我正在尝试做项目解释在这里输入链接描述（代码在页面末尾），但是当我运行它时出现错误：

我认为错误可能与 CLASSPATH 相关，但我完全不确定。此错误的原因可能是什么，我该如何解决？

这个错误的根本原因解释得很清楚：

SELECT command denied to user 'sqluser'@'localhost' for table 'COMMENTS'

只要确保创建一个名为的 mysql 用户sqluser并授予它对'COMMENTS'表的适当权限即可。

又快又脏：GRANT ALL PRIVILEGES ON your_db_name.* TO 'sqluser'@localhost IDENTIFIED BY 'sqluserpw';
