Connection refused on rabbitMq

rabbitmq:managementI have a docker image running in WSL2

But I keep getting an error when starting the java project

 Find a big guy's answer from the Internet to solve the problem:

 I reinstalled rabbitMq using the command:
docker run -d --hostname my-rabbit --name rabbit -p 15672:15672 -p 5671-5672:5671-5672 rabbitmq:3.8.0

Pay attention to your own installation version number, mine is 3.8.0,

Start the project again after installation, the problem is solved
