Я пытаюсь заставить API работать в springboot, однако, когда я ввожу запрос: http://localhost:8080/employee/all Я получаю такой результат:

 "timestamp": "2021-10-10T20:05:58.353 00:00",
    "status": 404,
    "error": "Not Found",
    "path": "/employee/all"
 

это классическая служба с моделью, службой, хранилищем, картографом и исключением, если нет сотрудника, используемая база данных находится в sql с объектами, представленными ниже

Проблема в EmployeeMapper том, что .

Это то, что вы сделали в своем коде:

 @RequestMapping
@RestController("/employee")
 

Если вы измените его на:

 @RequestMapping("/employee")
@RestController
 

Это должно быть исправлено.
