    return "index";
}

@RequestMapping(value = "/new")

The problem is package structure, you not following the standard package structure of spring boot and spring framework. By default spring boot application will only scans the classes annotated with any stereotype from main class and it's sub packages. I would recommend to move all dependency classes under sub packages of main class

com.example.crudbank
  |
  -------------------->CrudBankApplication.java
com.example.crudbank.service
  |
  --------------------->StudentService
com.example.crudbank.controller
  |
  ----------------------> StudentController.java
com.example.crudbank.repository
  |
  -----------------------> StudentRepository.java
com.example.crudbank.domain
  |
  ------------------------>StudentDomain.java
