The AWS IoT Device SDK for Java enables Java developers to access the AWS IoT Platform through MQTT or MQTT over the WebSocket protocol. The SDK is built with AWS IoT device shadow support, providing access to thing shadows (sometimes referred to as device shadows) using shadow methods, including GET, UPDATE, and DELETE. It also supports a simplified shadow access model, which allows developers to exchange data with their shadows by just using getter and setter methods without having to serialize or deserialize any JSON documents. A new AWS IoT Device SDK is now available. It is a complete rework, built to improve reliability, performance, and security. We invite your feedback! The SDK is built on top of the Paho MQTT Java client library. Developers can choose from two types of connections to connect to the AWS IoT service.
Features
- MQTT (over TLS 1.2) with X.509 certificate-based mutual authentication
- MQTT over WebSocket with AWS Signature Version 4 authentication
- For MQTT over TLS (port 8883), a valid certificate and private key are required for authentication
- For MQTT over WebSocket (port 443), a valid AWS Identity and Access Management (IAM) access key ID and secret access key pair is required for authentication
- The SDK implements the protocol for applications to retrieve, update, and delete shadow documents
- The SDK is built on top of the Paho MQTT Java client library
