acegi的配置（省略前面的，只把sql写出来了）：
<bean id= "userDetailsService "
class= "org.acegisecurity.userdetails.jdbc.JdbcDaoImpl ">
<property name= "dataSource "> <ref bean= "dataSource "/> </property>
<property name= "usersByUsernameQuery ">
<value>
select name,passwd from users where name = ?
</value>
</property>
</bean>

问题：
1。这个越界怎么解释呢？
2。就算失败，怎么转到404。jsp呢，我在authenticationProcessingFilter里面定义了authenticationFailureUrl的啊？
------解决方法--------------------------------------------------------
1.是因为你项目中使用的数据库登录用户没有操作users这个表的权限。
2.不知道authenticationProcessingFilter这个里面你是怎么处理的，但是你要控制错误页面的话，可以在web.xml设置error-page:
<error-page>
<error-code> 404 </error-code>
<location> /*.jsp </location>
</error-page>
