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(

@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:
-
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
