Как преобразовать application.properties в application.yml в Spring Boot? ⇐ JAVA

[Anonymous]

У меня есть очень простое приложение Spring Boot, есть application.properties, и теперь я хочу перейти к application.yml
Это файл application.yml:
spring:
datasource:
url: jdbc:mysql://localhost:3306/employee_directory
username: student
password: Password123

Итак, я удалил файл application.properties и написал файл application.yml. Если я запущу приложение, я получу следующее исключение:
20:31:22.446 [restartedMain] ERROR org.springframework.boot.SpringApplication - Application run failed

Я думаю, что мне нужно внести другие изменения в свой код, чтобы использовать этот файл application.yml, но я не знаю, что делать?
