org.springframework.integration.adapter.httpinvoker
Class HttpInvokerGateway

java.lang.Object
  org.springframework.integration.gateway.MessagingGatewaySupport
      org.springframework.integration.gateway.SimpleMessagingGateway
          org.springframework.integration.adapter.AbstractRemotingGateway
              org.springframework.integration.adapter.httpinvoker.HttpInvokerGateway

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean, MessageBusAware, MessagingGateway, MessageHandler, org.springframework.web.HttpRequestHandler

public class HttpInvokerGateway
extends AbstractRemotingGateway
implements org.springframework.web.HttpRequestHandler, org.springframework.beans.factory.InitializingBean

A gateway adapter for HttpInvoker-based remoting. Since this class implements HttpRequestHandler, it can be configured with a delegating Servlet where the servlet-name matches this adapter's bean name. For example, the following servlet can be defined in web.xml:

 <servlet>
     <servlet-name>httpInvokerGateway</servlet-name>
     <servlet-class>org.springframework.web.context.support.HttpRequestHandlerServlet</servlet-class>
 </servlet>
 

And, this would match the following bean definition in the application context loaded by a org.springframework.web.context.ContextLoaderListener:

 <bean id="httpInvokerGateway" class="org.springframework.integration.adapter.httpinvoker.HttpInvokerGateway">
     <constructor-arg ref="requestChannel"/>
 </bean>
 

Alternatively, in a Spring MVC application, the DispatcherServlet can delegate to the "httpInvokerGateway" bean based on a handler mapping configuration. In that case, the HttpRequestHandlerServlet would not be necessary.
