您需要阅读PDF(文件阅读器)，然后才能将该File-object转换为字节数组.这非常简单，因为任何对象都可以转换为字节数组.

You need to read the PDF (filereader), then you can convert that File-object into a byte Array. That is pretty simple, because any object can be converted int a byte array.

public static byte[] getBytes(Object obj) throws java.io.IOException{
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(bos);
oos.writeObject(obj);
oos.flush();
oos.close();
bos.close();
byte [] data = bos.toByteArray();
return data;
}
