My Microservices application has 3 different Microservices. many of them have been created with just spring boot (imperative way) but those application's tracings are shown in the dashboard correctly. but I created one Microservice application by using spring boot 3 with webflux. because of using spring boot 3 I had to use micrometer instead of sleuth.

我的微服务应用程序有3个不同的微服务。它们中的许多都是使用Spring Boot(命令式方式)创建的，但这些应用程序的轨迹在仪表板中显示正确。但我创建了一个微服务应用程序，使用的是带有WebFlux的Spring Boot3。因为我用的是弹簧靴3，所以我不得不用千分尺而不是探头。

My 3rd application does make a http request to the webflux application. but that trace details I can't see in the dashboard under the same trace. that trace (webflux one) is shown as a separate one in the dashboard. other 3 Microservices' tracing details are available under one trace. but webflux's trace is not.

我的第三个应用程序确实向WebFlux应用程序发出了一个http请求。但我在仪表板上同样的痕迹下看不到这些痕迹的细节。该跟踪(Webflow One)在仪表板中显示为单独的跟踪。在一个跟踪下可以找到其他3个微服务的跟踪详细信息。但WebFlux的踪迹却并非如此。

the pom.xml file and configuration like below.

package com.example.service6;

I tried lots of examples in the website but I was unable to do that. please help me to solve this problem.

我在网站上尝试了很多例子，但我做不到。请帮我解决这个问题。

For webflux Please make sure your reactor-core is >= 3.5.7 and micrometer context-propagation library which should be >=1.0.4

对于网络流量，请确保您的反应堆核心>=3.5.7，微米上下文传播库应>=1.0.4

you can get more information about this bug here

您可以在此处获取有关此错误的更多信息

Also please add this in your main class

另外，请在您的主类中添加此内容

Hooks.enableAutomaticContextPropagation();

Hooks.enableAutomaticContextPropagation()；

Add propagation type in your properties file as b3. because zipkin does support B3.

在属性文件中将传播类型添加为b3。因为Zipkin确实支持B3。

management.tracing.propagation.type=b3
