java当我为JerseyTest注册JacksonFeature时，我可以使用对Jackson ObjectMapper的引用吗？

Question

当我使用Jersey测试框架测试rest服务时，是否有可能在测试类中重用Jackson ObjectMapper引用

我在测试类扩展的抽象类中注册了JacksonFeature

public abstract class AbstractRestIntegrationTest extends JerseyTest {

    @Override
    protected Application configure() {

        ResourceConfig resourceConfig = new ResourceConfig(getResourceClass());
        resourceConfig.register(JacksonFeature.class);
        resourceConfig.register(MultiPartFeature.class);
        return resourceConfig;
    }
}

在我的测试类中，我调用rest服务，它返回给我json。然后我想通过jackson解析这个json，并检查它是否包含对象。我的问题是，当我注册JacksonFeature时，是否可以在Jersey的测试方法中重用ObjectMapper

public class ManagedElementIntegrationTest extends AbstractRestIntegrationTest {

       @Override
    protected Class<?> getResourceClass() {
        return ManagedElementRestService.class;
    }

    @Test
    public void testGetManagedElementById() throws IOException {
        IManagedElementService managedElementService = getBeanOfClass(IManagedElementService.class);

        ManagedElement me = prepareManagedElementObject();

        try {
            when(managedElementService.getUpdatedApplication(anyString())).thenReturn(me);
        } catch (ManagedElementNotFoundException e) {
            fail("Exception not expected: " + e);
        }

        String response = target("me/app").request().accept(MediaType.APPLICATION_JSON).get(String.class);
        ObjectMapper mapper = new ObjectMapper();
        JsonNode actualObj = mapper.readTree(response);
        assertNotNull(actualObj);
        assertNotNull(actualObj.get("mapPosition"));
        assertNull(actualObj.get("alarms"));

        // code continues below.
    }
}
