Hi Matt,
The problem is in your BarResourceRestTest class you are not
configuring Jersey to use Spring.
The following does not set up the Jersey Spring configuration:
threadSelector = GrizzlyWebContainerFactory.create(baseUri,
initParams);
You might be able to do this:
threadSelector = GrizzlyWebContainerFactory.create(
com.sun.jersey.spi.spring.container.servlet.SpringServlet.class,
baseUri,
initParams);
But i really do not know how the Jersey configuration will get access
to the application context you have declared via the annotation. It
might be necessary to extend the Jersey SpringServlet in such a case.
The SpringServlet.initiate method is as follows:
@Override
protected void initiate(ResourceConfig rc, WebApplication wa) {
try {
final WebApplicationContext springWebContext =
WebApplicationContextUtils.
getRequiredWebApplicationContext(getServletContext());
final ConfigurableApplicationContext springContext =
(ConfigurableApplicationContext)springWebContext;
wa.initiate(rc, new SpringComponentProviderFactory(rc,
springContext));
} catch( RuntimeException e ) {
LOGGER.log(Level.SEVERE, "Exception occurred when
intialization", e);
throw e;
}
}
The jersey-spring module uses Grizzly for unit tests. See the
following class for the setup:
https://jersey.dev.java.net/source/browse/*checkout*/jersey/trunk/jersey/contribs/spring/src/test/java/com/sun/jersey/spring/AbstractResourceTest.java
Note that with Spring integration it is not necessary to explicitly
register resource and provider classes if those classes are also
Spring registered. See here for more details:
https://jersey.dev.java.net/source/browse/*checkout*/jersey/tags/jersey-1.0.2/api/contribs/jersey-spring/index.html
