Apache POI将自定义(扩展)属性添加到docx和段落

标签: java apache-poi xwpf

我想使用Apache POI将文件从* .fidus(Fidus Writer)平台转换为* .docx格式,反之亦然。

在* .fidus文件中,我需要将一些属性存储为* .docx文件中的扩展或自定义属性,然后当我想将其转换回* .fidus时,我可以检索它们。

因此,我想知道如何使用POI的类CustomProperties或类似的东西来添加一些属性到docx文件。还可以使用POI将自定义属性(扩展属性)添加到docx文件中的段落吗?

提前致谢。

由于*.docx文档基于XML,我们必须使用POIXMLProperties.CustomProperties,请参阅http://poi.apache.org/apidocs/org/apache/poi/POIXMLProperties.CustomProperties.html

示例:

import java.io.*;
import org.apache.poi.*;
import org.apache.poi.xwpf.usermodel.*;

import org.openxmlformats.schemas.officeDocument.x2006.customProperties.CTProperty;

import java.util.GregorianCalendar;

public class DocumentProperties {

 public static void main(String[] args) throws IOException {

  XWPFDocument document = new XWPFDocument(new FileInputStream("This is a Test.docx"));

  POIXMLProperties properties = document.getProperties();
  //http://poi.apache.org/apidocs/org/apache/poi/POIXMLProperties.html

  //prints the core property Creator:
  System.out.println(properties.getCoreProperties().getCreator());

  //prints the extendend property Application:
  System.out.println(properties.getExtendedProperties().getApplication());

  //sets a custom property
  POIXMLProperties.CustomProperties customproperties = properties.getCustomProperties();
  if (!customproperties.contains("Test")) {
   customproperties.addProperty("Test", 123);
  }
  CTProperty ctproperty = customproperties.getProperty("Test");
  System.out.println(ctproperty);
  System.out.println(ctproperty.getI4());

  //the above customproperties.addProperty() can only set boolean, double, integer or string properties
  //the CTProperty contains more possibitities
  if (!customproperties.contains("Test Date")) {
   customproperties.addProperty("Test Date", 0);
   ctproperty = customproperties.getProperty("Test Date");
   ctproperty.unsetI4();
   ctproperty.setFiletime(new GregorianCalendar(2016,1,13));
  }
  ctproperty = customproperties.getProperty("Test Date");
  System.out.println(ctproperty);
  System.out.println(ctproperty.getFiletime());


  FileOutputStream out = new FileOutputStream(new File("This is a Test.docx"));
  document.write(out);
 }
}

POIXMLProperties.CustomProperties.addProperty()只能设置布尔值,双精度,整数或字符串属性,但基础CTProperty包含更多可能性。

对于CTProperty,请参阅http://grepcode.com/file/repo1.maven.org/maven2/org.apache.poi/ooxml-schemas/1.1/org/openxmlformats/schemas/officeDocument/x2006/customProperties/CTProperty.java#CTProperty
