No suitable driver found for jdbc:mysql://localhost:3306/hibernate

Struts Problem Report

Struts has detected an unhandled exception:

Messages:	No suitable driver found for jdbc:mysql://localhost:3306/hibernate_basic Cannot open connection Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.JDBCConnectionException: Cannot open connection

调试了半天，在@test程序中都能连接数据库正确

后来在 hibernate.cfg.xml中加入

<property name="connection.driver_class">com.mysql.jdbc.Driver</property>

就正常运行了
