Message-Driven Architecture: Spring Integration promotes the use of messages as a means of communication between components in your application. Messages encapsulate data and can be sent and received by various endpoints.
Message Endpoints: Endpoints are the building blocks of Spring Integration applications. They represent the points where messages enter or exit the system. There are various types of endpoints, such as inbound adapters, outbound gateways, and transformers, each serving a specific purpose.
Channels: Channels act as conduits for messages, allowing them to flow from one endpoint to another. Channels can be configured to have different characteristics, such as point-to-point or publish-subscribe.
Message Adapters: Message adapters are used to connect external systems or resources to the Spring Integration application. They can be inbound (for receiving messages from external sources) or outbound (for sending messages to external destinations).
Message Transformers: Transformers are components that convert or manipulate messages as they pass through the integration flow. They are often used to adapt the message format to match the expectations of the receiving system.
Message Routers:Routers determine how messages should be distributed to different endpoints based on specific criteria. For example, you can route messages based on message content, headers, or other attributes.
Message Filters: Filters allow you to selectively accept or reject messages based on certain criteria. They are useful for implementing message validation and conditional processing.
Aggregators: Aggregators combine multiple related messages into a single message, typically used for gathering and processing data from multiple sources.
Splitter:The splitter component divides a single message into multiple messages, allowing you to process individual pieces of data separately.
Transaction Management: Spring Integration provides transactional support, allowing you to ensure that message processing is done within the scope of a transaction.
Error Handling: You can configure error handling strategies to deal with exceptions and errors that occur during message processing, including retry mechanisms and dead-letter channels.
Integration with Messaging Systems Spring Integration can seamlessly integrate with various messaging systems, including Apache Kafka, RabbitMQ, and JMS, making it suitable for building event-driven and message-driven architectures.
