@EnableFeignClients和@FeignClient在自动布线“假装文本”NoSuchBeanException上失败

java spring-boot feign spring-cloud-netflix spring-cloud-feign

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 Feign，它体现了@FeignClient。

但是，当我尝试时，我遇到了以下异常：@Autowired ReviewProvider

异常（原因）

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

@FeignClient("http://metadata-reviews")

        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());
    }
}

答案 1

似乎还没有关于这个东西的解决方案......

以下是我为解决这个问题所做的：

将此注释添加到测试类中：

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

试试看，如果它不起作用，你可能需要在主程序配置上注释@EnableFeignClients

答案 2

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 SpringBootApplication 中的默认配置。
