将 Spring Boot 2.5.2 升级到 2.6.3 会破坏所有基于投影的 JPA 查询

Upgrading Spring Boot 2.5.2 to 2.6.3 breaks all projection based JPA queries

当我尝试将应用程序的 Spring 启动从 2.5.2 升级到 2.6.3 时,所有基于投影的 JpaRepository 查询都无法生成,如下所示:

方法看起来像:

Optional<SomeProjection> getProjectionByIdAndField(String id, String field);

投影是基于界面的,如下所示:

public interface SomeProjection {
  Long getSomething();
}

如果我用@Query 手动编写查询,它会移动到下一个投影。有什么方法可以解决这个问题,而不必为所有基于投影的 JPA 方法手动编写查询吗?

我在这里找不到任何关于这个问题的提及: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.6-Release-Notes#upgrading-from-spring-boot-25

我发现他们在以下方面提到了对预测的一些改进: https://github.com/spring-projects/spring-data-commons/wiki/Release-Train-2021.1-%28Q%29-Release-Notes#jdbc.projections

但与破坏旧版本无关。

这是一个bug introduced in Spring Data JPA 2.6.1。升级到 Spring Boot 2.6.4 以获得包含修复程序的 Spring Data JPA 版本。
