弹簧自动装配的HttpServletRequest的集成测试(Spring autowire Htt

我们有单控制器一样

@Controller
class C {
  @Autowire MyObject obj;
  public void doGet() {
    // do something with obj
  }
}

为MyObject是在过滤器/拦截器创建并投入HttpServletRequest的属性。那么它在@Configuration获得：

@Configuration
class Config {
  @Autowire
  @Bean @Scope("request")
  MyObject provideMyObject(HttpServletRequest req) {
      return req.getAttribute("myObj");
  }
}

工作一切良好，在主要的代码，但不是在测试：当我从一个集成测试运行：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/web-application-config_test.xml")
class MyTest {
    @Autowired
    C controller;

    @Test
    void test() {
       // Here I can easily create "new MockHttpServletRequest()"
       // and set MyObject to it, but how to make Spring know about it?
       c.doGet();
    }
}

它抱怨说NoSuchBeanDefinitionException: No matching bean of type [javax.servlet.http.HttpServletRequest] 。（起初，它抱怨请求范围不活跃，但我解决它使用CustomScopeConfigurer与SimpleThreadScope的建议在这里）。

如何让Spring注射知道我MockHttpServletRequest？或者直接MYOBJECT？

Workarounded是暂时的，但它看起来像正确的做法：在配置，而不是req.getAttribute("myObj")写

RequestAttributes requestAttributes = RequestContextHolder.currentRequestAttributes();
return (MyObject) requestAttributes.getAttribute("myObj", RequestAttributes.SCOPE_REQUEST);

所以它不会再需要一个HttpServletRequest的实例。并填写测试：

MockHttpServletRequest request = new MockHttpServletRequest();
request.setAttribute("myObj", /* set up MyObject instance */)
RequestContextHolder.setRequestAttributes(new ServletWebRequest(request));
