Spring Cloud Gateway通过feign调用微服务报：: ...HttpMessageConverters‘ available:

问题 : No qualifying bean of type '' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@(required=true)} 的解决方案：

Spring Cloud Gateway是基于WebFlux的，是ReactiveWeb，所以HttpMessageConverters不会自动注入。在gateway服务中配置以下Bean，即可解决。

@Bean
@ConditionalOnMissingBean
public HttpMessageConverters messageConverters(ObjectProvider<HttpMessageConverter<?>> converters) {
	return new HttpMessageConverters(().collect(()));
}
