Spring Message Outbox

Spring Message Outbox is a library that implements the outbox pattern for Spring Boot. This library is currently in an ALPHA state and in heavy development. It is not advisable to use this library in production. Contributions or bug reports are welcome.

Usage

• Add outbox-core as a dependency to your project.
• Add a storage module as a dependency and import its configuration class into a Spring configuration class using @Import
• Add a publisher module as a dependency and import its configuration class into a Spring configuration class using @Import
• Autowire the Outbox class and publish messages using outbox.publish().

Core Module

• Core Module - Implements the core workflow of the outbox pattern.

Storage Modules

Storage modules implement the OutboxMessageRepository interface and provide persistence for the outbox messages before they are published.

• outbox-storage-postgres - uses Postgresql to store outbox messages

Publisher Modules

Publisher modules implement the OutboxMessagePublisher interface and provide a mechanism to publish outbox messages on a specific message channel.

• outbox-publisher-logging - Logs messages to the log instead of publishing. Useful for testing.
• outbox-publisher-rabbitmq - Publishes messages to a RabbitMq exchange.
