Convert InputStream to base64 string

Question

There is a way to convert an InputStream to a String, and encode it to base64, right?

In my function, I get InputStream parameter, and need to insert it into the BLOB field in my Oracle database table.

Is there a way to do that?

(My database object contains string field to save the image, but I don't find any way to convert the InputStream to string in base 64 format.)

You can try something like this using the Base64 API.

InputStream finput = new FileInputStream(file); byte[] imageBytes = new byte[(int)file.length()]; finput.read(imageBytes, 0, imageBytes.length); finput.close(); String imageStr = Base64.encodeBase64String(imageBytes); 

Use this:
