The document presents an overview of Spring Boot and Spring Integration, emphasizing their role in building production-ready applications and supporting enterprise integration patterns. It outlines the essential features of Spring Boot, including stand-alone applications and automatic configuration, while describing Spring Integration's capabilities for messaging and external system integration. The agenda includes creating a Spring Integration application for Bitcoin data, setting up an MQTT client, and provides guidance on tools and libraries required for the integration process.

2. Spring Boot
Takes an opinionated view of building production-ready Spring
applications. Spring Boot favors convention over configuration and is
designed to get you up and running as quickly as possible.
• Create stand-alone Spring applications
• Embed Tomcat or Jetty directly (no need to deploy WAR files)
• Opinionated 'starter' POMs
• Automatically configure Spring whenever possible
• Absolutely no code generation and no requirement for XML configuration

3. Spring Integration
Extends the Spring programming model to support the well-known Enterprise
Integration Patterns.
• Spring Integration enables lightweight messaging and supports integration with
external systems.
• Adapters provide a higher-level of abstraction over Spring's support for remoting,
messaging, and scheduling.
• ReST/HTTP
• SFTP/FTP
• RabbitMQ
• JMS
• TCP/UDP
• Spring Integration's primary goal is to provide a simple model for building enterprise
integration solutions while maintaining the separation of concerns that is essential
for producing maintainable, testable code.

4. Agenda
• Create a SI application
– that gathers bid data from various bitcoin banks and markets.
– Translate data
– Send data MQTT Client
• Create MQTT Client
– Create a basic application to receive MQTT messages
– Report to console what was received
– Count total messages received.

7. Lets setup our integration to write to a file.
• Setup the CoinBase http outbound gateway.
• Setup our Main application
4.0
• Setup the Transform
• Setup the BitStamp http outbound gateway
• Setup the MQTT outbound-channel-adapter
4.1

11. 4.1 MQTT Features
• Async Sends
• HA Omit the url and use the serverURIs from
theDefaultMqttPahoClientFactory
• Supports QoS for each subscription
• Programmatically subscribe and unsubscribe from topics at
runtime.

12. Security
• Does MQTT support security?
– MQTT supports Authentication
• Pass a user name and password with an MQTT packet as of
version 3.1
– Independently setup SSL
• But that can be heavy
– Application encrypts/decrypts the data
• Authorization?
• World Peace?

13. Now lets setup the MQTT Listener
• Setup build.gradle
• Setup Integation.xml
• Setup the Main
