@EnableFeignClients和@FeignClient在自动装配'FeignContext'NoSuchBeanException时失败 [英] @EnableFeignClients and @FeignClient fail on Autowiring 'FeignContext' NoSuchBeanException

问题描述

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 。

The microservice I'm writting needs to communicate to other microservices in our platform. On that attempt, the ideal solution for us is Spring Cloud Netflix Feign, implemeting a @FeignClient.

但是，当我尝试 @Autowired ReviewProvider 时，我面临以下例外：

However, I'm facing the exception below when I try an @Autowired ReviewProvider:

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());
    }
}

推荐答案

似乎就像那里没有关于这个东西的解决方案...

Seems like there is not anything out there yet about the solution to this stuff...

这是我为解决这个问题所做的：
1.添加此注释到你的测试类：

Here is what I did to solve this: 1. Add this annotation to your test class:

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

试试吧，如果它不起作用，你可能需要 @EnableFeignClients 注释

Try it, if it does not work, you might need the @EnableFeignClients annotation on your main program config
