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 }
