我可以在 JpaRepository nativeQuery 中使用枚举参数吗? [英] Can I use enum parameter into JpaRepository nativeQuery?

问题描述

实体看起来像这样:

@Getter
@Setter
@Entity
public class Application {
@Id
private Long id;
@Enumerated(EnumType.STRING)
private ApplicationStatus status;
}

代码是这样工作的:

public interface ApplicationRepository extends JpaRepository<Application, Long> {
@Query("SELECT app FROM #{#entityName} AS app WHERE app.status LIKE :status")
List<Application> find(@Param("status") ApplicationStatus status);

但与 nativeQuery 相同的片段 - 没有:

But the same snippet with nativeQuery - doesn't:

@Query(value = "SELECT app.* FROM application AS app WHERE app.status LIKE :status", nativeQuery = true)
List<Application> findNative(@Param("status") ApplicationStatus status);
}

而且我没有任何异常，只是空列表.

And I don`t have any exception, just empty list.

我该如何解决这个问题?是否可以将 enum 与 nativeQuery 一起使用?

How can I fix this? Is it possible to use enum with nativeQuery?

P.S 我可以将 String 传递给方法而不是 ApplicationStatus 但也许还有另一种选择?

P.S I can pass String into method instead of ApplicationStatus but maybe there are another option?

推荐答案

Following similar question 和href="https://stackoverflow.com/a/54650103/906265">其中一个答案指向Spring 表达式语言 (SpEL) 您可以使用:

Following similar question with similar requirement and one of the answers pointing to Spring Expression Language (SpEL) you could use:

public interface ApplicationRepository extends JpaRepository<Application, Long> {
    @Query(nativeQuery = true, value = "SELECT app FROM #{#entityName} AS app WHERE app.status=:#{#status.name()}")
    List<Application> find(@Param("status") ApplicationStatus status);
}

以上重要部分是app.status=:#{#status.name()}
