Question

我们有像

这样的单件控制器

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

MyObject是在过滤器/拦截器中创建的，并放入HttpServletRequest属性中。然后它在@Configuration：

中获得

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

一切都在主代码中运行良好，但在测试中却没有：当我从集成测试中运行它时：

@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NoSuchBeanDefinitionException: No matching bean of type [javax.servlet.http.HttpServletRequest]。（首先，它抱怨请求范围不活跃，但我使用CustomScopeConfigurer和SimpleThreadScope解决了它，如建议here）。

如何让Spring注入了解我的MockHttpServletRequest？或直接MyObject？

Answer 1

临时工作，但它看起来是正确的方法：在Config中，而不是req.getAttribute("myObj")，写

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

因此它不再需要HttpServletRequest实例。并填写测试：

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

Spring集成测试中的autowire HttpServletRequest
