显示响应图像

Question

I have write the image into httpresponse , I defined the contentType for the image.

response.getOutputStream().write(imageBytes);
response.getOutputStream().flush();

What is the syntax to display this image in jsp?

Answer 1

You can use base64 encoding for this. For this you'll need to encode it as base64 on the server side and embed that on client side as -

<img src="data:png;base64,base64_encoded_image_here"> 

Of course, png can be replaced with appropriate mime_type. The downside it that the image will be part of the HTML content. But there won't be a separate HTTP request for this image.
