org.hibernate.dialect.MySQLInnoDBDDialect
知道了不是少包，而是你的hibernate.cfg.xml文件中将数据库方言配置错了，
应该是MySQLInnoDBDialect 不是MySQLInnoDBDDialect
后者多了一个D啊，你看看你的配置文件

HQL中不能用*啊 你既然用u对User取了别名，改成select count(u) from User u where u.username = :username就可以了

MySQL with InnoDB（5） org.hibernate.dialect.MySQLInnoDBDialect
MySQL5 with InnoDB org.hibernate.dialect.MySQL5InnoDBDialect
MySQL with MyISAM org.hibernate.dialect.MySQLMyISAMDialect
