spring - Spring：无法配置数据源：未指定“url”属性，无法配置嵌入式数据源

Question

我的 application.properties 是：

spring.datasource.url=jdbc:mysql://localhost:3306/bdd_disc?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=MP18711922
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELEC 1

# Show or not log for each sql query
spring.jpa.show-sql = true

# Hibernate ddl auto (create, create-drop, update)
spring.jpa.hibernate.ddl-auto = update

# Naming strategy
spring.jpa.hibernate.naming-strategy =   org.hibernate.cfg.ImprovedNamingStrategy

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

当我进行 maven Build 并尝试运行主 SpringBoot 类时，我收到以下消息：

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

好的，我通过添加发现了问题：

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

在 application.properties 中。

对不起...
