Java DOC to PDF Conversion Method with Database Integration

The provided code is a method named 'doc2pdf' that converts a DOC or DOCX file to a PDF file. Here's a breakdown of what the code does:

1. Query the file path of the specified file ID from the database using a mapper.
2. Define the paths for the input DOC/DOCX file and the output PDF file.
3. Download the file from the file system using 'fdfsFileUtils'.
4. Convert the downloaded file from DOC/DOCX to PDF using 'AsposeUtils.Doc2PDF'.
5. Print the file ID and matter ID to the console.
6. Query for an existing attachment using the file ID and matter ID.
7. Generate a new PDF file name based on the original file name.
8. Upload the converted PDF file to the file system using 'fdfsFileUtils'.
9. Delete any existing attachments with the same PDF file name.
10. Create a new attachment record with the PDF file information.
11. Insert the new attachment record and file upload information into the database.

If any exception occurs during the execution of the code, it will be caught and printed to the console.
