java - Hibernate 5.2后如何使用 `setResultTransformer`？

Question

我想用 query.setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP)获取 List<Map> .但我有一个异常(exception):

java.lang.NoSuchMethodError: org.hibernate.query.Query.setResultTransformer(Lorg/hibernate/transform/ResultTransformer;)Lorg/hibernate/Query;

我找不到 org.hibernate.query.Query 的实现类. 方法setResultTransformer在 org.hibernate.Query .

为什么不推荐使用 org.hibernate.Query？

Answer 1

The ResultTransformer comes with a legacy definition which is not following the Functional Interface syntax. Hence, we cannot use a lambda in this example. Hibernate 6.0 aims to overcome this issue, so that’s why the Hibernate ORM 5.2 ResultTransformer is deprecated. Nevertheless, an alternative will be provided, so the concept we are discussing in this article is going to stand still even in Hibernate 6.
