Hibernate可以连接到mysql，但SpringJPA不能

mysql spring hibernate spring-boot

Hibernate可以连接到mysql，但SpringJPA不能,mysql,spring,hibernate,spring-boot,Mysql,Spring,Hibernate,Spring Boot,我正在开发一个已经可以与hibernate一起使用的基本应用程序，并希望添加SpringJPA功能以使其更加简单 当我使用hibernate进行测试时，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中提供了相同的凭据。但不确定spring访问失败的原因 我尝试将特权授予该用户。但仍然不起作用 GRANT ALL PRIVILEGES ON *.*

当我使用hibernate进行测试时，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中提供了相同的凭据。但不确定spring访问失败的原因

我尝试将特权授予该用户。但仍然不起作用

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

    <hibernate-configuration>
    <session-factory>
    <property name="hibernate.connection.driver_class">com.mysql.cj.jdbc.Driver</property>

    <property name="hibernate.show_sql">true</property>
以下是我在spring boot中遇到的错误：

我只能执行第三个命令，我已经试过了

编辑：
这个问题不是重复的，因为在发布这个问题之前，我已经尝试了所有推荐的解决方案

您使用的是哪个版本的Spring Boot和MySQL？我创建了一个最小的应用程序，它工作得很好（这里的源代码：）

还要注意，MySQL的当前JDBC驱动程序类名是
com.MySQL.cj.JDBC.driver

运行MySQL 创建数据库和用户 
pom.xml
运行应用程序：
