hibernate中类not mapped问题

Question

spring项目中，用到hibernate mapping。后台写完之后junit test可以跑通，数据库可以存取数据，但是页面数据传过来之后，hql报错。已经仔细检查过hql中是查询的是类名还是表名以及各项配置，hpl中查询的是map过的类名。单元测试跑得通，所以xml配置应该也没错。但是页面存取数据的时候会报错。仔细检查过hql的大小写，全半角以及空格是否为中文空格，依然不能解决问题。希望各路高人给指条明路，感激不尽。。

报错内容：[code=text]
Caused by: org.hibernate.hql.ast.QuerySyntaxException: User is not mapped [from User where userName=?]
[/code]

具体的配置如下。

实体类：[code=java]
package com.huatek.cloud.usercenter.entity;

import com.huatek.framework.entity.FwAccount;

public class User extends FwAccount{

private static final long serialVersionUID = 6736542524764495567L;

private String seqNum;                              //数据的序列号，数据库中主键（id）。由于BaseServiceImpl中存在id字段，故重命名

private String userName;                            //用户名字段。如果注册方式为邮箱则它的值为email值；注册方式为手机则值为cellphone值

private String email;                               //用户的邮箱地址字段

private String cellphone;                           //用户的手机号字段

private int regType;                                //用户的注册类型字段

private String password;                            //用户的密码字段

private int activated;                          //用户的“是否激活”字段

private String validateCode;                        //用户的激活码字段

private java.sql.Timestamp registerTime;                            //用户的注册时间字段


//getter、setter方法略

}
[/code]

类与表的映射文件：User.hbm.xml
[code=text]

import 实体类所在的package;

配置映射文件：application-base.xml
[code=text]
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

    <property name="mappingLocations">
        <list>
            <!-- base frame -->

            </entry>
        </map>
    </property>
</bean>

[/code]

服务层中的实现方法，实际是就是判断userName是否已经存在库中以实现判断用户名重复：
[code=java]
@Override
public boolean cmpUserName(int regType, String userName) {

    String hql = "from User where userName=?";
    @SuppressWarnings("unchecked")
    List<User> resultUser = hibernateTemplate.find(hql,userName);  //每次debug单步跟进到这里报错

    if (resultUser.isEmpty())
         return userNameNotDup;
     else
         return userNameDup;
}

[/code]
