Outbound JDBC Adapters

The outbound JDBC adapters are used to execute SQL queries in the database. The SQL query is constructed with the appropriate value fetched from the incoming Message. So, the outbound adapter listens on a message channel, picks up a message, extracts the relevant values, constructs the query and executes the query on the Database.

Let’s look at an example where every Trade message appearing on a trade-persistence-channel should be persisted. Under normal circumstances, we could have written a consumer that picks up each message and then uses persistence mechanics to store the message in the database. However, Spring Integration’s outbound adapter saves you from writing this extra code.
