Any application in today's context is incomplete if it does not provide support for social messaging. Spring Integration provides in-built support for many social interfaces such as e-mails, Twitter feeds, and so on. Let's discuss the implementation of Twitter in this section. Prior to Version 2.1, Spring Integration was dependent on the Twitter4J API for Twitter support, but now it leverages Spring's social module for Twitter integration. Spring Integration provides an interface for receiving and sending tweets as well as searching and publishing the search results in messages. Twitter uses oauth for authentication purposes. An app must be registered before we start Twitter development on it.
