How to share cxf:bus over multiple osgi bundles on karaf? - cxf

Question

In my application, I have 2 bundles. Both are using cxf to create Restful server.
In those bundles I load cxf via blueprint. I define cxf:bus on those bundles with the same id to expect that two bundle will share the same bus instance then I can configure a Authentication interceptor on one bundle and It will apply for the other bundle also.
They looks like below.
Bundle 1:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jaxrs="http://cxf.apache.org/blueprint/jaxrs"
xmlns:cxf="http://cxf.apache.org/blueprint/core"
xsi:schemaLocation="
http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
http://cxf.apache.org/blueprint/jaxrs http://cxf.apache.org/schemas/blueprint/jaxrs.xsd
http://cxf.apache.org/blueprint/core http://cxf.apache.org/schemas/blueprint/core.xsd
">
<bean id="authInterceptor" class="com.dasannetworks.vn.rest.impl.AuthInterceptorImpl"></bean>
<cxf:bus id="my-app-bus" name="tutorial">
<cxf:inInterceptors>
<ref component-id="authInterceptor"/>
</cxf:inInterceptors>
</cxf:bus>
<bean id="Rest1ServiceImpl"class="com.dasannetworks.vn.rest.impl.Rest1ServiceImpl"></bean>
<bean id="jsonProvider" class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
<property name="serializeAsArray" value="true"/>
<property name="dropRootElement" value="true"/>
<property name="supportUnwrapped" value="true"/>
</bean>
<jaxrs:server id="custom1Service" address="/rest1">
<jaxrs:serviceBeans>
<ref component-id="rest1ServiceImpl"/>
</jaxrs:serviceBeans>
<jaxrs:providers>
<ref component-id="jsonProvider"/>
</jaxrs:providers>
</jaxrs:server>
Bundle 2:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jaxrs="http://cxf.apache.org/blueprint/jaxrs"
xmlns:cxf="http://cxf.apache.org/blueprint/core"
xsi:schemaLocation="
http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
http://cxf.apache.org/blueprint/jaxrs http://cxf.apache.org/schemas/blueprint/jaxrs.xsd
http://cxf.apache.org/blueprint/core http://cxf.apache.org/schemas/blueprint/core.xsd
">
<cxf:bus id="my-app-bus" bus="tutorial"></cxf:bus>
<bean id="rest2Service" class="com.dasannetworks.vn.rest2.impl.Rest2ServiceImpl" />
<jaxrs:server id="custom2Service" address="/rest2">
<jaxrs:serviceBeans>
<ref component-id="rest2Service"/>
</jaxrs:serviceBeans>
After installing and run:
The outcome:
all rests request to "/cxf/rest1/" will run into authInterceptor whereas all rests request to "cxf/rest2" are not.
Could anyone give me some advice about how to share the same cxf:bus on both bundles ?
Thank you in advance.

Answer 1

Since I cannot solve this problem with blueprint, I changed the way to fix it.
Instead of blueprint, I initiated CXF Bus Rest Server with Activator.
Bundle 1 Activator:
In bundle 1, I get the default bus and add authentication interceptor on it then register a Rest Server endpoint on it.
public void start(BundleContext bundleContext) throws Exception {
Bus defaultBus = BusFactory.getDefaultBus();
defaultBus.setId("my-app-bus");
BusFactory.clearDefaultBusForAnyThread(defaultBus);
System.out.println(this.getClass().getName());
System.out.println(defaultBus.getId());
defaultBus.getInInterceptors().clear();
defaultBus.getInInterceptors().add(new AuthInterceptorImpl());
JAXRSServerFactoryBean sf = new JAXRSServerFactoryBean();
sf.setBus(defaultBus);
sf.setAddress("/tutorial");
sf.setServiceClass(HelloRestServiceImpl.class);
sf.create();
}
In bundle 2,
Bundle 2 Activator
I get the default bus, register and set that bus for Rest Server.
#Override
public void start(BundleContext bundleContext) throws Exception {
Bus defaultBus = BusFactory.getDefaultBus();
List<Interceptor<? extends Message>> inInterceptors = defaultBus.getInInterceptors();
for(Interceptor interceptor: inInterceptors) {
System.out.println( interceptor.getClass().getName());
}
JAXRSServerFactoryBean sf = new JAXRSServerFactoryBean();
sf.setBus(defaultBus);
sf.setAddress("/Rest2");
sf.setServiceClass(Rest2ServiceImpl.class);
sf.create();
}
==> The result : both bundles are now use the same bus, and bundle 2 can run into authentication interceptor which I registered on bundle 1 also. !!!
