Java 在Word中设置多行文本水印

1. 手动下载导入，解压下载后的jar包，将lib文件夹下的Spire.Doc.jar文件导入java程序；
2. 创建Maven程序时，在pom.xml中配置maven仓库路径并指定Free Spire.Doc for Java的依赖，如下：

<repositories>
        <repository>
            <id>com.e-iceblue</id>
            <url>http://repo.e-iceblue.cn/repository/maven-public/</url>
        </repository>
    </repositories>
<dependencies>
    <dependency>
        <groupId> e-iceblue </groupId>
        <artifactId>spire.doc.free</artifactId>
        <version>2.7.3</version>
    </dependency>
</dependencies>

                paragraph1 = header.addParagraph();
                for (int j = 0; j < 3; j++) {
                    //复制艺术字并设置多行多列位置
                    shape = (ShapeObject) shape.deepClone();
                    shape.setVerticalPosition(50 + 200 * i);
                    shape.setHorizontalPosition(20 + 160 * j);
