java.sql.SQLException: Access denied for user ''@'localhost' (using password: No)

出错原因:

刚在学hiberbate4,把持久层从纯粹的jdbc改为hiberbate 出现的错误。(原来的是直接读取properties)

解决方法就是在hibernate.cfg.xml加上最后两行(当然其他的也必不可少)

1 <property name="connection.url">jdbc:mysql://localhost:3306/sm</property>
2     <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
3       <property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>
4     <property name="connection.username">root</property>
5     <property name="connection.password">genji</property>
