@EnableFeignClients 和@FeignClient 在自动装配时失败 'FeignContext' NoSuchBeanException

@EnableFeignClients and @FeignClient fail on Autowiring 'FeignContext' NoSuchBeanException

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。在那次尝试中,我们的理想解决方案是 Spring Cloud Netflix Feign,实施 @FeignClient.

但是,当我尝试 @Autowired ReviewProvider:

时遇到以下异常

异常(原因)

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());
    }
}

似乎还没有关于这个问题的解决方案...

这是我解决这个问题的方法:

  1. 将此注释添加到您的测试中 class:

    @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中添加 @EnableFeignClients 注解

推荐的方法是切片应用程序配置,这意味着您需要从SpringBootApplication.[=14中删除@EnableFeignClients =]

并添加专用配置class:

@Configuration
@EnableFeignClients
public class CloudConfiguration {

}

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

参考:

唯一你必须做的:

  • 添加到你的构建文件假依赖,例如,gradle

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

  • 将@FeignClient 添加到您的界面
  • 将@EnableFeignClients 添加到任何配置或添加到带有注释@SpringBootApplication
  • 的class

我通过在 class

上添加 @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。但是必须弄清楚一些事情所以放在这里......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 })
