Discover the essentials of Apache Camel with Spring Boot in this masterclass, covering solution design, building components, and orchestrating data flows through theory and hands-on exercises.
Explore the course scope and prerequisites, including Java eight and Spring Boot basics. Demonstrate migrating a legacy batch file process to a messaging and rest based integration with Apache Camel.
We explore migrating a legacy file transfer application from batch processing to real-time data transfer, integrating source and destination system connections, API calls, and JPA-based mapping.
Build a base Apache Camel framework in Spring Boot, define routes with the Camel DSL, and bootstrap a boilerplate project using the Camel Spring Boot starter.
Build a simple Apache Camel timer route in Spring Boot, using a two-second timer and a log endpoint, with exchange body handling and constant values.
Demonstrates building a simple time-based Apache Camel route with Spring Boot, creating and asserting a message body in an exchange via a mock endpoint in a JUnit test.
Build a legacy file transfer workflow with Apache Camel and Spring Boot, converting a batch process into a poller that reads from a source folder and writes to a destination.
Extend camel springboot tests by adding unique test cases, and use mock endpoints and mock input data to control the flow from file poller to endpoints.
Develop self-contained JUnit tests for Apache Camel routes by mocking endpoints, including from endpoint, and using a producer template to send and verify message exchanges.
Learn how to define inline processes in Apache Camel, manipulating the exchange body from an endpoint to another via lambda functions to transform data, log results, and route to endpoints.
Learn how to use the splitter EIP to split a large file into rows, processing each row as a separate exchange, enabling streaming and memory-efficient processing.
Convert csv data to POJO using BeanIO mapping in a Spring Boot and Apache Camel context. Define mapping, add dependencies, and map records to Java objects.
Learn how to externalize processors as Java classes in Apache Camel with Spring Boot, transforming inbound exchanges into outbound entity objects and wiring external processing via a dedicated processor.
Recap section shows moving a legacy file through processors, splitting it to pass objects one at a time, marshaling data, converting to a destination Java object, and appending records.
Review section 4 exercise by adjusting the expected body and justifying changes, then run the test case to verify the solution in the Apache Camel with Springboot Masterclass.
Install Postman and MySQL to set up your system, validate and manage services, and work with databases for Apache Camel with Springboot Masterclass on the Mac OS platform.
Create a simple rest endpoint with Apache Camel in a Spring Boot app, migrating legacy processing to JSON posts, configuring routes, and testing the endpoint locally.
Learn to insert data records into a MySQL database using JPA and Hibernate within a Camel and Spring Boot setup, including defining a persistence unit and entity mapping.
Learn to read database records with a named query in an Apache Camel batch route that runs every 10 seconds and writes results to the log.
Split the incoming rules on the body attribute, transform them into two streams, and route them for processing while noting duplicates caused by repeatedly retrieving rules.
Delete records from database using native queries and dynamic routing in Camel with Spring Boot. Identify processed records with headers and delete them after they are written to the output.
Install Active MQ, download binaries, extract, and start the broker on your system. Access the web console, log in, and create a simple queue named address queue for testing.
Publish to ActiveMQ with the native Spring Boot component, configure broker and queue, and send serialized name address objects to the name address queue using the only pattern.
Subscribe to ActiveMQ messages by configuring the endpoint and queue, log received messages, and troubleshoot serialization trust issues through application properties.
Implement a rest endpoint to an ActiveMQ pub-sub workflow using Apache Camel with Spring Boot; read database entries, transform them via a processor, and write to a file.
Explore how to manage and reuse camel routes with Spring Boot, including multicast, direct routing, and active mq integration, to control propagation, database persistence, and id generation.
Examine the flow of a camel exchange by contrasting direct and seda endpoints and using wiretap to forward copies to a blocking queue for asynchronous processing, with Active MQ and database endpoints.
Enable tracing in Apache Camel to extend logging and reveal the exact sequence of exchange flow from a post call through queues to endpoints.
Explore how to use onException in Apache Camel to gracefully handle active MQ failures, generate alerts, and copy the original message for later processing across different messaging buses.
Override the default REST response by adjusting the request body and transforming the exchange to manage rest contracts, via post calls to ActiveMQ and a 200 OK.
Learn to use headers, choice and predicates with the simple language to route messages in Camel, and replace processors with beans for cleaner, modular logic.
Explore how Apache Camel components, data formats, and languages integrate with Spring Boot to design robust enterprise integration patterns, including routing, wiretap, and content-based routing.
Explore using DrawIO with Camel stencils to diagram Camel integrations. Create diagrammatic representation of messaging systems and messaging channels, and apply dynamic routing to visualize how your Camel integrations function.
Celebrate your completion of the course, reflect on covered topics, and empower you to use Apache Camel in enterprise integrations with a more structured approach in Spring.
Apache camel is genuinely an excellent technology within the integration domain, and by the end of this course, I genuinely believe you will be amazed at everything Apache Camel has to offer
Apache Camel is an open-source enterprise integration patterns platform built on the book of the same name by Gregor Hohpe and Bobby Woolf.
It has been around for more than a decade now, with active development still in the works.
This course is by no means attempting to provide a full-scope coverage of what Apache Camel has to offer
But we cover a lot of ground here. By the end of this course, you would have looked at all significant aspects of Enterprise Application development like design, legacy-system migration, exception handling, logging, database management, etc.
This course is designed as a hands-on exercise where the expectation is for you to build along to understand property-based behaviour changes with Camel better.
We will be starting by building a legacy file-based data transfer application and then migrating this to a REST-based API to collect data. Distribution of this data would then be done using messaging buses like ActiveMQ.
The course is structured so that almost all lectures start with theoretical concepts followed by hands-on development.
A couple of mid-section exercises will firm your understanding of the concepts.
