用ssh做了一个登录 出现下面的问题了
org.springframework.orm.hibernate3.HibernateQueryException: t_user is not mapped [from t_user where name=? and password=?]; nested exception is org.hibernate.hql.ast.QuerySyntaxException: t_user is not mapped [from t_user where name=? and password=?]

LoginAction里的代码：

public String execute() {
User user = new User();
user.getName();
user.getPassword();
//System.out.println(user.getId()+"1");
if (userService.login(user)) {

return "YES";
}
//System.out.println(user.getName()+"****"+user.getPassword());
return "NO";
}
LoginDAOImp里的代码：


public boolean getAllUser(User user) {
System.out.println(user.getName()+"3");


String hql = "from t_user where name=? and password=?";
Object []obj ={user.getName(),user.getPassword()};

List list = super.getHibernateTemplate().find(hql);

if(list.size()>0){
System.out.println("成功！");
return true;
}else{
return false;
}
}

------解决方案--------------------
很明显t_user没有和数据库映射好，配置文件没配？还是粗心没配好？
用注解的话，类上加个@Entity,主键上加个@Id 就ok 了
org.springframework.orm.hibernate3.HibernateQueryException: t_user is not mapped [from t_user where name=? and password=?]; nested exception is org.hibernate.hql.ast.QuerySyntaxException: t_user is not mapped [from t_user where name=? and password=?]
------解决方案--------------------
String hql = "from t_user where name=? and password=?";
这是sql,不是hql
HQL是这样的
String hql = "from User user where user.name=? and user.password=?";
------解决方案--------------------
应该是hql语句，hibernate是对对象操作，
------解决方案--------------------
映射 存在问题 表和映射bean不对应！ 检查你的bean
------解决方案--------------------
数据库的表存在映射的问题。
