相關代碼如下：

/**(非 Javadoc)* <p>Description(描述):根據員工的姓名查詢員工信息 </p>* <p>Title: queryInfoByName</p>* @param name* @return* @see org.dao.IEmpDao#queryInfoByName(java.lang.String)*/@Overridepublic Emp queryInfoByName(String name) {Emp emp = null;String hql = " from Emp where ename = ?";Session session = this.getSession();List<Emp> empList = session.createQuery(hql).setParameter(1, name).list();if(empList.size()!=0){emp = empList.get(0);}return emp;}

注意看這里：

setParameter(1, name)

很明顯，這個地方的1應該改成0，但是我原來就是0來著，網上有人說要改成1.。。。。。。我以為我記錯了？想著反正也是個錯，何不試試呢。于是就二了起來試了試，也許之前越界是其他的原因，改到后面居然忘了到底改哪里了，于是乎把1重新改成了0之后終于可以用了。

setParameter(1, name)

正確詳細代碼如下：

/**(非 Javadoc)* <p>Description(描述):根據員工的姓名查詢員工信息 </p>* <p>Title: queryInfoByName</p>* @param name* @return* @see org.dao.IEmpDao#queryInfoByName(java.lang.String)*/@Overridepublic Emp queryInfoByName(String name) {Emp emp = null;String hql = " from Emp where ename = ?";Session session = this.getSession();List<Emp> empList = session.createQuery(hql).setParameter(0, name).list();if(empList.size()!=0){emp = empList.get(0);}return emp;}

總結
