本文介绍使用Spire.Cloud.SDK for Java 提供的BackgroundApi接口来操作Word文档背景的方法，可设置背景，包括设置颜色背景setBackgroundColor()、图片背景setBackgroundImage()，删除背景deleteBackground()和获取背景颜色getBackgroundColor()等。可参照以下步骤来操作：
步骤1****：导入jar****文件
创建Maven****项目程序，通过maven仓库下载导入。以IDEA为例，新建Maven项目，在pom.xml文件中配置maven仓库路径，并指定spire.cloud.sdk的依赖，如下：
<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> com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.8.1</version>
</dependency>
<dependency>
<groupId> com.squareup.okhttp</groupId>
<artifactId>logging-interceptor</artifactId>
<version>2.7.5</version>
</dependency>
<dependency>
<groupId> com.squareup.okhttp </groupId>
<artifactId>okhttp</artifactId>
<version>2.7.5</version>
</dependency>
<dependency>
<groupId> com.squareup.okio </groupId>
<artifactId>okio</artifactId>
<version>1.6.0</version>
</dependency>
<dependency>
<groupId> io.gsonfire</groupId>
<artifactId>gson-fire</artifactId>
<version>1.8.0</version>
</dependency>
<dependency>
<groupId>io.swagger</groupId>
<artifactId>swagger-annotations</artifactId>
<version>1.5.18</version>
</dependency>
<dependency>
<groupId> org.threeten </groupId>
<artifactId>threetenbp</artifactId>
<version>1.3.5</version>
</dependency>
</dependencies>
完成配置后，点击“Import Changes” 即可导入所有需要的jar文件。如果使用的是****Eclipse****，可参考这里的导入方法。
导入结果：
步骤2****：登录冰蓝云账号，创建文件夹，上传用于测试的源文档
步骤3****：创建应用程序，获取App ID****及App Key
完成以上步骤后，接下来可参考Java示例代码进行Word文档操作
示例1****——设置Word****背景颜色
import spire.cloud.word.sdk.client.*;
import spire.cloud.word.sdk.client.api.*;
import spire.cloud.word.sdk.client.model.*;
public class BackgroundColor {
//配置App账号信息
static String appId = "App ID";
static String appKey = "App Key";
static String baseUrl = "https://api.e-iceblue.cn";
static Configuration wordConfiguration = new Configuration(appId, appKey, baseUrl);
static BackgroundApi backgroundApi = new BackgroundApi(wordConfiguration);
public static void main(String[] args) throws ApiException{
String name = "Test.docx";//Word源文档
Color color = new Color(245,245,220);//指定背景颜色
String password = null;//源文档密码
String folder = "input";//源文档所在的云端文件夹
String destFilePath = "output/setBackgroundColor.docx";//结果文档路径
String storage = null;
//调用方法设置背景颜色
backgroundApi.setBackgroundColor(name, color, destFilePath, folder, storage, password);
}
}
背景色设置效果：
示例2****——设置Word****图片背景
可将云端图片或者本地路径图片设置为背景。
import spire.cloud.word.sdk.client.ApiException;
import spire.cloud.word.sdk.client.Configuration;
import spire.cloud.word.sdk.client.api.BackgroundApi;
import java.io.File;
public class ImageBackground {
//配置App账号信息
static String appId = "App ID";
static String appKey = "App Key";
static String baseUrl = "https://api.e-iceblue.cn";
static Configuration wordConfiguration = new Configuration(appId, appKey, baseUrl);
static BackgroundApi backgroundApi = new BackgroundApi(wordConfiguration);
public static void main(String[] args) throws ApiException {
String name = "Test.docx";//Word源文档
String imagePath = "input/tp.png";//背景图片路径（云端input文件夹下）
//File inputImage = new File("inputFile/Background.png");//本地图片路径
String password = null;//源文档密码
String folder = "input";//源文档所在云端文件夹
String destFilePath = "output/setBackgroundImage.docx";//结果文档路径（云端output文件夹下）
String storage = null;
//调用方法将云端图片设置为背景图片
backgroundApi.setBackgroundImage(name, imagePath, destFilePath, folder, storage, password);
//将本地图片设置为背景图片
//backgroundApi.setBackgroundImageInRequest(name, inputImage, destFilePath, folder, storage, password);
}
}
图片背景设置效果：
示例3****——删除Word****背景
import spire.cloud.word.sdk.client.ApiException;
import spire.cloud.word.sdk.client.Configuration;
import spire.cloud.word.sdk.client.api.BackgroundApi;
public class DeleteBackground {
//配置App账号信息
static String appId = "App ID";
static String appKey = "App Key";
static String baseUrl = "https://api.e-iceblue.cn";
static Configuration wordConfiguration = new Configuration(appId, appKey, baseUrl);
static BackgroundApi backgroundApi = new BackgroundApi(wordConfiguration);
public static void main(String[] args) throws ApiException {
String name = "setBackgroundColor.docx";//Word源文档
String password = null;//源文档密码
String folder = "output";//源文档所在云端文件夹
String destFilePath = "output/deleteBackground.docx";//结果文档路径
String storage = null;
//调用方法删除背景
backgroundApi.deleteBackground(name, destFilePath, password, folder, storage);
}
}
背景删除效果：
示例4****——获取Word****背景色
import spire.cloud.word.sdk.client.ApiException;
import spire.cloud.word.sdk.client.Configuration;
import spire.cloud.word.sdk.client.api.BackgroundApi;
import spire.cloud.word.sdk.client.model.Color;
public class GetBackgroundColor {
//配置App账号信息
static String appId = "App ID";
static String appKey = "App Key";
static String baseUrl = "https://api.e-iceblue.cn";
static Configuration wordConfiguration = new Configuration(appId, appKey, baseUrl);
static BackgroundApi backgroundApi = new BackgroundApi(wordConfiguration);
public static void main(String[] args) throws ApiException {
String name = "setBackgroundColor.docx";//Word源文档
String password = null;//源文档密码
String folder = "output";//源文档所在云端文件夹
String storage = null;
//获取背景颜色
Color response = backgroundApi.getBackgroundColor(name, password, folder, storage);
System.out.println(response);
}
}
背景色读取效果：
（完）
