поэтому я следовал этому руководству по созданию небольшого веб-сайта: https://medium.com/@alexandre.therrien3 ... 413e661db5
Я использовал mssql в качестве базы данных, но кажется, что у Spring возникают некоторые проблемы с подключением к нему в моей Файл DataSourceConfig.java:
Импорт org.springframework.boot.autoconfigure.jdbc не может быть разрешен
Сначала при импорте было еще несколько ошибок в VS Code, поэтому я выполнил установку mvn:
mvn install:install-file "-Dfile=sqljdbc4.jar" "-DgroupId=com.microsoft.sqlserver" -DartifactId=sqljdbc4 "-Dversion=4.0" -Dpackaging=jar
