java使用aspose.words实现Word拼接的功能

需求：需要将其他模块生成的各个word汇总成一个整的Word。

参考官方介绍地址：https://apireference.aspose.com/java/words/com.aspose.words/DocumentBuilder

public Document appendDocument(Document mainDoc, Document addDoc, boolean isPortrait) {
　　　　 //设置书签，指定文档拼接的位置
        String bookmark = "插入的位置";
        DocumentBuilder builder = null;
        try {
            builder = new DocumentBuilder(mainDoc);
            BookmarkCollection bms = mainDoc.getRange().getBookmarks();
            Bookmark bm = bms.get(bookmark);
            if (bm != null) {
                builder.moveToBookmark(bookmark, true, false);
                builder.writeln();
                Node insertAfterNode = builder.getCurrentParagraph().getPreviousSibling();
                WordsHandler.insertDocumentAfterNode(insertAfterNode, mainDoc, addDoc);
            }
　　　　　　　//设置纸张大小
            builder.getPageSetup().setPaperSize(PaperSize.A4);
            if (isPortrait) {
                //纵向纸张，
                builder.getPageSetup().setOrientation(Orientation.PORTRAIT); 
                builder.insertBreak(BreakType.SECTION_BREAK_NEW_PAGE);
            } else {
                //横向
                builder.getPageSetup().setOrientation(Orientation.LANDSCAPE);
                builder.insertBreak(BreakType.SECTION_BREAK_NEW_PAGE);
            }
            //builder.insertBreak(BreakType.PAGE_BREAK);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return mainDoc;
    }
