本文介绍了如何使用阿里云IVPD服务的Java SDK，具体包括SDK的获取和安装方法以及SDK代码示例。

获取地址

您需要引入两个SDK，包括aliyun-java-sdk-core（阿里云核心SDK）和aliyun-java-sdk-ivpd（智能视觉生产SDK）。每个SDK都提供了Maven Repository、Central Repository、GitHub的获取方式，您可以选择合适的方式获取SDK。

• aliyun-java-sdk-core：从以下方式中单击选择一种方式。
  • mvnrepository
  • GitHub
• aliyun-java-sdk-ivpd: 从以下方式中单击选择一种方式。
  • mvnrepository
  • GitHub

安装说明

方法1：使用Maven（推荐）

如果您使用Maven管理Java项目，可以通过在pom.xml文件中添加Maven依赖：

<dependency>
    <groupId>com.aliyun</groupId>
    <artifactId>aliyun-java-sdk-ivpd</artifactId>
    <version>${aliyun.ivpd.version}</version>
</dependency>

说明 version的值以SDK获取地址中的最新版本为准。

方法2：在集成开发环境（IDE）中导入jar文件

• Eclipse安装
  • 将下载的aliyun-java-sdk-xxx.jar文件复制到您的项目文件夹中。
  • 在Eclipse中打开您的项目，右键单击该项目，单击Properties。
  • 在弹出的对话框中，单击Java Build Path > Libraries > Add JARs添加下载的JAR文件。
  • 单击Apply and Close。
• IntelliJ 安装
  • 将下载的aliyun-java-sdk-xxx.jar文件复制到您的项目文件夹中。
  • 在IntelliJ中打开您的项目，在菜单栏中单击File > Project > Structure。
  • 单击Apply，然后单击OK。
