Сбой соединения с загрузочной базой данных Intellij Spring с java.io.FileNotFoundException

/ 03 октября 2019

Я очень впервые использую intellij и весеннюю загрузку. (До вчерашнего дня не разрабатывал веб) Я устал делать простой веб-сайт по заказу книги. Но когда мне не удается подключиться к базе данных MySQL.

Сначала я увидел, что «Не удалось настроить источник данных: не указан атрибут« url »и невозможно настроить встроенный источник данных». Поэтому я написал коды в application.properties и сделал класс DatabaseConfiguration. После этого у меня не получилось сообщение о том, что «вложенное исключение - это java.io.FileNotFoundException: ресурс пути к классу [application.properties] не может быть открыт, потому что он не существует», а также предупреждающее сообщение о «Предупреждение: невозможно создать модуль: board. Основная, связанная конфигурация gradle не найдена. Пожалуйста, повторно импортируйте проект Gradle и попробуйте снова. '(Я уже пробовал щелкнуть gradel-> re-import и получил диалоговое окно' Модули IDE ниже были удалены Gradle import: board.test board.main. Вы можете открыть диалог, чтобывыберите те, которые вам нужно восстановить. «Что мне делать дальше?)

Я думаю, что у меня есть несколько проблем здесь. Не могли бы вы помочь мне с этим? Спасибо. Да, и я попытался набрать 'src / main / resources / application.properties и не работал)
