Spire.Cloud.SDK for Java提供了PdfAttachmentsApi接口添加附件addAttachment()、下载附件downloadAttachment()、获取附件信息getAttachmentsInfo()，本文将通过Java代码示例介绍具体实现方法。详细内容参考以下步骤：

**一、导入jar文件。**（有2种方式）

**（推荐）方式1. **创建Maven**项目程序，通过**[maven][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**][Link 1]**的导入方法。**

导入结果：

**方式2****：**手动[下载][Link 2]jar包，然后解压文件，手动导入jar，同时还需另行手动导入其他几个jar文件。

**二、登录冰蓝云账号，创建文件夹，上传文档。**

**三、创建应用程序，获取App ID****及App Key****。**

**四、Java****代码示例**

【示例1】添加附件

import spire.cloud.pdf.sdk.ApiException;
    import spire.cloud.pdf.sdk.Configuration;
    import spire.cloud.pdf.sdk.api.PdfAttachmentsApi;
    
    import java.io.File;
    
    public class AddAttachment {
        static String appId = "App ID";
        static String appKey = "App Key";
        static String baseUrl= "https://api.e-iceblue.cn";
        static Configuration configuration = new Configuration(appId, appKey, baseUrl);
        static PdfAttachmentsApi pdfAttachmentsApi = new PdfAttachmentsApi(configuration);
    
        public static void main(String[] args) throws ApiException {
            String name = "sample.pdf";//用于测试的PDF源文档
            String outPath = "output/AddAttachment.pdf";//结果文档路径（结果文档保存在云端output文件夹下）
            File file = new File("test.docx");//加载附件文档
            String attachmentFileName = "AddAttachment.docx";//设置附件文档名称
            String attachmentDescription = "A Nice File";//附件描述
            String folder = "input";//源文档所在文件夹
            String storage = null;//冰蓝云提供的2G免费云存储空间
            String password = null;//源文档密码
    
            //调用方法添加附件
            pdfAttachmentsApi.addAttachment(name, outPath, file, attachmentFileName, attachmentDescription, folder, storage, password);
        }
    }

附件添加结果：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0VpY2VibHVl_size_16_color_FFFFFF_t_70 3][]

【示例2】下载附件文档（以上文中生成的PDF文档为例，读取添加的Word附件）

import spire.cloud.pdf.sdk.ApiException;
    import spire.cloud.pdf.sdk.Configuration;
    import spire.cloud.pdf.sdk.api.PdfAttachmentsApi;
    
    import java.io.File;
    
    
    public class DownloadAttachment {
        //配置账号信息
        static String appId = "App ID";
        static String appKey = "App Key";
        static String baseUrl= "https://api.e-iceblue.cn";
        static Configuration configuration = new Configuration(appId, appKey, baseUrl);
        static PdfAttachmentsApi pdfAttachmentsApi = new PdfAttachmentsApi(configuration);
    
        public static void main(String[] args) throws ApiException {
            String name = "AddAttachment.pdf";//包含附件的PDF源文档
            Integer orderNumber = 1;
            String folder = "output";//源文档所在云端文件夹
            String storage = null;//冰蓝云提供的2G免费云存储空间
            String password = null;//源文档密码
    
            //调用方法下载PDF文档中的附件文档
            File response = pdfAttachmentsApi.downloadAttachment(name, orderNumber, folder, storage, password);
            System.out.println(response);
        }
    }

下载结果如下，可在路径中查看下载的附件文档：

【示例3】获取附件信息

import spire.cloud.pdf.sdk.ApiException;
    import spire.cloud.pdf.sdk.Configuration;
    import spire.cloud.pdf.sdk.api.PdfAttachmentsApi;
    import spire.cloud.pdf.sdk.model.Attachments;
    
    public class GetAttachmentInfo {
        //配置账号信息
        static String appId = "App ID";
        static String appKey = "App Key";
        static String baseUrl= "https://api.e-iceblue.cn";
        static Configuration configuration = new Configuration(appId, appKey, baseUrl);
        static PdfAttachmentsApi pdfAttachmentsApi = new PdfAttachmentsApi(configuration);
    
        public static void main(String[] args) throws ApiException {
            String name = "AddAttachment.pdf";//包含附件的PDF源文档
            String folder = "output";//源文档所在文件夹
            String storage = null;//冰蓝云提供的2G云存储空间
            String password = null;//源文档密码
    
            //调用方法获取附件信息
            Attachments response = pdfAttachmentsApi.getAttachmentsInfo(name, folder, storage, password);
            System.out.println(response);
        }
    }

附件信息读取结果：
