = TransportLayers.hasPendingWrites(channel); ...
read(buffer); if (bytesRead < 0) throw new EOFException(); read += bytesRead; } return read; } receive.complete判断完整性,用size和buffer的position来判断 public boolean complete() { return !size.hasRemaining() && buffer != null && !buffer.hasRemaining(); } 处理暂存状态的响应 client发送...
if(buffer!=null){int bytesRead=channel.read(buffer);if(bytesRead<0)thrownewEOFException();read+=bytesRead;} 然后再来看: 这个complete 方法,是判断 size 已经读满了,并且 内容也已经读满了,那么就表示读取到了一个完整的响应了。 那么这就是完整的拆包和粘包的处理了,大概也就是20行代码,也是很精彩的...
