安装

本文介绍阿里云Java SDK推荐的Maven安装方式。具体包含2个步骤，首先需要在pom.xml配置文件中添加阿里云Java SDK的Maven仓库，然后再添加智能视觉的依赖。

  1. 添加maven仓库。

    1.  <repositories>
    2.     <repository>
    3.         <id>sonatype-nexus-staging</id>
    4.         <name>Sonatype Nexus Staging</name>
    5.         <url>https://oss.sonatype.org/service/local/staging/deploy/maven2/</url>
    6.         <releases>
    7.             <enabled>true</enabled>
    8.         </releases>
    9.         <snapshots>
    10.             <enabled>true</enabled>
    11.         </snapshots>
    12.     </repository>
    13. </repositories>

  2. 添加依赖阿里云Java SDK核心库以及智能视觉Java SDK的详细版本：

以3.5.0版本SDK的核心库和1.1.0版本的智能视觉SDK为例：

  1.     <dependency>
  2.         <groupId>com.aliyun</groupId>
  3.         <artifactId>aliyun-java-sdk-core</artifactId>
  4.         <version>3.5.0</version>
  5.     </dependency>
  6.     <dependency>
  7.         <groupId>com.aliyun</groupId>
  8.         <artifactId>aliyun-java-sdk-ivision</artifactId>
  9.         <version>1.1.0</version>
  10.     </dependency>

另外有一个可选的json库依赖。在智能视觉的API中，很多参数都是json定义，java的json库有很多，可以选择熟悉的库，以1.2.51版本的 fastjson 为例：

  1.     <dependency>
  2.         <groupId>com.alibaba</groupId>
  3.         <artifactId>fastjson</artifactId>
  4.         <version>1.2.51</version>
  5.     </dependency>

pom.xml完整示例：

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  3.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  5.     <groupId>com.aliyun.ivision</groupId>
  6.     <artifactId>demo</artifactId>
  7.     <version>0.0.1-SNAPSHOT</version>
  8.     <repositories>
  9.         <repository>
  10.             <id>sonatype-nexus-staging</id>
  11.             <name>Sonatype Nexus Staging</name>
  12.             <url>https://oss.sonatype.org/service/local/staging/deploy/maven2/</url>
  13.             <releases>

  16.             <snapshots>

  18.             </snapshots>
  19.         </repository>
  20.     </repositories>
  21.     <dependencies>
  22.         <dependency>
