我正在编写的微服务需要与我们平台中的其他微服务进行通信。在这次尝试中,我们的理想解决方案是 Spring Cloud Netflix Feign ,实现 @FeignClient

但是,当我尝试@Autowired ReviewProvider

时,我正面临下面的例外情况

例外(原因)

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.cloud.netflix.feign.FeignContext' available

ReviewProvider.java

@FeignClient("http://metadata-reviews")
public interface ReviewProvider {

    @RequestMapping(path = "sessions", method = POST)
    ReviewSessionDTO createSession();

}

ReviewProvider.java

@RunWith(SpringRunner.class)
@ActiveProfiles(INTEGRATION)
@ContextConfiguration(classes = AppEntry.class)
@AutoConfigureTestDatabase(replace = Replace.NONE)
@DataJpaTest
public class ReviewProviderTest {

    @Autowired
    private ReviewProvider provider;
    private Class<? extends ReviewProvider> providerClass;

    @Before
    public void setup() {
        providerClass = provider.getClass();
    }

    @Test
    public void classAnnotations() {
        assertTrue(providerClass.isAnnotationPresent(FeignClient.class));
        assertEquals("http://metadata-reviews", providerClass.getAnnotation(FeignClient.class).value());
    }

    @Test
    public void createSession() throws Exception {
        final Method method = providerClass.getDeclaredMethod("createSession");
        assertTrue(method.isAnnotationPresent(RequestMapping.class));

        final RequestMapping mapping = method.getAnnotation(RequestMapping.class);
        assertEquals("sessions", mapping.path());
        assertEquals(0, method.getParameters().toString());
    }
}

似乎没有关于这些东西的解决方案......

以下是我为解决此问题所做的工作: 1.将此注释添加到测试类中:

@ImportAutoConfiguration({RibbonAutoConfiguration.class, FeignRibbonClientAutoConfiguration.class, FeignAutoConfiguration.class})

尝试一下,如果它不起作用,您可能需要在主程序配置上使用@EnableFeignClients注释

推荐的方法是切片应用程序配置,这意味着您需要从 SpringBootApplication 中删除$ awk -F';' '$3=="HC"{if (NR>1) print s; s=0; next} {s+=$3} END{print s}' file 14 28 51 0 37 10

并添加专用配置类:

@EnableFeignClients

这是必需的,因为所有切片注释(如@WebMvcTest)都包含 SpringBootApplication 的默认配置。

唯一必须做的事情:

  • 添加到您的构建文件假装依赖项,例如,对于gradle

编译'org.springframework.cloud:spring-cloud-starter-feign'

  • 将@FeignClient添加到您的界面
  • 将@EnableFeignClients添加到任何配置或带注释的类@SpringBootApplication

我仅通过类上的@EnableAutoConfiguration注释解决了这个问题

我也遇到了这个问题,我遵循了 MariuszS 的回答。但是必须弄清楚几件事所以放在这里......我们需要告诉@SpringBootTest 从哪里获取配置,所以它会像这样

@SpringBootTest
@ContextConfiguration(classes = { YourClientConfig.class })
