This is not the right way to extract font. To read font one has to iterate through pdf pages and extract font as below:
这不是提取字体的正确方法。要阅读字体，必须遍历 pdf 页面并提取字体，如下所示：
PDDocument doc = PDDocument.load("C:/mydoc3.pdf");
List<PDPage> pages = doc.getDocumentCatalog().getAllPages();
for(PDPage page:pages){
Map<String,PDFont> pageFonts=page.getResources().getFonts();
}

try
{
PDDocument pddDocument=PDDocument.load("table2.pdf");
PDFTextStripper textStripper=new PDFTextStripper();
System.out.println(textStripper.getText(pddDocument));
textStripper.getFonts();
pddDocument.close();
}
catch(Exception ex)

ex.printStackTrace();

File file = new File("sample.pdf");
PDDocument document = PDDocument.load(file);
for (int i = 0; i < document.getNumberOfPages(); ++i)
{
PDPage page = document.getPage(i);
PDResources res = page.getResources();
for (COSName fontName : res.getFontNames())
{
PDFont font = res.getFont(fontName);
System.out.println(font.getName());
}
}
