awsIot for Java 创建Iot设备客户端服务

使用aws-iot-device服务，需要导入

    com.amazonaws
    aws-iot-device-sdk-java
    1.2.0


    com.amazonaws
    aws-iot-device-sdk-java-samples
    1.2.0

代码开始：

private static String ACCESS_KEY = "你的亚马逊账户访问密钥ID";
private static String SECRET_ACCESS_KEY = "你的亚马逊账户访问密钥内容";

private static String CLIENT_ENDPOINT = "xxxxx.iot.us-east-1.amazonaws.com";
private static String CLIENT_ID = "你的事物名称";
