Web Services
Spring Integration provides two ways by it supports web services as follows:
- Invoking a web service by sending a message to a channel using an outbound web service gateway
- Sending a message to a channel upon receiving a web service invocation using an inbound web service gateway
Spring Integration provided inbound and outbound gateways include support for adding an XML marshaller and provides both client and server support for web services. Spring Integration builds upon the Spring Web Services project and the required Maven dependencies for the Spring Integration web services gateways are as shown in Listing 22-81 below.

Listing 22-83 below shows configuring web service inbound gateway in the Spring configuration file. It also uses a marshaller and unmarshaller that will do the necessary marshaling and unmarshalling of the web service calls.

Listing 22-84 below shows configuring web service outbound gateway in the Spring configuration file. Similar to inbound gateway shown in the previous code snippet, it also uses a marshaller and unmarshaller that will do the necessary marshaling and unmarshalling of the web service calls.
