用ByteBufUtil的hexDump(byte[] array)函数将字节数组的内容转换为十六进制表示的字符串
package com.thb;import io.netty.buffer.ByteBufUtil;public class Demo {public static void main(String[] args) {byte[] b = new byte[] {0x68, 0x16, 0x03, 0x04, (byte)0xae};String hexDump = ByteBufUtil.hexDump(b);System.out.println(hexDump);}}
运行输出：
