JPA查询未返回与日志查询相同的结果

Question

我有一个简单的JPA查询，它像这样使用（ProcessDetailCategory是一个字符串值枚举）：

List<ProcessDetail> currentProcessDetails = processDetailRepository.findByProcessIdAndProcessDetailCategoryAndProcessFileNotNull(process.getId(), ProcessDetailCategory.LIST_ELEMENT);

我已启用查询日志记录：

logging.level.org.hibernate.SQL: DEBUG
logging.level.org.hibernate.type.descriptor.sql.BasicBinder: TRACE
spring.jpa.show-sql: true

日志说

Hibernate: select processdet0_.id as id1_66_, processdet0_.process_id as process_4_66_, processdet0_.process_detail_category as process_2_66_, processdet0_.process_file_id as process_3_66_, processdet0_.url_link as url_link5_66_ from process_details processdet0_ where processdet0_.process_id=? and processdet0_.process_detail_category=? and (processdet0_.process_file_id is not null)

格式化：

HIBERNATE:

SELECT processdet0_.id                      AS id1_66_,
   processdet0_.process_id              AS process_4_66_,
   processdet0_.process_detail_category AS process_2_66_,
   processdet0_.process_file_id         AS process_3_66_,
   processdet0_.url_link                AS url_link5_66_
FROM   process_details processdet0_
WHERE  processdet0_.process_id = ?
   AND processdet0_.process_detail_category = ?
   AND ( processdet0_.process_file_id IS NOT NULL )  

当我在数据库上手动运行此查询时，我得到结果，但是JPA查询未返回任何结果。不，我不是在查询错误的数据库，其他一切都很好。
