Hihi Teacher Asked At: 1653894227000 In: Spring
ByteArrayResource và ByteArray
Hi mọi người! Trong Spring khi viết 1 API trả về 1 file (hình ảnh,excel,..) thì em thường trả về byte[] của file đó và thêm 1 số header để định xác kiểu dữ liệu của file đó.

Cho em hỏi là việc trả trực tiếp  byte[]  có khác biệt gì so với khi trả về 1 đối tượng ByteArrayResource( byte[]) không ạ ?

Cảm ơn mọi người !

Nhìn vào source code của ByteArrayResource em có thể thấy là nó cũng chỉ là cái wrap lại của byte array, nên 2 cái trả về là tương đương em ạ.
