云端Office处理工具Spire.Cloud.Word Java版基础教程：添加文本水印和图片水印

Spire.Cloud.Word API给开发者提供了一个WatermarksApi类，用于添加和操作水印。你可以Spire.Cloud Web SDK。

1、请通过 Maven仓库安装Spire.Cloud.Word jar包及SDK。其次，需要在冰蓝云官 (https://cloud.e-iceblue.cn) 注册账 ，创建我的应用程序，获得 APP ID 及 App Key。

2、点击导航栏“文档管理”，将Word文档和水印图片上传至“我的文档”。

3、创建一个Maven应用程序，在pom.xml文件中添加Spire.Cloud.Word的Maven依赖。

<repositories>    <repository>        <id>com.e-iceblue</id>        <name>cloud</name>        <url>http://repo.e-iceblue.cn/repository/maven-public/</url>    </repository></repositories><dependencies>    <dependency>            <groupId> cloud </groupId>            <artifactId>spire.cloud.sdk</artifactId>            <version>3.5.0</version>        </dependency>    <dependency>        <groupId>io.swagger</groupId>        <artifactId>swagger-annotations</artifactId>        <version>1.5.18</version>    </dependency>    <dependency>        <groupId>com.squareup.okhttp</groupId>        <artifactId>okhttp</artifactId>        <version>2.7.5</version>    </dependency>    <dependency>        <groupId>com.squareup.okhttp</groupId>        <artifactId>logging-interceptor</artifactId>        <version>2.7.5</version>    </dependency>    <dependency>        <groupId> com.squareup.okio </groupId>        <artifactId>okio</artifactId>        <version>1.6.0</version>    </dependency>    <dependency>        <groupId>com.google.code.gson</groupId>        <artifactId>gson</artifactId>        <version>2.8.1</version>    </dependency>    <dependency>        <groupId>io.gsonfire</groupId>        <artifactId>gson-fire</artifactId>        <version>1.8.0</version>    </dependency>    <dependency>        <groupId>org.threeten</groupId>        <artifactId>threetenbp</artifactId>        <version>1.3.5</version>    </dependency></dependencies>

4、新建Java class，调用Spire.Cloud.Word API给Word文档添加水印。

添加文本水印示例代码

import spire.cloud.word.sdk.client.ApiException;import spire.cloud.word.sdk.client.Configuration;import spire.cloud.word.sdk.client.api.WatermarksApi;import spire.cloud.word.sdk.client.model.Color;import spire.cloud.word.sdk.client.model.Font;import spire.cloud.word.sdk.client.model.TextWatermark;public class TextWatermark {    private static String appId = "App ID";    private static String appKey = "App Key";    public static void main(String[] args) throws ApiException {        //配置App ID和App Key        Configuration wordConfiguration = new Configuration(appId, appKey);        //创建WatermarksApi实例        WatermarksApi watermarksApi = new WatermarksApi(wordConfiguration);        //原文档        String name = "template.docx";        //存放原文档的文件夹，没有则为null        String folder = null;        //使用冰蓝云配置的2G空间存贮文档，可设置为null        String storage = null;        //文档密码，没有则为null        String password = null;        //创建TextWatermark实例        TextWatermark txtWatermark = new TextWatermark("内部使用");        //设置水印排版方式        txtWatermark.setLayout(TextWatermark.LayoutEnum.DIAGONAL);        Color color = new Color(255, 0, 0);        Font font = new Font("宋体", 80f, color);        //设置水印字体        txtWatermark.setFont(font);        //添加文本水印到文档并保存到指定路径        String destFilePath = "output/setTextWatermark.docx";        watermarksApi.setTextWatermark(name, txtWatermark, destFilePath, folder, storage, password);    }}

添加图片水印示例代码

import spire.cloud.word.sdk.client.ApiException;import spire.cloud.word.sdk.client.Configuration;import spire.cloud.word.sdk.client.api.WatermarksApi;public class ImageWatermark {    private static String appId = "App ID";    private static String appKey = "App Key";    public static void main(String[] args) throws ApiException {        //配置App ID和App Key        Configuration wordConfiguration = new Configuration(appId, appKey);        //创建WatermarksApi实例        WatermarksApi watermarksApi = new WatermarksApi(wordConfiguration);        //原文档        String fileName = "template.docx";        //水印图片        String imagePath = "background.png";        //存放原文档的文件夹，没有则为null        String folder = null;        //使用冰蓝云配置的2G空间存贮文档，可设置为null        String storage = null;        //水印图片缩放比例        Integer scaling = 120;        //是否冲蚀        Boolean washout = true;        //文档密码，没有则为null        String password = null;        //添加图片水印到文档并保存到指定路径        String destFilePath = "output/setImageWatermark.docx";        watermarksApi.setImageWatermark(fileName, imagePath, destFilePath, folder, storage, scaling, washout, password);    }}
