Question

我正在尝试解释enter link description here项目（代码位于页面末尾），但是当我运行它时会出现错误：

Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: SELECT command denied to user 'sqluser'@'localhost' for table 'COMMENTS'

我认为错误可能与CLASSPATH有关，但我根本不确定。可能是造成这个错误的原因是什么，我该如何解决？

很明显地解释了这个错误的根本原因：

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

请务必创建一个名为sqluser的mysql用户，并在'COMMENTS'表上授予其相应的权限。

快速而肮脏：GRANT ALL PRIVILEGES ON your_db_name.* TO 'sqluser'@localhost IDENTIFIED BY 'sqluserpw';
