У меня есть рабочий код, который перестает работать при изменении версии Spring Boot с 2.0.3.RELEASE на 2.1.0.M4
Ошибка:
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

APPLICATION FAILED TO START

Description:
The bean 'dataSource', defined in BeanDefinition defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class] and overriding is disabled.
Action:
Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
Aсвоего рода похожий вопрос ( Проблема при смене версии Spring Boot с 2.0.3.RELEASE на 2.1.0.BUILD-SNAPSHOT ) уже задавалась, но не был дан правильный ответ.

Прогресс
С весны 2.1.0 Примечания к выпуску M1 (https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.1.0-M1-Release-Notes) Я вижу, что переопределение бина было отключено.
Ошибка исчезает, когда ядобавить свойство allow-bean-definition-overriding: true в мой файл application.yml, но затем я получаю следующую ошибку:
