String hql = "SELECT productLine FROM " + ProductLine.class.getSimpleName() 
+ " as productLine " 
+ " join productLine.exchange as exchange " 
+ " where e.exchangeId = :exchangeId ";

将上面hql 的别名exchange 改为e,这个别名不能与前面的join后面的对象命名一样

String hsql = "SELECT productLine FROM " 
+ ProductLine.class.getSimpleName() + " as productLine " 
+ " join productLine.exchange as e " 
+ " where e.exchangeId = :exchangeId ";
