Spring Boot: Cannot access REST Controller on localhost (404)

Question

I am trying to adapt the REST Controller example on the Spring Boot website. Unfortunately I\'ve got the following error when I am trying to access the localhost:8080/

Answer 1

It could be that something else is running on port 8080, and you're actually connecting to it by mistake.

Definitely check that out, especially if you have dockers that are bringing up other services you don't control, and are port forwarding those services.
