Lior Okman commented on OLINGO-193:
-----------------------------------
The attached patch provides two items:
1. A version of ODataRootLocator that can be used by Spring to wire the OData
service
Using just this file, the usage becomes:
1.1 Add the CXFServlet fragment to web.xml
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
<!-- Don't forget to configure the listener as per Spring's requirement -->
</listener>
<servlet>
<display-name>CXFServlet</display-name>
<servlet-name>CXFServlet</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
1.2 Create a ServiceFactory and wire it into Spring
<bean
class="com.sap.roolingo.odata.MyServiceFactory" id="odataServiceFactory"/>
1.3 Expose the OLingo service like this:
<bean id="rootLocator"
class="org.apache.olingo.odata2.core.rest.spring.ODataRootLocator" >
<property name="serviceFactory" ref="odataServiceFactory" />
</bean>
<bean id="exceptionhandler"
class="org.apache.olingo.odata2.core.rest.ODataExceptionMapperImpl"/>
<bean id="provider"
class="org.apache.olingo.odata2.core.rest.app.ODataApplication.MyProvider"/>
<jaxrs:server id="SomeIdForTheService" address="/OData.svc">
<jaxrs:serviceBeans>
<ref bean="rootLocator"/>
<ref bean="exceptionhandler"/>
<ref bean="provider" />
</jaxrs:serviceBeans>
</jaxrs:server>
2. The olingo-spring module which provides a Spring namespace handler that
allows the entire Spring configuration (item 1.3 above) to be replaced with the
following:
<odata:server address="/OData.svc" factory="odataServiceFactory"
id="SomeIdForTheService"/>

> URL: https://issues.apache.org/jira/browse/OLINGO-193
> Project: Olingo
> Issue Type: New Feature
> Components: odata2-core
> Environment: Spring
> Reporter: Jan Penninkhof
> Assignee: Michael Bolz
> Priority: Minor
> Labels: spring
> Attachments: spring.diff

>
> Currently only a imlementation scenario using CXFNonSpringJaxrsServlet is
> provided. However, to implement OLingo while bootstrapping Spring at the same
> time, this scenario won't work. Instead probably CXFServlet should be used
> instead.
> However, CXFServlet has quite a different API and Olingo currently doesn't
> have wiring to that API.
> It would be excellent if there would be a version of Olingo that could work
> in a Spring environment as well, e.g. to allow for reuse of existing Spring
> components.
