// attrs 用于表示注解@EnableFeignClients所在配置类的注解元数据中注解@EnableFeignClients // 的部分 Map<String, Object> attrs = metadata .getAnnotationAttributes(EnableFeignClients.class.getName()); AnnotationTypeFilter annotationTypeFilter = new AnnotationTypeFilter( FeignClient.class); final Class<?>...
这个方法就是使用了Spring的BeanDefinitionBuilder把FeignClientSpecification这个bean给注册到Spring容器中了。 然后我们继续放回到主方法中看下一个方法: image.png 这个方法根据名称registerFeignClients来说应该就是注册FeignClients类了,进入方法中,第一个scanner我们看下: protected ClassPathScanningCandidateComponentProvider...
Map<String, Object> attributes = annotationMetadata.getAnnotationAttributes(FeignClient.class.getCanonicalName()); String name=this.getClientName(attributes);//每个Feign的客户端的配置类封装成一个FeignClientSpecification的BeanDefinition,注册到spring容器中this.registerClientConfiguration(registry, name, attributes...
(Bean not found error for Feign client). Annotated config class is guru.sfg.brewery.beer_service.config.LocalDiscovery. Use case is setting up config without Eureka using RestTemplate for local dev, and a config with Eureka via active profiles. Based on the Javadoc of the annotation, I expect...
Good day ! Currently I have need to specify base packages in @EnableFeignClients annotation using spring placeholders, that it should automatically resolve. But I've been a little bit confused when those placeholder haven't been resolved...
@EnableFeignClients 注解一般是加在XxxApplication.java入口类上,但如遇到@FeignClient所在的包路径不从属于XxxApplication.java所在的package时,会导致feign调用不了。 自定义注解@EnableLock一般是作用于方法上,但是@Lock注解要生效的话,程序会需要知道扫码的包路径。为了减少业务方使用的时候额外配置,我们自动读取XxxApp...
@EnableEurekaClient @EnableFeignClients @EnableCircuitBreaker @EnableHystrix 他们都是@Enable开头,各自实现不同的功能,解析这种@Enable的逻辑是什么呢? @Enable驱动逻辑 找入口 @Enable的模块驱动,依赖于@Import实现。 @Import作用是装载导入类,主要包括@Configuration class,ImportSelector实现类,ImportBeanDefinitionRegi...
这个方法主要干了两件事儿,第一个方法是注册了默认的配置信息,第二个就是注册FeignClients,我们挨个一个个详细的看下: privatevoidregisterDefaultConfiguration(AnnotationMetadata metadata,BeanDefinitionRegistry registry){Map<String,Object>defaultAttrs=metadata.getAnnotationAttributes(EnableFeignClients.class.getName()...
