Generate word document from bytes in the database

[Tabish58004502]

I am developing an spring boot web application (Java) that automates document generation. One issue that I am facing is I have a a word document template in the database and when a user wishes to generate a document, I want to create a new document using that stored template. So Is there a way to generate a word document from a template whose bytes are stored in the database. Also storing I wish to store this document back to the database by getting it bytes.

Any help would be appreciated.

Hello,

Thank you for your inquiry.
Our Spire.Doc provides loadFromStream and saveToStream methods which allow loading file bytes from database and saving file bytes to the database. Please refer to the following code.

Code: Select all

    //Bytes array from the database
    public static byte[] toDoc(byte[] buff){
        //Converts bytes into a stream
        InputStream inputStream = new ByteArrayInputStream(buff);
        Document doc = new Document();
        //Load stream file
        doc.loadFromStream(inputStream, FileFormat.Docx);

        //...

        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        //Save as a stream file
        doc.saveToStream(bos,FileFormat.Docx);

        //Returns an array of bytes for the stream file
        return  bos.toByteArray();
    }
