Questions tagged [spring-integration]

Use this tag for questions about the Spring Integration project. It is not intended for general questions about integrating other Spring projects with other technologies.

Spring Integration provides an extension of the Spring programming model to support the well-known Enterprise Integration Patterns. Spring Integration enables lightweight messaging within Spring-based applications and supports integration with external systems via declarative adapters. Those adapters provide a higher-level of abstraction over Spring's support for remoting, messaging, and scheduling.

Use this tag for questions about the Spring Integration project. It is not intended for general questions about integrating other Spring projects with other technologies. For example "How do I integrate Spring MVC with Struts?" would not be an appropriate question for this tag. Whereas "How do I solve such-and-such issue with the Spring Integration xyz channel adapter?", or "How can I use Spring Integration to communicate with [some legacy system]?" would be appropriate.
