求助问答

我在使用gateway做网关时候，添加了一个过滤器，过滤器中通过feign远程调用了其他程序中的方法。
但是在程序执行过滤器的时候出现了报错，报错内容如下：

我也遇到了同样的问题，贴主找到方法了吗

3

很遗憾，还没有 :sweat_smile:

4

看异常信息，是没有找到HttpMessageConverter？？？。。是不是 feign 远程调用，得到的响应数据在gateway 中没有对应的消息转换器来解析啊？

我猜的，我不熟悉这个。

5

终于搞定了。通过调试源码，发现 HttpMessageConverters 注入失败，找到一个类似的问题，2018-03-29 SpringCloud Feign Decoder - 简书 。然后就配置了一个 feignDecoder，解决！ :grinning:

你好，我也碰到同样的问题。根据你提供的链接文章，在代码中配置了，但还是报同样的错误，请问可以贴下你的这个配置类我看看吗

8

谢谢楼主 可以了，我稍微改了下代码

我直接配了一个转换器解决

@Configuration
public class GatewayConfig {

    @Bean
    KeyResolver userKeyResolver() {
        return exchange -> Mono.just(Objects.requireNonNull(exchange.getRequest().getRemoteAddress()).getAddress().getHostAddress());
    }

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

debug找到了一个是HttpMessageConverters没有自动注入。
我也注入了这个bean，解决了这个问题。
但是我不知道，为什么这个bean没有自动注入？之前使用的时候都是正常的。

HttpMessageConvertersAutoConfiguration这个类有个自动注入的条件
@Conditional(NotReactiveWebApplicationCondition.class)，不是reactive的web才会被注入。
