Spring Book – Chapter 20 – Spring Integration

Messaging (JMS)

Spring Integration provides Channel Adapters for receiving and sending JMS messages. There are actually two JMS-based inbound Channel Adapters as follows:

  • Uses Spring’s JmsTemplate to receive based on a polling period
  • Relies on Spring’s Message Listener Container and is considered “message-driven” approach

In addition, Spring Integration has an outbound Channel Adapter that uses the JmsTemplate to convert and send a JMS Message on demand.

The JMS Channel Adapters are intended for unidirectional Messaging (send-only or receive-only), Spring Integration also provides inbound and outbound JMS Gateways for request/reply operations.

Listing 22-74 below shows the maven dependency required for supporting JMS support using Spring Integration.

Listing 22-78 below shows configuring jms outbound channel adapter. In the below listing the configuration will produce an adapter that receives Spring Integration Messages from the “inputChannel” and then converts those into JMS Messages and sends them to the JMS Destination reference whose bean name is “outQueue”.

Listing 22-79 and Listing 22-80 below shows, configuring JMS inbound gateway and outbound gateway repectively, in the Spring configuration file.
