Java- Does pdfBox have an option to open file instead of loading it?

问题

I am using PDFBox in Java to attempt to extract text from the pdf file. This is how I load the file:

PDDocument document = PDDocument.load(new File(path1));

As you can see, it opens the file and loads the stuff inside it. This may cause issue when say I tried to load a file which has 10 million words or text which is huge and it throws an OutOfMemoryException:Java heap space.

I actually tested this and it does throw an error. And the culprit was the line above. Is there a way to open the file but not loading it's content in PDFBox?

I appreciate any suggestion.

回答1:

Use :

PDDocument doc = PDDocument.load(file, MemoryUsageSetting.setupTempFileOnly());

This will setup buffering memory usage to only use temporary files with no restricted size.
