jersey2 Unit testing,HttpServletRequest is null

Question

Ask everybody to help?

jersey Bug connection: [1]: https://java.net/jira/browse/JERSEY-2412

The servlet request, response and context not injected into the class when I using test provider (tested jetty and grizzly2). I using packages annotation to pull up the application.

Do you have any other way?

 public class VMResourceTest extends BaseTest {  

    @Test  
    public void testCreateVm() {  

    String bodyData = loadClassPathData(CLASS_PATH+File.separator+"tools"+File.separator+"createVm.json");  
        Response response = target("/tool/cloud/vrm/fm/ghca_vms").queryParam("platform_id", "A22A4B0C3AEC49F5916EA8CC01F56E9A")  
                    .request().header("X-Auth-GHCA-User-ID", "X-Auth-GHCA-User-ID")  
                    .post(Entity.entity(bodyData, MediaType.APPLICATION_JSON));  
        assertEquals("200", response.getStatus());  
    }  
}

        rc.register(SpringLifecycleListener.class);  
        rc.register(RequestContextListener.class);  

        rc.property("contextConfigLocation", "classpath:spring/spring-config.xml");  
        return rc;

        public String loadClassPathData(String classFilePath){

           String result = "";  
        try {

            BufferedReader br = new BufferedReader(new  FileReader(schemaContextFile));
            String s = null;  
            while((s = br.readLine())!=null){ 
                result = result + "\n" +s;  
            }  
            br.close();      
        } catch (IOException e) {  
            e.printStackTrace();  
        }  
        return result;  
    }  
    }

    @Component  
    @Path("tool/cloud/vrm")  
    public class VMResource extends BaseResource{  

    @Autowired  
    private VMService vmService;  

    @Context  
    public HttpServletRequest request;  
    @Context  
    public HttpServletResponse response;  


    @POST  
    @Path("{platform_type}/ghca_vms")  
    @Consumes({MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})  
    @Produces({MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})  
    public Response createVm(@PathParam("platform_type") String platformType,  
            @QueryParam("platform_id") String platformId) {}  

request and response is null.

You need to configure the JerseyTest for a Servlet environment. In your JerseyTest, you should have something like

@Override
protected TestContainerFactory getTestContainerFactory() {
    return new GrizzlyWebTestContainerFactory();
}

@Override
protected DeploymentContext configureDeployment() {
    ResourceConfig config = new ResourceConfig(SessionResource.class);
    return ServletDeploymentContext.forServlet(
                             new ServletContainer(config)).build();
}

If you look at the ServletDeploymentContext.forServlet, it returns a ServletDeploymentContext.Builder. If you look at the Javadoc, you will see some familiar looking methods, like initParam(...,...), addListener, etc. This is just like building your web.xml programmatically. Just keep chaining methods, then build.

With the above configuration, you no longer need to override the configure method in the JerseyTest. Just add the ResourceConfig like seen above.
