Java Spring Basics Spring Components and Configuring Our App Adding a Spring Configuration File

application fail to start

When I try to launch my app, it shows me this exception: Probably, someone knows how to solve it:)



The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.


Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.

Sounds like you have another thing running at port 8080. I thought I didn't, but then I went to 'localhost:8080' in my browser and saw something load. It was another Spring application I had running. I stopped that in IntelliJ, and I was able to move past this issue. Hope this helps!
