If you are using `spring-boot` then a embedded tomcat herewith. You do not need to deploy it on another tomcat server, rather package it to `jar` `jar` and after building run your application using the command `java -jar abc.jar` — Ataur Rahman Munna, Dec 05 '17 at 04:59
In my case, I had removed the `ROOT` directory from `webapps` because I was not using the root context. I was only using the full URL like `www.example.com/myAppName`. Still I started getting 404. It works after putting back the `ROOT` directory. Trying to figure out why... — Kartik, Dec 05 '17 at 05:38

run your spring boot app in your tomcat server as a ROOT context.

u can do it by change ROOT.war in tomcat server with your spring boot app ( this is a bad way ) or u can configure it.

Yes I had the similar error, in my case I autowire the object of Spring security session so it shows circular reference error. I added @Lay annotation on top of the autowired object. For more details pls check the link.

I fixed similar issue. There is no error but some warning when you try open web page. Probably you can take "Warning: No mapping found". You dont need to SpringBootServletInitializer and override metode in application class. Spring boot is developed for autoconfiguration. Your html or jsp page should be in resources/template or resources/static folder. Please peruse Serving Web Content with Spring MVC , this page can be help you.
