java convert inputStream to base64 string

Question

There is a way to convert inputStream to a String, and encode it to base64, right? In my function, I get InputStream param, and need to insert it into the BLOB field in my Oracl

Answer 1

There is nice way to do this is using IOUtils to convert the InputStream into a Byte Array...

something like

    InputStream is;
    byte[] bytes = IOUtils.toByteArray(is);

Here you can use Base64 to convert Byte Array to String.

Sample Code

    String encoded = Base64.getEncoder().encodeToString(bytes);

Now you can use your String.
