无法使用JPA查询检索结果

Question

我试图构建一个Spring Boot REST API，从MySQL DB中获取数据。这是我在Spring Boot REST API应用程序的存储库代码中定义的JPA查询方法：

public interface WeekRepository extends CrudRepository<Week, UUID> {
           Iterable<Week> findByOriginId(UUID originId);
}

这是我要查询的表的详细信息：

CREATE TABLE `week` 
  ( 
     `id`        DOUBLE NOT NULL auto_increment, 
     `due_date`  TIMESTAMP NOT NULL, 
     `origin_id` BINARY(36) DEFAULT NULL, 
     `status`    VARCHAR(36) DEFAULT NULL, 
     PRIMARY KEY (`id`) 
  )  

SELECT week0_.id        AS id1_3_, 
       week0_.due_date  AS due_date2_3_, 
       week0_.origin_id AS origin_i3_3_, 
       week0_.status    AS status4_3_ 
FROM   week week0_ 
WHERE  week0_.origin_id = ?; 

2021-01-15 00:44:05.916 TRACE 44612 --- [nio-8082-exec-2] o.h.type.descriptor.sql.BasicBinder      : binding parameter [1] as [VARCHAR] - [49ee49da-8e6e-45f0-a0ea-e63205077870]

Answer 1

请在originId属性中添加以下注释，以使hibernate添加必要的转换。mysql的UUID道具似乎有些问题

@Column(name = "origin_id")
@Type(type="uuid-char")
private UUID originId;
