我按照此处的文档（https://docs.spring.io/spring-boot/docs/2.0.0.RC1/reference/htmlsingle/#production-ready-endpoints-enabling-endpoints）进行操作，并确保application.yml文件具有以下

management:
  metrics:
    export:
      prometheus:
        enabled: true
  endpoints:
    web:
      expose:
        health, info, httptrace, metrics, threaddump, mappings, prometheus

根据文档（https://docs.spring.io/spring-boot/docs/current-SNAPSHOT/actuator-api/html/#prometheus），以下操作无效。

curl 'http://localhost:8080/actuator/prometheus' -i

我得到404处理程序映射未找到异常。有人可以让我知道如何启用Prometheus端点进行抓取，以及需要使用哪个URL端点进行测试吗？

o.s.w.r.r.m.a.RequestMappingHandlerMapping[276] - Did not find handler method for [/actuator/prometheus]

所有其他端点的运行状况，信息，httptrace，线程转储，映射均正常运行。

我正在尝试使用 Webfilter 拦截 Spring Boot Webflux 应用程序（Spring boot 2.0.0.M7）中的所有请求，并检查“Authorization”标头是否存在。如果不存在，我想停止请求处理并发送自定义 HttpStatus 和自定义正文。自定义 HttpStatus 正在运行，但我无法将自定义消息写入 HTTP 正文。以下
