用《开发者突击》里面的初步搭建SSH2的代码，连接sqlserver2005，出现下面提示：
Hibernate: select user0_.ID as ID, user0_.username as username0_, user0_.password as password0_, user0_.email as email0_ from user user0_ where user0_.username=?
WARN - SQL Error: 156, SQLState: S0001
ERROR - 关键字 'user' 附近有语法错误。
2010-12-28 22:22:11 org.apache.catalina.core.StandardWrapperValve invoke
严重: Servlet.service() for servlet default threw exception
com.microsoft.sqlserver.jdbc.SQLServerException: 关键字 'user' 附近有语法错误。
数据库中我建了表 user，属性有id username password email。
applicationContext 代码如下：

请问这是为什么呢？
