Spring Integration allows for building integration flows with Java code instead of XML configuration. It provides inbound and outbound adapters to connect to resources like databases, web services, and message queues. The integration flows define the business logic and transformations to process messages from the inbound to outbound adapters using common EAI patterns like routers, filters, and transformers.
