bottlauncherapp.java

package com.sonic.applauncher;  import org.springframework.boot.springapplication; import org.springframework.boot.autoconfigure.springbootapplication;  @springbootapplication public class bootlauncher {     public static void main(string[] args) throws exception {         springapplication.run(bootlauncher.class, args);     }  } 

pagecontroller.java

package com.sonic.controller;  import org.springframework.web.bind.annotation.requestmapping; import org.springframework.web.bind.annotation.restcontroller;  @restcontroller public class pagecontroller {     @requestmapping("/index")     public string index(){         return "home";     } } 

even had same issue.just annotate @componentscan("com.sonic").

this should work!!
