Mule Spring Proxies

Mule Spring Proxies is a springified alternative to MuleClient. This approach makes it possible configure and inject a Mule client using Spring. The module might be a part of the SMuT Stack (the combination of Spring, Mule and Tomcat that many people use as a lightweight app server). Main goal of the module is to simplify interaction between services outside Mule and Mule services(UMO:s) using Spring configuration.

Planned approach

Implement the skeleton
Implement support for synchronous calls using the vm transport
Add other transports and transformers
Implement support for asynchronous calls

Example of intended usage

Spring configuration of the ProxyFactoryBean:

<bean id="proxyToMuleService" class="org.mule.springproxies.SynchClientFactoryBean">
  <!-- Service interface implemented by Mule Service -->
  <property name="serviceInterface"; value="no.bouvet.samples.AService" />

  <!-- Endpoint configured in Mule configuration -->
  <property name="endpointAdress" value="vm://testIn" />
</bean>

Spring 2.0 schema configuration of the ProxyFactoryBean:

<clprx:synch
  id="proxyToMuleService"
  serviceInterface="no.bouvet.samples.AService"
  endpointAdress="xfire:http://localhost:8081/services/AServiceUMO"
  resultTransformer="no.bouvet.samples.AServiceTransformer"/>

Client bean getting the proxy injected:

<bean id="theUsingBean" class="no.bouvet.samples.SomeBeanLivingInSpringContainer">
  <property name="aService" ref="proxyToMuleService" />
</bean>

Since there isn't any code so far there's a simple POC attached. The POC includes a test case showing how to use the Spring proxies as Mule clients.
