Spring boot rest controller not mapped

Question

I'm building simple test Rest api, basically when /testing is called it will create an logging object and send that to another api ( seperate project and its running). But whenever going to /test not going through the controller.The weird part is, it was working before. I included logging.level.org.springframework.web = DEBUG in application.properties.Below are the log and my source files.

Answer 1

Your RestController isn't called because You added @ComponentScan annotation with fixed basePackages to your TestProjectApplication.java which doesn't include package with your controller. It means that Spring will never scan your controller package and it can't register any endpoints.

To fix that just simply remove @ComponentScan from your TestProjectApplication.java , default behaviour is scanning all packages, so your controller will be again reachable.
