2.项目目录

 3.项目yaml配置

server:
  port: 8085
spring:
  resources:
    static-locations: classpath:/iot/dist

4.阿里云IOT客户端配置bean

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.profile.IClientProfile;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

@Configuration
public class AliIOTConfig {

    private static final String ACCESSKEY = "xxx";
    private static final String ACCESSSECRET = "yyy";

    /**
     * 默认AliIOTConfig
     * @return
     */
    @Primary
    @Bean
    public DefaultAcsClient restTemplate() throws ClientException {
        DefaultProfile.addEndpoint("cn-shanghai", "cn-shanghai", "Iot", "iot.cn-shanghai.aliyuncs.com");
        IClientProfile profile = DefaultProfile.getProfile("cn-shanghai", ACCESSKEY, ACCESSSECRET);
        DefaultAcsClient client = new DefaultAcsClient(profile); //初始化SDK客户端。

        return client;
    }

}

5.Test模拟发送数据给设备

import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.iot.model.v20180120.PubRequest;
import com.aliyuncs.iot.model.v20180120.PubResponse;
import net.sf.json.JSONObject;
import org.apache.commons.codec.DecoderException;
import org.apache.commons.codec.binary.Base64;
import org.apache.commons.codec.binary.Hex;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import java.io.IOException;
    

@RunWith(SpringRunner.class)
@SpringBootTest
public class IotdemoApplicationTests {

    @Autowired
    private DefaultAcsClient defaultAcsClient;

    @Test
    void send() throws DecoderException {

        JSONObject data = new JSONObject();

        data.put("gpio_out_a",255);
        data.put("gpio_out_b",255);

        PubRequest request = new PubRequest();
        request.setProductKey("XXXXXXX");
        request.setMessageContent(Base64.encodeBase64String((data.toString()).getBytes()));
        request.setTopicFullName("/a1fkKLo7NeH/YYYYYYYYYYYY/user/uart");
        request.setQos(0); //目前支持QoS0和QoS1。
        try {
            PubResponse response = defaultAcsClient.getAcsResponse(request);
            System.out.println(response);
            //System.out.println(response.getSuccess());
            //System.out.println(response.getErrorMessage());
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            e.printStackTrace();
        }

    }
}
