hibernate查詢語句hql中的占位符?參數與命名參數：name設值方式搞混

先貼出異常

 Struts has detected an unhandled exception:
Messages: 	
Position beyond number of declared ordinal parameters. Remember that ordinal parameters are 1-based! Position: 1
File: 	org/hibernate/engine/query/spi/ParameterMetadata.java

Stacktraces
org.hibernate.QueryParameterException: Position beyond number of declared ordinal parameters. Remember that ordinal parameters are 1-based! Position: 1

 代碼：

//定義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中設值
Query query = sessionFactory.getCurrentSession().createQuery(hql);
		for (int i = 0; i < objects.length; i++) {
			query.setParameter(i, objects[i]);
		}

 

原因：

異常上說占位符索引越界(溢出)，原因是我定義的hql中根本沒有占位符“?”，我用的是命名參數，應該通過setString(paraName,paraValue)或者setParameter(paraName,paraValue)的方式來設值，我卻用setParameter(int arg0, Object arg1)來設值，所以就報錯了！

 

解決辦法：

對於我這個，我通過吧:queryArgs全部替換成？的方式。
