我在netbeans中为一个项目（java web应用程序）连接了一个MySQL数据库。我创建了具有正确登录详细信息的MySQL服务器，并创建了一个数据库。我将我的数据库连接到项目，但是当我运行应用程序时，它在浏览器中显示错误：
type Exception report message Internal Server Error description The server encountered an internal error that prevented it from fulfilling this request. exception javax.servlet.ServletException: java.sql.SQLException: Access denied for user 'User'@'localhost' (using password: YES) root cause java.sql.SQLException: Access denied for user 'User'@'localhost' (using password: YES) note The full stack traces of the exception and its root causes are available in the GlassFish Server Open Source Edition 4.1.1 logs.
日志文件中的条目是：

我在其他一些形式中提到的几种方式感到厌倦但没有使用。
答案 0 :(得分：0)
您没有正确创建用户getLocation();
var rowId=timesheetGrid.uid();
var pos = timesheetGrid.getRowsNum();
timesheetGrid.addRow(rowId,["","","","<?php echo $ActiveWeek; ?>","","","","","","","","","","",Loc],0); //adds a new row with pre filled data
timesheetGrid.selectCell(rowId,0,false,true,true); // Focus on the new row
。

我找到了解决方案，当我使用sql语句获取授权权限时，我使用了
'user@%'，因为它无效。正确的sql语句是：
GRANT ALL PRIVILEGES ON dbname.* TO 'User'@'localhost' IDENTIFIED BY 'Pass' WITH GRANT OPTION;
