java - Apache POI - 将多个段落添加到同一行的页眉/页脚

Question

我正在使用 Apace POI 处理一些文档，我想添加一个包含多个段落的页眉/页脚，但我希望它们显示在同一行上。

这是我目前的尝试:

XWPFDocument document = new XWPFDocument();

// adding header and footer
CTP ctp = CTP.Factory.newInstance();
CTR ctr = ctp.addNewR();

// create footer components
CTText footerCopyrightText = ctr.addNewT();
footerCopyrightText.setStringValue("\u00A9" + " My Website - " + Calendar.getInstance().get(Calendar.YEAR));

CTText footerPageText = ctr.addNewT();
footerPageText.setStringValue(document.getProperties().getExtendedProperties().getUnderlyingProperties().getPages() + "");

XWPFParagraph footerCopyrightParagraph = new XWPFParagraph( ctp, document );
footerCopyrightParagraph.setAlignment(ParagraphAlignment.CENTER);

XWPFParagraph footerPageParagraph = new XWPFParagraph(ctp, document);
footerPageParagraph.setAlignment(ParagraphAlignment.RIGHT);

XWPFParagraph[] footerParagraphs = {footerCopyrightParagraph, footerPageParagraph};
CTSectPr sectPr = document.getDocument().getBody().addNewSectPr();
XWPFHeaderFooterPolicy headerFooterPolicy = new  XWPFHeaderFooterPolicy(document, sectPr );
headerFooterPolicy.createFooter(STHdrFtr.DEFAULT, footerParagraphs);

但是，到目前为止的最终结果是我得到了一个右对齐的文本，它由两个连接在一起的 XWPFParagraph 组成。

我还在 Stack Overflow 上查看了其他一些示例(有一个用于 Header，但我没能让它工作)。

我想要实现的一个基本想法是:http://imgur.com/jrwVO0F

对我做错了什么有什么想法吗？

谢谢，

添加制表位并使用它们

这是我的草稿 - 在 A4 文档上左、中、右打印我的名字。我完全不知道这些位置元素是如何计算的……添加制表位的代码来自Java Apache POI Tab Stop word document

import java.awt.Desktop;
import java.io.*;
import java.math.BigInteger;

import org.apache.poi.xwpf.usermodel.*;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.*;

public class POIExample {
    public static void main(String[] args) {
        try {
            XWPFDocument document = new XWPFDocument();
            XWPFParagraph paragraph = document.createParagraph();

            XWPFRun tmpRun = paragraph.createRun();
            tmpRun.setText("JAN");
            tmpRun.addTab();
            tmpRun.setText("JAN");
            tmpRun.addTab();
            tmpRun.setText("JAN");

            BigInteger pos1 = BigInteger.valueOf(4500);
            setTabStop(paragraph, STTabJc.Enum.forString("center"), pos1);
            BigInteger pos2 = BigInteger.valueOf(9000);
            setTabStop(paragraph, STTabJc.Enum.forString("right"), pos2);

            File f = File.createTempFile("poi", ".docx");
            try (FileOutputStream fo = new FileOutputStream(f)) {
                document.write(fo);
            }
            Desktop.getDesktop().open(f);

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

    public static void setTabStop(XWPFParagraph oParagraph, STTabJc.Enum oSTTabJc, BigInteger oPos) {
        CTP oCTP = oParagraph.getCTP();
        CTPPr oPPr = oCTP.getPPr();
        if (oPPr == null) {
            oPPr = oCTP.addNewPPr();
        }

        CTTabs oTabs = oPPr.getTabs();
        if (oTabs == null) {
            oTabs = oPPr.addNewTabs();
        }

        CTTabStop oTabStop = oTabs.addNewTab();
        oTabStop.setVal(oSTTabJc);
        oTabStop.setPos(oPos);
    }
