Unable to run ZipKin server with spring boot

Question

Zipkin won't launch with spring boot. When I run the application from the server side (java), it throws this exception (probably a dependency issue, but I can't find it). I have tried many ways to troubleshoot it and have changed the spring versions each time i ran into difficulties.):

It is necessary to start rabbitmq first?

What is the best way to launch zipkin in spring boot?

Why would it be a good idea to run Zipkin with spring boot?

Answer 1

1. Copy the zipkin jar under src/main/resources

2.  <plugin> <groupId>com.coderplus.maven.plugins</groupId> <artifactId>copy-rename-maven-plugin</artifactId> <version>1.0.1</version> <executions> <execution> <id>copy-file</id> <phase>verify</phase> <goals> <goal>copy</goal> </goals> <configuration> <sourceFile>src/main/resources/zipkin-server-2.22.1-exec.jar</sourceFile> <destinationFile>${project.build.directory}/${project.build.finalName}.jar</destinationFile> </configuration> </execution> </executions> </plugin>
