@EnableFeignClients和@FeignClient在自动连接"FeignContext"上失败 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。在这种尝试中,我们的理想解决方案是Spring Cloud Netflix假装,实现@FeignClient

但是,当我尝试@Autowired ReviewProvider时,我面临以下异常:

异常(原因(

@FeignClient("http://metadata-reviews")
public interface ReviewProvider {
    @RequestMapping(path = "sessions", method = POST)
    ReviewSessionDTO createSession();
}

评论提供者.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());
    }
}

似乎还没有关于这些东西的解决方案......

这是我为解决这个问题所做的:

  1. 将此注释添加到测试类:

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

试试吧,如果它不起作用,您可能需要主程序配置上的@EnableFeignClients注释

推荐的方法是对应用程序配置进行切片,这意味着您需要从 SpringBootApplication 中删除@EnableFeignClients

并添加专用配置类:

@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:

  • https://github.com/spring-projects/spring-boot/issues/7270
  • https://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#test-auto-configuration

我只是通过在我的类上@EnableAutoConfiguration注释来解决这个问题

你唯一必须做的:

  • 添加到构建文件中 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有注释@SpringBootApplication的类

我也遇到了这个问题,我遵循了Mariusz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 })

我必须添加基本包和配置

@Configuration
@EnableFeignClients( basePackages = ["com.yourcompany.yourproject"])
internal open class FeignConfiguration
