两天以来我一直陷入这个问题。谁能告诉我这个错误的原因是什么？

【问题讨论】：

“访问被拒绝”甚至在查看代码之前就解释了您的整个问题。

标签： java mysql spring hibernate

【解决方案1】：

我有 95% 的判断是您的凭据不正确，或者您不允许从您的 IP 使用该用途登录。

登录名 '"root"' 看起来不正确。这不应该是 " 围绕根。它应该看起来像这样：'root'@'localhost'

【讨论】：

我确信凭据是正确的。代码肯定有其他一些问题。
见我回答的第二部分。这就是你的问题所在。 '"root"' 不是 'root'
我已经将数据库用户名传递为这行有问题吗？
我不知道...我只能说：“ ”不应该在那里。你确定这是使用的价值吗？
我想说的是：也许“根”来自不同的文件。

【解决方案2】：

我认为您需要从 localhost 授予对 root 的访问权限，请查看 this

【讨论】：

【解决方案3】：

我 99% 确定您的凭据有误，但为了确定，请按照以下步骤缩小您的问题范围 -

以 root 身份尝试以下命令。

mysql -u root -proot

如果你不能连接到 MySQL，你肯定有凭据错误。
如果您能够以 root 身份访问 MySQL，请退出 root 并执行从你的命令行再次命令（没有root权限）。

mysql -u root -proot

如果您无法连接到 MySQL，则表示您没有从登录的用户帐户访问以连接到 MySQL。

要纠正此问题，请按照以下步骤操作 - https://askubuntu.com/questions/766334/cant-login-as-mysql-user-root-from-normal-user-account-in-ubuntu-16-04
执行您的代码，如果问题仍然存在，请恢复。
