如何通过Apache Poi添加评论

我正在尝试通过apache poi api向MS Word文档添加评论。

我已经通过使用完成了部分工作：

CTMarkupRange commentStart = paragraph.getCTP().addNewCommentRangeStart();
commentStart.setId(BigInteger.ZERO);
XWPFRun run = paragraph.createRun();
run.setText("text");
CTMarkupRange commentEnd = paragraph.getCTP().addNewCommentRangeEnd();
commentEnd.setId(BigInteger.ZERO);
CTR ctr = paragraph.getCTP().addNewR();
CTMarkup ctMarkup = ctr.addNewCommentReference();
ctMarkup.setId(BigInteger.ZERO);

但是我不知道如何将其链接到真实注释，并且在api文档中也找不到任何相关内容。

有人知道如何解决吗？

回答：

在Office OpenXML Word文档（XWPF）中，注释是CommentsDocument/word/comments.xml*

.docx

ZIP存档中的特殊内容。因此，首先我们需要访问该文档。但是直到现在，它们XWPFdocument只会在创建时读取该软件包的一部分。没有写访问权限，也没有创建该程序包部件的可能性。

因此，我们首先必须提供这样一种可能性，以便/word/comments.xml在* .docx ZIP归档文件中创建程序包部件并对其进行写访问。

在下面的示例中，该方法MyXWPFCommentsDocument createCommentsDocument(XWPFDocument

document)创建包装零件/word/comments.xml及其相关关系。该类MyXWPFCommentsDocument是对该包装部件具有写访问权的包装器类。

public class CreateWordWithComments {
//a method for creating the CommentsDocument /word/comments.xml in the *.docx ZIP archive
 private static MyXWPFCommentsDocument createCommentsDocument(XWPFDocument document) throws Exception {
  OPCPackage oPCPackage = document.getPackage();
  PackagePartName partName = PackagingURIHelper.createPartName("/word/comments.xml");
  PackagePart part = oPCPackage.createPart(partName, "application/vnd.openxmlformats-officedocument.wordprocessingml.comments+xml");
  MyXWPFCommentsDocument myXWPFCommentsDocument = new MyXWPFCommentsDocument(part);
  String rId = "rId" + (document.getRelationParts().size()+1);
  document.addRelation(rId, XWPFRelation.COMMENT, myXWPFCommentsDocument);
  return myXWPFCommentsDocument;
 }
 public static void main(String[] args) throws Exception {
  XWPFDocument document = new XWPFDocument();
  MyXWPFCommentsDocument myXWPFCommentsDocument = createCommentsDocument(document);
  CTComments comments = myXWPFCommentsDocument.getComments();
  CTComment ctComment;
  XWPFParagraph paragraph;
  XWPFRun run;
//first comment
  BigInteger cId = BigInteger.ZERO;
  ctComment = comments.addNewComment();
  ctComment.setAuthor("Axel Ríchter");
  ctComment.setInitials("AR");
  ctComment.setDate(new GregorianCalendar(Locale.US));
  ctComment.addNewP().addNewR().addNewT().setStringValue("The first comment.");
  ctComment.setId(cId);
  paragraph = document.createParagraph();
  paragraph.getCTP().addNewCommentRangeStart().setId(cId);
  run = paragraph.createRun();
  run.setText("Paragraph with the first comment.");
  paragraph.getCTP().addNewCommentRangeEnd().setId(cId);
  paragraph.getCTP().addNewR().addNewCommentReference().setId(cId);
//paragraph without comment
  paragraph = document.createParagraph();
  run = paragraph.createRun();
  run.setText("Paragraph without comment.");
//second comment
  cId = cId.add(BigInteger.ONE);
  ctComment = comments.addNewComment();
  ctComment.setAuthor("Axel Ríchter");
  ctComment.setInitials("AR");
  ctComment.setDate(new GregorianCalendar(Locale.US));
  ctComment.addNewP().addNewR().addNewT().setStringValue("The second comment.");
  ctComment.setId(cId);
  paragraph = document.createParagraph();
  paragraph.getCTP().addNewCommentRangeStart().setId(cId);
  run = paragraph.createRun();
  run.setText("Paragraph with the second comment.");
  paragraph.getCTP().addNewCommentRangeEnd().setId(cId);
  paragraph.getCTP().addNewR().addNewCommentReference().setId(cId);
//write document
  document.write(new FileOutputStream("CreateWordWithComments.docx"));
  document.close();
 }
//a wrapper class for the CommentsDocument /word/comments.xml in the *.docx ZIP archive
 private static class MyXWPFCommentsDocument extends POIXMLDocumentPart {
  private CTComments comments;
  private MyXWPFCommentsDocument(PackagePart part) throws Exception {
   super(part);
   comments = CommentsDocument.Factory.newInstance().addNewComments();
  }
  private CTComments getComments() {
   return comments;
  }
  @Override
  protected void commit() throws IOException {
   XmlOptions xmlOptions = new XmlOptions(DEFAULT_XML_OPTIONS);
   xmlOptions.setSaveSyntheticDocumentElement(new QName(CTComments.type.getName().getNamespaceURI(), "comments"));
   PackagePart part = getPackagePart();
   OutputStream out = part.getOutputStream();
   comments.save(out, xmlOptions);
   out.close();
  }
 }
}

这适用于apache poi 3.17。由于apache poi 4.0.0该ooxml部分被分开。因此必须有：

...
import org.apache.poi.ooxml.*;
...
import static org.apache.poi.ooxml.POIXMLTypeLoader.DEFAULT_XML_OPTIONS;
...
