Now let's talk about how to extract text from product_box. In the first place, I used the following method to extract text:

Cosdocument cosdoc = NULL;

Fileinputstream is = new fileinputstream (File );

Partition parser = new partition Parser (is );//

Parser. parse (); cosdoc = parser. getdocument (); extends textstripper stripper = new extends textstripper (); string doctext = stripper. gettext (New pddocument (cosdoc); every time I extract a PDF file, an exception is thrown: Java. lang. throwable: Warning: You did not close the PDF document. If the document is constructed according to the following method, no exception occurs: fileinputstream is = new fileinputstream (File );

Required textstripper stripper = New Extends textstripper (); Required Document = pddocument. Load(Is ); Stringwriter writer = New Stringwriter (); Stripper. writetext (Invalid document, Writer ); doctext = writer. getbuffer (). tostring ();
