poi-tl怎样在word中添加图片并使图片居中

1.在pom.xml文件中导入poi-tl：

        <dependency>
            <groupId>com.deepoove</groupId>
            <artifactId>poi-tl</artifactId>
            <version>1.9.1</version>
        </dependency>

2.编写测试类：
 

package com.mischen.mapreduce.wordcount;

import com.deepoove.poi.xwpf.NiceXWPFDocument;
import org.apache.poi.util.Units;
import org.apache.poi.xwpf.usermodel.ParagraphAlignment;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.util.List;

        // 合并两个文档

        newDoc.close();
        out.close();*/

        XWPFDocument doc = new XWPFDocument(new FileInputStream("C:\\Users\\Administrator\\Desktop\\PMP\\new_doc.docx"));
        // 段落
        List<XWPFParagraph> paragraphs = doc.getParagraphs();
        InputStream stream = new FileInputStream("C:\\Users\\Administrator\\Pictures\\Saved Pictures\\稳定就业证明模板.png");
        int length=paragraphs.size();
        XWPFParagraph p1 = paragraphs.get(length-1);
        // 对齐方式,ParagraphAlignment.CENTER表示居中
        p1.setAlignment(ParagraphAlignment.CENTER);
        XWPFRun run = p1.createRun();
        run.addPicture(stream, XWPFDocument.PICTURE_TYPE_PNG, "Generated", Units.toEMU(256), Units.toEMU(256));
        FileOutputStream out = new FileOutputStream("C:\\Users\\Administrator\\Desktop\\PMP\\3.docx");
        doc.write(out);
        out.close();
        System.out.println("合并word成功！");
    }
}
