Overview of this book

This book is intended for developers who are either already involved with enterprise integration or planning to venture into the domain. Basic knowledge of Java and Spring is expected. For newer users, this book can be used to understand an integration scenario, what the challenges are, and how Spring Integration can be used to solve it. Prior experience of Spring Integration is not expected as this book will walk you through all the code examples.

Integration

Now is the time for actual integration! Once the router has routed the message to the appropriate endpoints, it should be processed by them. For example, it can be persisted to a database, sent on a JMS channel, or sent as an e-mail. Depending on the payload type, the router will put the message on to one of the channels jdbcChannel, jmsChannel, or mailChannel. If it cannot understand the payload, it will route it to logChannel. Let's start with the endpoint attached to the channel jdbcChannel that is used for database integration.

Database integration

In this section, we will write code to add and query data from a database. Before we write adapters from Spring Integration, let's do the basic setup.

Prerequisites

As obvious as it can be, we need a database where we can dump the data. For simplicity, we will use the in-memory database. Let's also configure the ORM provider, transaction, and other aspects to be used with the database:

  • Declaration of the embedded database:
