Legacystyle query parameters (`?`) are no longer supported; use JPAstyle ordinal parameters (e.g., `?1`) instead

<dependency>
	<groupId>org.hibernate</groupId>
	<artifactId>hibernate-core</artifactId>
	<version>5.4.8.Final</version>
</dependency>

• 错误方式

String hql = "from Teacher t where  t.teacherName = ? and t.teacherPwd = ?";
Query query = session.createQuery(hql);
query.setParameter(0, username);
query.setParameter(1, password);

报错
Legacy-style query parameters (`?`) are no longer supported; use JPA-style ordinal parameters (e.g., `?1`) instead
不再支持遗留样式的查询参数(' ? ');而是使用jpa风格的序数参数(例如，' ?1 ')

• 解决

String hql = "from Teacher t where  t.teacherName = ?1 and t.teacherPwd = ?2";
Query query = session.createQuery(hql);
query.setParameter(1, username);
query.setParameter(2, password);
