} catch (IOException e) { e.printStackTrace(); } } 得到的结果是: hell □□hell□□□□ readFully...这个方法会读取指定长度的流,如果读取的长度不够,就会抛出异常 readFully(inputstream,byte[]) readFully(inputstream,byte[],offset,length...) readFully(reader,charp[]) readFully(reader,char[],offset,length) 比如: @Test public void readFullyTest...; InputStream is = IOUtils.toInputStream("hello world"); try { IOUtils.readFully...byte,就会出错了 java.io.EOFException: Length to read: 20 actual: 11 at org.apache.commons.io.IOUtils.readFully

在使用了 readFully() 方法后,我们只需要处理 EOFException(End of File Exception,读到文件末尾了还没读到要求的数据长度) 一种异常就好了。...因此,完整的读流程为:使用 RandomAccessFile 的 readFully + 检查 ?...总结 读取文件数据时,如果使用 RandomAccessFile ,最好用 readFully(byte b[]) 方法读取数据。不管使用什么读方法,都要检查是否读取到了想要的数据,并进行异常处理。
个人根据方法树判断, 可能是: com.xxxx.ap26.gateway.transport.tcp.protocol.TcpHeaderProtocol.readFully(byte[], int...怀疑开发的TCP相关方法实现问题: com.xxxx.ap26.gateway.transport.tcp.protocol.TcpHeaderProtocol.readFully(java.io.InputStream...的时候只read到400个字符,剩余16个read不到,然后就一直在等待状态 (等待不准确, 其实是IO状态,停留的方法为 java.net.SocketInputStream.socketRead0),从readfully...真正有问题的, 实际上是 com.xxxx.ap26.gateway.transport.tcp.protocol.TcpHeaderProtocol.readFully(java.io.InputStream..., 做TCP解析的方法: com.xxxx.ap26.getaway.transport.tcp.protocol.AbstractTcpHeader (xxx.TcpHeaderProtocol.readFully
我们把类的文件成功的转换成流文件DataInputStream,我们是类文件是按照顺序读取的,所以可以定义的游标的对象cursor来读取,对cursor可以封装几个读取的方法: public void readFully...(byte[] byteArr) throws IOException { this.dataInputStream.readFully(byteArr); }...- 获得魔数 Java中的魔数是一个固定的值cafe babe,一共占用4个字节,我们可以通过简单的方式把魔数取出来: byte[] byteArr=new byte[4]; cursor.readFully
block块的长度 byte[] buf = new byte[m_dataFile.readInt()]; // 从数据文件中读取整个block到buf数组 m_dataFile.readFully...byte[] data = new byte[len]; // 从block中读取Message in.readFully
maxMemoryMapBytes) val chunk = allocator(chunkSize.toInt) remaining -= chunkSize JavaUtils.readFully...blockSize < minMemoryMapBytes) { val buf = ByteBuffer.allocate(blockSize.toInt) JavaUtils.readFully...toChunkedByteBuffer()方法会将文件转化为输入流FileInputStream,并获取其ReadableFileChannel,再调用JavaUtils.readFully()方法将从

at com.mysql.jdbc.MysqlIO.readFully .........很明显的,都卡在MysqlIO.readFully也就是数据库读取上,再也不往下走了。 没配超时 这就肯定是没配超时了,排查了下他们的配置,确实没配。之前系统梳理过好多次,但没想到还是有这种漏网之鱼。
fmt.Fprintf(os.Stderr, "Fatal error: %s", err.Error()) os.Exit(1) } } func readFully...err = conn.Write([]byte("GET /api/v3/get HTTP/1.1\r\n\r\n")) checkError(err) result, err := readFully

IOException public void close() throws IOException RandomAccessFile还有另外两个read方法: public final void readFully...(byte b[]) throws IOException public final void readFully(byte b[], int off, int len) throws IOException...IOException{ db.seek(pos); int length = db.readInt(); byte[] data = new byte[length]; db.readFully...(data); return data; } 代码也很简单,定位到指定位置,读取实际长度,然后调用readFully读够内容。
