hibernate中hql的 in用法

删除表PatrolJobContent中的部分deviceId，deviceId保存在List<String>deviceIds中

我们可以通过遍历List，一条一条的删除记录：

public void deleteDeviceIds (List<String>deviceIds){
		String hql ="delete from PatrolJobContent as p where p.PatrolDevice.uuid= ? ";
		for(String uuid : deviceIds){
			Query q =this.createQuery(hql, new Object[]{uuid});
			q.executeUpdate();
			
		//	this.execute(hql, new Object[]{uuid});
		}
	}

现在我们根据hql的关键字 in，来进行删除操作

public void deleteDeviceIds(final List<String> deviceIds) {
		this.getHibernateTemplate().execute(new HibernateCallback<Object>() {

			@Override
			public Object doInHibernate(Session session) throws HibernateException {
				session.createQuery("delete from PatrolJobContent as p where p.PatrolDevice.uuid in (:deviceIds) ").setParameterList("deviceIds", deviceIds);
				return null;
			}
		});

	}

即可。
