Java

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。

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：

  1.  <dependency>
  2.     <groupId>com.aliyun</groupId>
  3.     <artifactId>aliyun-java-sdk-ivpd</artifactId>
  4.     <version>1.0.2</version>
  5. </dependency>
  6. <dependency>
  7.     <groupId>com.aliyun</groupId>
  8.     <artifactId>aliyun-java-sdk-core</artifactId>
  9.     <version>4.4.9</version>
  10. </dependency>
  11. <dependency>
  12.     <groupId>com.alibaba</groupId>
  13.     <artifactId>fastjson</artifactId>
  14.     <version>1.2.60</version>
  15. </dependency>
  16. <dependency>
  17.     <groupId>org.apache.httpcomponents</groupId>
  18.     <artifactId>httpclient</artifactId>
  19.     <version>4.5.3</version>
  20. </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。
