大家好，又见面了，我是你们的朋友全栈君。 这里用到了java对象的序列化，即要求要转换成Byte数组的对象必须是可序列化的。java代码如下：

/**
* 对象转Byte数组
* @param obj
* @return
* @throws Exception
public static byte[] objectToBytes(Object obj) throws Exception {
logger.debug("objectToString called ");
ByteArrayOutputStream out = new ByteArrayOutputStream();
ObjectOutputStream sOut = new ObjectOutputStream(out);
sOut.writeObject(obj);
sOut.flush();
byte[] bytes = out.toByteArray();
logger.debug(bytes.toString());
return bytes;
* 字节数组转对象
* @param content
* @return
* @throws Exception
public static Object bytesToObject(byte[] bytes) throws Exception {
logger.debug("bytesToObject called ");
