Ip address without port not working

I run a docker container for my application. This is the command I used to get it worked:

docker run --name spring-boot -p 8080:8080 --link my-mysql-db:mysql -d username/image-name:latest

My application is up and running. I can navigate my app like this: http://111.22.222.222:8080 but it is not working if I type only http://111.22.222.222 without port number. How can I fix that?

Thank in advance!
