IoT Platform:Initialize the SDKs

Prepare the development environment

In this example, the development environment consists of the following components:

• Operating system: Windows 10
• Java Development Kit (JDK): JDK 8
• Integrated development environment (IDE): IntelliJ IDEA Community Edition

Procedure

1. Download and decompress the SDK package iotx-api-demo.
   This package contains the device SDK for Java and IoT Platform SDK for Java.
2. Open IntelliJ IDEA and import the decompressed sample project iotx-api-demo.
3. Add the following Maven dependencies to the pom.xml file to import the IoT Platform SDK and Link SDK:

   <!-- https://mvnrepository.com/artifact/com.aliyun/aliyun-java-sdk-iot -->
   <dependency>
       <groupId>com.aliyun</groupId>
       <artifactId>aliyun-java-sdk-iot</artifactId>
       <version>7.41.0</version>
   </dependency>
   <dependency>
       <groupId>com.aliyun</groupId>
       <artifactId>aliyun-java-sdk-core</artifactId>
       <version>4.5.6</version>
   </dependency>
   <dependency>
     <groupId>com.aliyun.alink.linksdk</groupId>
     <artifactId>iot-linkkit-java</artifactId>
     <version>1.2.0.1</version>
     <scope>compile</scope>
   </dependency>

4. In the java/src/main/resources/ directory, open the config file and specify the required information for initialization.

   user.accessKeyID = <your accessKey ID>
   user.accessKeySecret = <your accessKey Secret>
   iot.regionId = <regionId>
   iot.productCode = Iot
   iot.domain = iot.<regionId>.aliyuncs.com
   iot.version = 2018-01-20

   Parameter	Description
   accessKeyID	The AccessKey ID and AccessKey secret of your Alibaba Cloud account. Log on to the IoT Platform console, move the pointer over the profile picture, and then click AccessKey Management to obtain the AccessKey ID and AccessKey secret.
   accessKeySecret
   regionId	The ID of the region where your device resides. For information about the format of region IDs, see Regions.
   productCode	The code of the cloud service. Set the value to Iot for IoT Platform.
