Spring Boot App is not showing in Axon Dashboard

I am new to Spring Boot CQRS pattern.

I have a Spring boot app and I am running the Axon server on my localhost using the jar version.

However, my app does not show up in the Axon Dashboard.

Axon Dashboard

Also I am getting the below error when I try to run my application.

Consider defining a bean of type 'org.axonframework.commandhandling.gateway.CommandGateway' in your configuration.

I tried searching on Stackoverflow but could not find any solutions.

Solution

  • Axon Framework doesn't work with Spring Boot 3 yet. We are looking into a solution, so hopefully Axon Framework 4.7.0 will be compatible with Spring Boot 3.
