How do I configure a Json provider for a JAX-RS test client using Spring?

I have set up a JAX-RS service using Apache CXF, which I would like to test using Apache CXF JAX-RS' Client API. The server has been configured to use Jackson as the json provider. Now I would like to do the same for the client: that is, letting Jacson handle the conversion to/from json.

Unfortunately I am unsure of how to "spring enable" the tests, having only superficial knowledge of Spring. I got away with programmatically setting up a provider in the test, but would like to know how to do it through Spring. So instead of

@BeforeClass
public static void setup() {
    ProviderFactory.getSharedInstance().registerUserProvider(new JacksonJsonProvider());
}

I would want to just set it in springConfiguration.xml (or something like that :). When setting up the serverside, springConfiguration.xml looked like this.

<bean id="jsonProvider" class="org.codehaus.jackson.jaxrs.JacksonJsonProvider"/>

<jaxrs:server id="restContainer" address="/">
    <jaxrs:serviceBeans>
        <ref bean="echoServi开发者_如何学运维ce"/>
    </jaxrs:serviceBeans>

    <jaxrs:providers>
        <ref bean="jsonProvider" />
    </jaxrs:providers>

    <jaxrs:extensionMappings>
        <entry key="json" value="application/json"/>
    </jaxrs:extensionMappings>
</jaxrs:server>

I tried to just add

<jaxrs:client id="restClient" >
    <jaxrs:providers>
        <ref bean="jsonProvider" />
    </jaxrs:providers>
</jaxrs:client>

to springConfiguration.xml, but that did not do anything. No surprise, as I have not set up my JUnit tests to use Spring ... Could anyone tell me how to do this, or point me to any good resources with which I could assemble the necessary info?

The following annotations will load your application context prior to tests being run.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"applicationContext.xml"}) 
public class JaxRsTest {

  @Autowired
  MyBean myBean

  public void testMyBean() {
    //add some real tests here...
    assertNotNull(myBean)
  }

}
