first, make sure the YourController.java file that has the @Controller and the YourSpringBootFile.java file that has the @SpringBootApplication are in the same package.

If you want your controller to be in a different package outside of YourSpringBootFile.java's package, then follow these instructions = Spring: Run multiple "SpringApplication.Run()" in application main method

There are 2 methods to overcome this

1. Place the bootup application at the start of the package structure and rest all controllers inside it.

   Example :

   package com.spring.boot.app; - You bootup application(i.e. Main Method -SpringApplication.run(App.class, args);)

   You Rest Controller in with the same package structure Example: package com.spring.boot.app.rest;

2. Explicitly define the Controller in the Bootup package.

Method 1 is more cleaner.
