统计word页数

统计docx页数

- 方式一：Spire.Doc
- 方式二：jacob
- 方式三：先将docx转成pdf,然后统计PDF页数

前段时间接手一个项目要求导出word打印双面，由于导出的word是由多个word拼接而成，客户又要求每个模块的第一页必须在上面，所以必须将每一个word的页数统计出来，当word页数为奇数时则新增一个空白页，所以简单的吧统计word的页数错误方法和可使用方法罗列一些
错误方式：
1、

	Document document=new Document("C:\Users\73909\Desktop\temporary.docx");
    int pageCount = document.getPageCount();

2、

	FileInputStream in = new FileInputStream("C:\Users\73909\Desktop\temporary.docx");
    OPCPackage open = OPCPackage.open(in);
    XWPFDocument document = new XWPFDocument(open);
    int pages = document.getProperties().getExtendedProperties().getUnderlyingProperties().getPages();

3、

 	Document document=new Document("C:\Users\73909\Desktop\temporary.docx");
    int pages = document.getBuiltInDocumentProperties().getPages();

这三种方式有时候把我两页的word统计成一页有时候统计成三页不建议使用，可以尝试使用下面三种方式

方式一：Spire.Doc

Maven：

       e-iceblue 
      spire.doc.free
      5.2.0

配置镜像

    
      com.e-iceblue
      http://repo.e-iceblue.cn/repository/maven-public/
    

Gradle：implementation "e-iceblue:spire.office.free:5.2.0"
配置镜像
maven {
        url "https://repo.e-iceblue.cn/repository/maven-public/"
    }

	import com.spire.doc.Document;

	public class DemoAction {
	  public static void main(String[] args)  {
	    Document d=new Document("C:\Users\73909\Desktop\temporary.docx");
	    int pageCount = d.getPageCount();
	    System.err.println("docx页数："+pageCount);
	  }
	}

方式二：jacob

此方式需要用到office组件，需要在jdk的bin中放入适合电脑系统的
jacob-1.14.3-x64.dll

依赖：

  net.sf.jacob-project
  jacob
  1.14.3

import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;

public class DemoAction {
  public static void main(String[] args){
    // 建立ActiveX部件
    ActiveXComponent wordCom = new ActiveXComponent("Word.Application");
    //word应用程序不可见
    wordCom.setProperty("Visible", false);
    // 返回wrdCom.Documents的Dispatch
    Dispatch wrdDocs = wordCom.getProperty("Documents").toDispatch();
    // 调用wrdCom.Documents.Open方法打开指定的word文档，返回wordDoc
    Dispatch wordDoc = Dispatch.call(wrdDocs, "Open", "C:\Users\73909\Desktop\temporary.docx", false, true, false).toDispatch();
    Dispatch selection = Dispatch.get(wordCom, "Selection").toDispatch();
    int pages = Integer.parseInt(Dispatch.call(selection,"information",4).toString());
    System.err.println("docx页数："+pages);
    //关闭文档且不保存
    Dispatch.call(wordDoc, "Close", new Variant(false));
    //退出进程对象
    wordCom.invoke("Quit", new Variant[] {});
  }
}

方式三：先将docx转成pdf,然后统计PDF页数

依赖：

  org.apache.pdfbox
  pdfbox
  2.0.24


  com.aspose
  aspose-words
  18.10

aspose-words-15.8.0-jdk16.jar生成PDF会生成水印所以我们需要先把水印给它去掉
