我从Spring Boot(Data)3.1.5升级到3.2.0.
我在存储库中的几个查询现在在验证阶段的应用程序启动时抛出异常:
Caused by: Cannot compare left expression of type 'java.lang.Object' with right expression of type 'java.lang.Long'.
例如:
@Query(value = "SELECT new com.my.service.crud.ReferencedObject(p.id, p.name, r.name) FROM MyEntityA p join MyEntityB r on (p.aId = r.id) WHERE " +
" p.aId = :projectId and exists (select id from EntityC where cId = p.id and dTypeId = :uutId)")
List<ReferencedObject> findReferencesToUtilType(@Param("projectId") Long projectId, @Param("uutId") Long utilTypeId);
这个(匿名的)代码在3.1.5中工作得很好，并返回一个ReferencedObject列表.
我甚至在返回Optional<Entity>和findByIdAndOtherAttr(...)的查找器上遇到错误.
根本原因是

我找到了这个https://discourse.hibernate.org/t/upgrade-to-6-3-rc1-cannot-compare-left-expression-of-type-java-sql-timestamp-with-right-expression-of-type-com-model-entity-impl-user/8034/5 冬眠团队的成员说，这是在比较苹果和橙子.
有没有人有迁移指南的链接？
我必须做什么才能让我的查询再次工作？
在Spring Boot 3.2.0的发行说明中，我只发现了一条提示:"不推荐使用的特性现在已经被取消发布了".
谢谢你的任何提示！
