Hibernate查询语句异常

org.hibernate.hql.ast.QuerySyntaxException: unexpected token: class near line 1, column 6 [from class cn.itcast.oa.domain.Department]

   错误是因为：hql语句有问题
        @Override
public Collection<T> getAllEntry() {
return this.hibernateTemplate.find("from " + this.clazz);
}
   应该为：
        @Override
public Collection<T> getAllEntry() {
return this.hibernateTemplate.find("from " + this.clazz.getName());
}
