Question

我是使用docx4j的新手，我试图了解反向工程XLSX文档。我试图在单元格A1中的工作表中添加注释，然后我使用在线代码生成器并在下面进行了正在进行的工作。我有一个生成CTComments的方法，但我想我需要把它变成一个CommentPart？我调用什么对象来添加CommentPart？

import javax.xml.bind.JAXBException;

import org.docx4j.XmlUtils;
import org.docx4j.openpackaging.packages.SpreadsheetMLPackage;
import org.docx4j.openpackaging.parts.PartName;
import org.docx4j.openpackaging.parts.SpreadsheetML.CommentsPart;
import org.docx4j.openpackaging.parts.SpreadsheetML.WorksheetPart;
import org.xlsx4j.jaxb.Context;
import org.xlsx4j.sml.CTComments;
import org.xlsx4j.sml.CTRst;
import org.xlsx4j.sml.CTXstringWhitespace;
import org.xlsx4j.sml.Cell;
import org.xlsx4j.sml.Row;
import org.xlsx4j.sml.STCellType;
import org.xlsx4j.sml.SheetData;

public class launch {

    public static void main(String[] args)
    {
        try { 

            String outputfilepath = "C:\\temp\\OUT_CreateSimpleSpreadsheet.xlsx";

            SpreadsheetMLPackage pkg = SpreadsheetMLPackage.createPackage();

            WorksheetPart sheet = pkg.createWorksheetPart(new PartName("/xl/worksheets/sheet1.xml"), "Sheet1", 1);
            addContent(sheet);

            pkg.save(new File(outputfilepath));

            System.out.println("\n\n done .. " + outputfilepath);   

        } catch (Exception e) { 
            e.printStackTrace();
        }
    }

    private static void addContent(WorksheetPart sheet) {

        // Minimal content already present
        SheetData sheetData = sheet.getJaxbElement().getSheetData();

        // Now add
        Row row = Context.getsmlObjectFactory().createRow();
        Cell cell = Context.getsmlObjectFactory().createCell();
        cell.setV("1234");
        row.getC().add(cell);


        row.getC().add(createCell("hello world!"));
        //HOW DO I ADD A COMMENT TO THIS CELL?
        sheetData.getRow().add(row);

    }

    private static Cell createCell(String content) {

        Cell cell = Context.getsmlObjectFactory().createCell();

        CTXstringWhitespace ctx = Context.getsmlObjectFactory().createCTXstringWhitespace();
        ctx.setValue(content);

        CTRst ctrst = new CTRst();
        ctrst.setT(ctx);

        cell.setT(STCellType.INLINE_STR);
        cell.setIs(ctrst); // add ctrst as inline string

        return cell;

    }

    public static CTComments createComment() throws JAXBException { 
        String openXML = "<comments>"
                + "<authors>"
                    + "<author>Author</author>"
                +"</authors>"
                + "<commentList>"
                    + "<comment authorId=\"0\" ref=\"A1\">"
                        + "<text>"
                            + "<r>"
                                + "<rPr>"
                                    + "<b/>"
                                    + "<sz val=\"9\"/>"
                                    + "<color indexed=\"81\"/>"
                                    + "<rFont val=\"Tahoma\"/>"
                                    + "<charset val=\"1\"/>"
                                +"</rPr>"
                                + "<t>Thomas: hello world!</t>"
                            +"</r>"
                        +"</text>"
                    +"</comment>"
                +"</commentList>"
            +"</comments>";
    CTComments comments = (CTComments)XmlUtils.unmarshalString(openXML);
    return comments;
    }
}

是的，你走在正确的轨道上。

我已经充实了您的代码并在samples/XlsxAddComment.java提交了一个完整的示例

您将在那里看到如何添加CommentsPart。

还需要VMLPart;每个评论都有一个元素。其中，x：Row和x：Column值必须对应于comment / @ ref。例如，第0行，col 0 = ref A1。

如何使用docx4j向单元格添加CommentPart？
