顺手给你写一个，不谢
public static byte[] getFileBytes(String 路径){
ArrayList bytesList = new ArrayList();
byte[] bytes = new byte[1];
FileInputStream inStream = null;
try{
inStream = new FileInputStream(路径);
while(inStream.read(__1bytes)>0){
bytesList.add(__1bytes[0]);
}
bytes = new byte[bytesList.size()];
for(int i;i<bytes.length;i++){
bytes[i] = bytesList.get(i);
}

    return bytes;
}catch(Exception e){
    e.printStackTrace();
    throw e;
}finally{
    try{
        if(inStream!=null){
            inStream.close();
        }
    }catch(Exception e){
        e.printStackTrace();
    }
}

}
