JBoss Web/7.0.13.Final

提前谢谢

Answer 1

根本原因是：

java.sql.SQLException: Access denied for user 'root'@'localhost'

请确保您可以使用mysql客户端连接到您的mysql数据库，例如Workbench。

Answer 2

在该堆栈跟踪中，您的密钥应为

Access denied for user 'root'@'localhost' (using password: YES)

您似乎没有适当的凭据来访问您的mysql数据库。

检查您输入的用户名和密码是否正确。

同时检查mysql是否绑定到0.0.0.0地址，否则无法使用计算机的物理IP地址连接到它。
