I assume that your main class is located in com.testAOP.main; but your controller class is in com.testAOP.controller;.
With that package structure Spring cannot see your controller because it NOT placed in exact package com.testAOP.main; in order to fix that you need to move all your classes into subpackage of your main method class location.
My wild guess would be to move controller from com.testAOP.controller; to com.testAOP.main; or com.testAOP.main.controller; and restart your spring boot application.
As long your components like controller are in subpackage of main method package location, you should be good to go.
