我正在开发一个已经与hibernate一起使用的基本应用程序，并希望添加spring JPA功能以使其更简单 .

当我用hibernate测试时，我能够毫无问题地连接到mysql数据库 . 但是当我从spring boot测试应用程序时，数据库访问失败 . 我在hibernate.cfg.xml和application.properties中都给出了相同的凭据 . 但不确定为什么 spring 访问失败 .

我尝试授予用户权限 . 但仍然没有工作 .

GRANT ALL PRIVILEGES ON *.* TO 'logesh'@'localhost' WITH GRANT OPTION;

的hibernate.cfg.xml

com.mysql.cj.jdbc.Driver

jdbc:mysql://localhost:3306/devops

logesh

logesh

org.hibernate.dialect.MySQL5Dialect

create

true

application.properties

spring.datasource.url=jdbc:mysql://localhost:3306/devops

spring.datasource.username=logesh

spring.datasource.password=logesh

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

spring.jpa.database-platform = org.hibernate.dialect.MySQL5Dialect

spring.jpa.generate-ddl=true

spring.jpa.hibernate.ddl-auto = create

以下是我在 Spring 季启动时遇到的错误：

java.sql.SQLException: Access denied for user 'logesh'@'localhost' (using password: YES)

以下是MySQL常规日志，我们可以看到spring boot登录失败 . 随后在尝试使用hibernate时，它可以登录 .

我被困在这里，任何帮助将不胜感激 .

我只能执行第三个命令，我已经尝试过了 .
