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spring JPA功能以使其更简单。
当我使用休眠进行测试时，我可以无任何问题地连接到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中都提供了相同的凭据。但不确定为什么弹簧访问会失败。
我尝试将特权授予用户。但仍然无法正常工作。

以下是我在春季靴中遇到的错误：

以下是MySQL常规日志，在该日志中我们可以看到Spring Boot登录失败。随后，当尝试使用休眠模式时，便可以登录。

我只能执行已经尝试过的第三条命令。
编辑： 这个问题不是Java JDBC Access denied for user的重复，因为我在发布这个问题之前已经尝试了所有推荐的解决方案。
答案 0 :(得分：1)
用户名后面似乎有一些空格。
您能否检查属性文件中用户名或密码后面是否有空格。如果logesh后面有空格，请将其删除。
答案 1 :(得分：0)
您正在使用哪个版本的Spring Boot和MySQL？我创建了一个最小的应用程序，并且运行正常（源代码为https://github.com/behrangsa/stackoverflow-q53692999）。
还要注意，MySQL的当前JDBC驱动程序类名称为com.mysql.cj.jdbc.Driver。
