运行报这个错，该怎么解决？

Question

org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Access denied for user 'newsu'@'localhost' (using password: YES))

Answer 1

你这个应该是没有设置localhost用户的密码
设置方式为GRANT ALL PRIVILEGES ON newsu.* TO 'xx'@'%' IDENTIFIED BY 'xx' WITH GRANT OPTION;

如果dbcp觉得复杂的话，可以用我写的jdbc，简单、易用
