Spring 使用Mock RestEasy框架时没有标题

我试图使用服务器端resteasy模拟框架来发出GET请求，但是当试图从服务器代码中检索头时，它根本不存在

下面是测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:base-spring-context.xml" }, loader = DelegatingSmartContextLoader.class)
@DirtiesContext(classMode = ClassMode.AFTER_CLASS)
public class TestClass {

// Sets up RESTEasy processors to test @Provider classes
@Configuration
static class ContextConfiguration {

    @Autowired
    private ApplicationContext context;

    @Bean
    public Dispatcher getDispatcher() {
        Dispatcher dispatcher = MockDispatcherFactory.createDispatcher();
        dispatcher.getRegistry().addResourceFactory(getSpringResourceFactory());
        return dispatcher;
    }

    @Bean
    public SpringBeanProcessor getRSPostProcessor() {
        SpringBeanProcessor processor = new SpringBeanProcessor(getDispatcher(), getDispatcher().getRegistry(),
                getDispatcher().getProviderFactory());
        return processor;
    }

    @Bean
    public SpringResourceFactory getSpringResourceFactory() {
        SpringResourceFactory noDefaults = new SpringResourceFactory("restClass", context,
                RestClass.class);
        return noDefaults;
    }
}

@Autowired
Dispatcher dispatcher;

@Autowired
private ServletContext servletContext;

@Before
public void setUp() {
    ResteasyProviderFactory.getContextDataMap().put(HttpServletRequest.class, new MockHttpServletRequest(servletContext));
}

@Test
public void testRest() throws URISyntaxException, ECUNotFoundException {
    MockHttpRequest request = MockHttpRequest.get("/")
            .header("someHeader", "VALUE")
            .accept("application/myValue+XML");
    logger.info("HEADERS: {}",request.getHttpHeaders().getRequestHeader("someHeader"));
    MockHttpResponse response = new MockHttpResponse();
    dispatcher.invoke(request, response);
    logger.info("Got response: \n\tStatus: '{}'\n\tResponse body: '{}'",response.getStatus(),new String(response.getOutput()));
}
}

下面是Rest方法从RestClass触发的方法

@GET
@Path("/")
@Produces("application/myValue+XML")
@GZIP
public Response getMethod(@Context HttpServletRequest request) {
    String header = request.getHeader("someHeader");
        logger.info("HEADER NAME: {}","someHeader");
        if (header == null || header.isEmpty()) {
            logger.warn("the header must be present in the request");
            return Response.status(Status.BAD_REQUEST).build();
        }

这里的问题是Rest方法不接收头。但是，当测试方法的打印输出清楚地显示设置了标题时，它为空

谁能帮助理解为什么会发生这种情况
