Apache POI - 在同一行上添加多个段落到页眉/页脚

I am using Apace POI to process some documents and I would like to add a header/footer which would consist of multiple paragraphs, but I would like for them to be displayed on the same line.

我正在使用Apace POI处理一些文档，我想添加一个由多个段落组成的页眉/页脚，但我希望它们显示在同一行。

This is my attempt so far:

这是我到目前为止的尝试：

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);

However, the end result so far is that I get a single right-aligned text, which consists of the two XWPFParagraphs, concatenated.

然而，到目前为止的最终结果是我得到一个右对齐的文本，它由两个连接起来的XWPFParagraph组成。

I have also checked some other examples here on Stack Overflow (there was one for a Header, but I didn't manage to get it to work).

我还在Stack Overflow上检查了一些其他示例（有一个用于Header，但我没有设法让它工作）。

A basic idea of what I want to achieve is this: http://imgur.com/jrwVO0F

Any ideas on what I am doing wrong?

关于我做错的任何想法？

Thank you,

Add Tabstops and use them

Here's my draft - printing my Name Left, Center and Right on a A4 Document. I have no clue whatsoever as to how those position elements are calculated though... Code to add tabstops is from Java Apache POI Tab Stop word document

这是我的草稿 - 在A4文档上打印我的名字左，中，右。我不知道如何计算这些位置元素...添加tabstops的代码来自Java Apache POI Tab Stop word文档

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);

            }
            Desktop.getDesktop().open(f);

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

    public static void setTabStop(XWPFParagraph oParagraph, STTabJc.Enum oSTTabJc, BigInteger oPos) {

        oTabStop.setVal(oSTTabJc);
        oTabStop.setPos(oPos);
    }
}

So, after some tinkering, I finally have a functioning version. Here's hoping it will prove useful to other users as well.

所以，经过一些修补，我终于有了一个功能正常的版本。这里希望它对其他用户也有用。

Creating footer object code

    // create footer components
    XWPFDocument document = new XWPFDocument();
    CTP footerCtp = CTP.Factory.newInstance();
    CTR footerCtr = footerCtp.addNewR();
    XWPFParagraph footerCopyrightParagraph = new XWPFParagraph(footerCtp, document);

    run.setText("My Website.com");
    run.addTab();
    run.setText("\u00A9" + " My Website - " + Calendar.getInstance().get(Calendar.YEAR));
    run.addTab();
    run.setText("Right Side Text");

    setTabStop(footerCtp, STTabJc.Enum.forString("right"), BigInteger.valueOf(9000));

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

SetTabStop method
