org.hibernate.QueryParameterException: Position beyond number of declared ordinal parameters. Remember that ordinal parameters are 1-based! Position: 1
代码：
//定义hql
String hql = "from Book book where "
+ "book.bookType like :queryArgs or "
+ "book .bookNum like :queryArgs or "
+ "book.bookName like :queryArgs or "
+ "book.bookAuthor like :queryArgs "
+ "order by book.bookType, book .bookNum, book.bookAuthor, book.bookName";
//dao中设值
Query query = sessionFactory.getCurrentSession().createQuery(hql);
for (int i = 0; i < objects.length; i++) {
query.setParameter(i, objects[i]);
}
原因：
异常上说占位符索引越界(溢出)，原因是我定义的hql中根本没有占位符“?”，我用的是命名参数，应该通过setString(paraName,paraValue)或者setParameter(paraName,paraValue)的方式来设值，我却用setParameter(int arg0, Object arg1)来设值，所以就报错了！
解决办法：
对于我这个，我通过吧:queryArgs全部替换成？的方式。
hibernate查询语句hql中的占位符?参数与命名参数：name设值方式搞混
