问题解决了：语句写错了！！：

 1    public List findByHql(String hql){    
 2          log.debug("finding all Course instances");     
 3          try {
 4             String queryString = "from Course course " +hql+" ";
 5             System.out.println("\n\n"+queryString+"\n\n");
 6             return getHibernateTemplate().find(queryString);
 7          } catch (RuntimeException re) {
 8             log.error("find all failed", re);
 9             throw re;
10          } 
11  }

写成了：

 1  public List findByHql(String hql){
 2       log.debug("finding all Course instances");
 3       try {
 4           String queryString = "from Course course " +hql+" ";
 5           System.out.println("\n\n"+queryString+"\n\n");
 6           return getHibernateTemplate().find(hql);//就这里！真是郁闷
 7        } catch (RuntimeException re) {
 8           log.error("find all failed", re);
 9           throw re;
10        } 
11  }
