Copyright 2004-2011 Aspose Pty Ltd. 接口IUserDAO的代码如下： package org.easybooks.bookstore.dao; import org.easybooks.bookstore.vo.User; public interface IUserDAO { public User validateUser(String username,String password); } 然后在src下创建org.easybooks.bookstore.dao.impl包，在包中创建类UserDAO，此类继承自BaseDAO，并且实现了IUserDAO接口中的validateUser()方法。 修改applicationContext.xml文件，代码所示。 Evaluation only.
