</persistence>

application.properties

spring.datasource.url = jdbc:mysql://localhost:3306/myDB?useSSL=false

# Username and password
spring.datasource.username = root
spring.datasource.password = root    

错误

Exception in thread "main" org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]

Caused by: java.sql.SQLException: Access denied for user ''@'localhost' (using password: NO)

Answer 1

尝试删除=、用户名和密码之间的空格。

spring.datasource.username=root
spring.datasource.password=root
