通过aspose-words往word中添加水印

1、添加依赖

<dependency>
			<groupId>com.aspose</groupId>
			<artifactId>aspose-words</artifactId>
			<version>15.8.0</version>
			<scope>system</scope>
			<systemPath>${project.basedir}/lib/aspose-words-15.8.0-jdk16.jar</systemPath>
		</dependency>

在src/main/resources/下添加证书文件license.xml

通过poi往excel中添加图片

1、添加maven依赖

XML 复制代码 
<dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi</artifactId>
            <version>5.3.0</version>
        </dependency>

        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>5.3.0</version>
        </dependency>

        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-contrib</artifactId>
            <version>3.6</version>
        </dependency>

        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml-schemas</artifactId>
            <version>4.1.2</version>
        </dependency>

2、添加图片的代码

java 复制代码 
import org.apache.poi.ss.usermodel.ClientAnchor;
import org.apache.poi.ss.usermodel.Drawing;
import org.apache.poi.ss.usermodel.FillPatternType;
import org.apache.poi.ss.usermodel.Font;
import org.apache.poi.ss.usermodel.HorizontalAlignment;
import org.apache.poi.ss.usermodel.Picture;
import org.apache.poi.util.IOUtils;
import org.apache.poi.util.Units;

Workbook wb
Sheet sheet
FileInputStream img = new FileInputStream("logo.png");
int pictureIndex = wb.addPicture(IOUtils.toByteArray(img), Workbook.PICTURE_TYPE_PNG);


Drawing drawing = sheet.createDrawingPatriarch();
// 这几个参数的含义：图片距离左上角x轴方向距离，距离左上角y轴方向距离，距离右下角x轴方向距离，距离右下角y轴方向距离，左上角所在行数，左上角所在列数，右下角所在行数，右下角所在列数
ClientAnchor anchor = drawing.createAnchor(45 * Units.EMU_PER_POINT, 10 * Units.EMU_PER_POINT, -15 * Units.EMU_PER_POINT, -10 * Units.EMU_PER_POINT, 4, 1, 6, 2);
			
Picture picture = drawing.createPicture(anchor, pictureIndex);
img.close();
