是不是不支持crc?

/**
* CRC-16 (多项式 0x8005)
* @param data
* @return
*/
public static byte[] calculate(byte[] data) {
int crc = 0x0000; // 初始值
for (byte b : data) {
crc ^= (b & 0xFF) << 8;
for (int i = 0; i < 8; i++) {
if ((crc & 0x8000) != 0) {
crc = (crc << 1) ^ POLY;
} else {
crc = crc << 1;
}
crc &= 0xFFFF; // 保持16位
}
}
// 将int类型的CRC转为2字节的byte数组（大端序）
return new byte[]{(byte) ((crc >> 8) & 0xFF), (byte) (crc & 0xFF)};
