Spring Integration
What Spring Integration is
Spring Integration is an open-source framework for messaging within Spring applications and connecting them with external systems. It links reusable POJO components through a messaging model to form modular integration flows. The framework implements most Enterprise Integration Patterns, including channels, aggregators, filters, transformers, and a control bus. Channel adapters handle one-way sending or receiving, while gateways support request/reply in either direction. Listed connections include HTTP, FTP/SFTP, STOMP, SOAP and REST web services, TCP/UDP, JMS, RabbitMQ, and email. The project documents Spring Boot auto-configuration and a Java DSL for defining flows, and Spring Initializr can bootstrap a project with the relevant dependencies. Spring Integration is a self-hosted Java/Spring application dependency under the Apache 2.0 license, with an open-source plan listed at 0.00 USD. Spring Cloud Stream builds on it for message-driven microservices. JMX support exposes components as MBeans for reading attributes, invoking operations, and handling notifications. Tanzu Spring Enterprise offers paid support, including production troubleshooting and bug-fix support.
Who it suits
Spring Integration suits developers building integration flows in Java and Spring applications, especially where messaging with external systems is needed. Teams seeking production support can consider the separately described Tanzu Spring Enterprise support.
What it does well
- Open-source framework under the Apache 2.0 license.
- Implements most Enterprise Integration Patterns.
- Supports one-way messaging and request/reply.
- Documents Spring Boot auto-configuration and a Java DSL.
What to know first
- Designed as a dependency for Java/Spring applications.
- Self-hosted deployment is listed.
- Paid enterprise support is separate from the open-source plan.
Limits
