Prerequisites
Good knowledge of IS architectures and standard communication protocols. Good knowledge of the Java language. Knowledge of the Spring framework is a plus.
Practical details
Hands-on work
Implementation of a "red thread" case study to serve as a framework for all the practical work carried out.
Course schedule
1 The challenges of enterprise integration
- Corporate integration styles.
- Service-oriented versus event-oriented architecture.
- Messaging style.
- Introduction to EIP.
Hands-on work
Appropriation of the case study.
2 The Apache Camel framework
- Camel and EIP.
- Message anatomy.
- Route components (exchange, endpoints, processor, router, transformer), Pipe and Filter model.
- Route implementation in Java DSL and Spring DSL (XML).
- Work on message content using scripting languages (simple, XPath, SpEL, etc.).
- Endpoint components: file, mail, ActiveMQ, JMS, direct.
Hands-on work
Route design: transfer files to JMS queues, distribute information by e-mail.
3 Transforming message content
- EIP Message Translator: the different techniques (Processor, Beans, DSL, Expressions).
- EIP Content Enricher: enrich versus pollEnrich.
- XML transformation: XSLT, marshaling / unmarsharling.
- Predefined format transformation components (csv, xml, json, zip, etc.).
- Transformation using templates (Velocity, Freemarker).
- Design your own converters.
Hands-on work
Transform the content of messages carried by previously created routes.
4 Endpoint and gateway components
- Camel components.
- Communication in memory (Direct, SEDA, VM), via web services (CXF, CXFRS, Restlet), asynchronous (JMS).
- Database access : JDBC, JPA.
- Periodic activation of routes : Timer, Quartz.
- Using gateways: CamelProxy and @Consume and @Produce annotations.
Hands-on work
Integration of existing applications, proxification of web services (SOAP and REST), use of gateways.
5 Message routing
- Message filtering and broadcasting.
- Static routing: content-based router, recipientList.
- Dynamic routing: routingSlip, dynamicRouter.
- Load balancing and failover.
Hands-on work
Implement routing strategies and load balancing.
6 Activity tracking and error management
- Route activity monitoring: Log and Wiretap, JConsole.
- Recoverable and non-recoverable errors, associated strategies.
- Predefined error handling: DefaultErrorHandler, DeadLetterChannel, LoggingErrorHandler.
- Redelivery after error.
- Exception handling: onException().
Hands-on work
Add metrics, message logging, error handling.
