Re: [Resteasy-developers] Fwd: Problem with Spring and RestEasy integration

I'm having trouble making the problem easy to reproduce... it happens
sometimes, but not always.
One thing I noted that is different in your tests from ours is that you
don't have a method answering a URL directly (without sub-resources) and
using a spring injected bean, which is our case. I changed our local test to
use a sub-resource and the problem seemed to vanished, although I cannot be
100% sure yet.
I could not make your environment run here, but I'll write down what I think
could be a test case for my scenario, that could be inserted in the
SmokeTest.
This is the new block test:
GetMethod method = new GetMethod("
http://localhost:8080/spring-integration-test/direct/direct-call");
int status = client.executeMethod(method);
Assert.assertEquals(HttpResponseCodes.SC_OK, status);
Assert.assertEquals("DIRECT OK", method.getResponseBodyAsString());
method.releaseConnection();
To implement this, we could use the following bean:
@Path("/direct")
@Service("direct")
public class DirectBean {
@GET
@Path("direct-call")
public String directCall() {
return directSpring.getDirectResult();
}
@Resource(name="directSpring")
private DirectSpring directSpring;
}
and the spring bean:
@Service("directSpring")
public class DirectSpring {
public String getDirectResult() {
return "DIRECT OK";
}
}
does this make sense? Does it make the problem easier to understand?
PS.: If this really reproduces our problem, you may have to run the test
some times before the error appears, since it works sometimes.
