如何使用 Spring Cloud Sleuth 和 Spring Cloud Gateway 删除 WARN 消息

Question

我需要在 Netty 日志中记录跟踪，所以我添加了这个配置：

@Configuration
public class SleuthGWConfiguration {

    @Bean
    public HttpClientCustomizer customizer(HttpTracing httpTracing) {
        return (c) -> {
            return ReactorNettyHttpTracing.create(httpTracing).decorateHttpClient(c);


        };
    }
}

并且日志包含预期的跟踪：

但是带有警告消息一大堆应用程序启动时出现跟踪 (complete stack trace is here)：

[36mo.s.c.s.a.i.w.SkipPatternConfiguration  [0;39m [2m:[0;39m Most likely, there is an actuator endpoint that indirectly references an instrumented HTTP client. An exception was thrown during bean initialization. Will ignore that exception

经过调查，我找到了the related issue。似乎这不会导致真正的问题，但我想知道是否可以创建一个配置来防止在启动时引发异常。

示例项目是available here。

只需设置属性logging.level.org.springframework.cloud.sleuth.autoconfig.instrument.web.SkipPatternConfiguration=ERROR。你可以这样做，例如通过application.yml
