有谁用过iText7，如何合并pdf？

[zyx407703809]

网上看到很多iText的合并，但是iText7方法全都换了，官方api是英文的，小白看不大懂，所以也搞不明白合并pdf到底都需要哪些方法，有没有大神指点一下小弟，当然有具体的例子最好啦！~

PdfDocument pdf = new PdfDocument(new PdfWriter(dest));
PdfMerger merger = new PdfMerger(pdf);

//Add pages from the first document
PdfDocument firstSourcePdf = new PdfDocument(new PdfReader(SRC1));
merger.merge(firstSourcePdf, 1, firstSourcePdf.getNumberOfPages());

//Add pages from the second pdf document
PdfDocument secondSourcePdf = new PdfDocument(new PdfReader(SRC2));
merger.merge(secondSourcePdf, 1, secondSourcePdf.getNumberOfPages());

firstSourcePdf.close();
secondSourcePdf.close();
pdf.close();
