We have slueth in other microservices and we wants to send data to zipkin server for consolidated logging.I am trying to start my zipkin server.I am getting the following error:

Any suggestions will be helpful.
You should create application.properties file and after that you should add the following
Your application.properties :
server.port:9411 // Not Required
management.metrics.web.server.auto-time-requests=false //Required
Your main class :
import zipkin.server.EnableZipkinServer;
#EnableZipkinServer
#SpringBootApplication
public class ZipkinServerApplication {
public static void main(String[] args) {
SpringApplication.run(ZipkinServerApplication.class, args);
}
}
Your Pom.xml :

Your zipkin port :

class path resource [org/springframework/web/reactive/config/DelegatingWebFluxConfiguration.class] cannot be opened because it does not exist

I am following https://spring.io/guides/gs/accessing-data-mysql/ on my IntelliJ.
however after I excuted spring-boot:run command, below error happens
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [org.springframework.boot.autoconfigure.web.reactive.WebFluxAutoConfiguration$WebFluxConfig]; nested exception is java.io.FileNotFoundException: class path resource [org/springframework/web/reactive/config/DelegatingWebFluxConfiguration.class] cannot be opened because it does not exist
I totally followed the offical guide. So what I am missing?

I think your main class is wrong and you are using something like this:
SpringApplication.run(SpringBootApplication.class);
Please be sure that SpringApplication.run() method is called over your main class (MainApplication in below exmple):
#SpringBootApplication
public class MainApplication{
public static void main(String[] args){
SpringApplication.run(MainApplication.class, args);
}
}

Spring boot does not compatible with Eureka server

I have build an application that is a Eureka server, service registry.
The pom.xml is as following:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

<plugin>

and the main class that is run the application is as following:
package org.eureka.server;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
#SpringBootApplication
#EnableEurekaServer
public class EurekaServiceApplication {
public static void main(String[] args) {
//ApplicationContext ctx = new SpringApplicationBuilder().bannerMode(Banner.Mode.CONSOLE).run(args);
SpringApplication.run(EurekaServiceApplication.class, args);
}
}
And the application.yml is just this:
server:
port: 8761
When it is run by clean spring-boot:run command, the following exception is raised:
Caused by: java.lang.NoSuchMethodError:

When I remove the eureka dependency in pom.xml, the application is run successfully.
Where is wrong?
