HQL查詢語句：from Course course where course.name like '%計算機%' order by course.date desc 異常：

subtree 2008-05-06

問題解決了：語句寫錯了！！：
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 }
寫成了：
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);//就這里！真是郁悶
7 } catch (RuntimeException re) {
8 log.error("find all failed", re);
9 throw re;
10 }
11 }
