public class JpaOutboundGateway extends AbstractReplyProducingMessageHandler
The Jpa Outbound Gateway will allow you to make outbound operations to either:
  • submit (insert, delete) data to a database using JPA
  • retrieve (select) data from a database
Depending on the selected OutboundGatewayType, the outbound gateway will use either the JpaExecutor's poll method or its executeOutboundJpaOperation method.

In order to initialize the adapter, you must provide a JpaExecutor as constructor.
