如何使用PDFBox获取PDF中的书签内容的页码数

Question

我正在使用Apache PDFBox版本2.0.x.我正尝试使用书签搜索PDF，当我打开目标时，我应该能够获得书签所指的Pagenumber。这是我的代码打印所有书签。我可以做，如果我的标题搜索文本匹配，那么这是我的目标书签等号像searchText.equals(current.getTitle())

public static void printBookmark(PDOutlineNode bookmark, String indentation) throws IOException { 
    PDOutlineItem current = bookmark.getFirstChild(); 
    COSObject targetPageRef = null; 
    while (current != null) { 
     System.out.println(indentation + current.getTitle());   
     printBookmark(current, indentation + " "); 
     current = current.getNextSibling(); 
    } 
} 

搜索。任何人之前尝试过？

我找到了解决方案。

public static void printBookmark(PDOutlineNode bookmark, String indentation) throws IOException 
{ 
    PDOutlineItem current = bookmark.getFirstChild(); 
    COSObject targetPageRef = null; 
    while (current != null) 
    { 
     System.out.println(indentation + current.getTitle());  
     PDPageFitWidthDestination destination = (PDPageFitWidthDestination) current.getDestination(); 
     System.out.println("Page Number " + destination.retrievePageNumber()); 
     printBookmark(current, indentation + " "); 
     current = current.getNextSibling(); 
    } 

}
