java - 查询异常 : JPA-style positional param was not an integral ordinal

Question

我收到“QueryException:JPA 样式位置参数不是整数序数” 我尝试用其他人解决的方式来解决，例如 org.hibernate.QueryException: JPA-style positional param was not an integral ordinal但还是不行。

我尝试将更改形式 ?1 硬编码为数据库中已有的某些数据，它可以工作，但更改为 ?1 后，它再次出现错误。

--- 硬编码之前(有错误) -- 在存储库中 --

@Query(
    value = "SELECT user_att_workshop.id, user_att_workshop.user_id, user_att_workshop.workshop_att_id, skill.skill_name, user_att_workshop.skill_score " + 
            "FROM user_att_workshop LEFT JOIN skill on user_att_workshop.skill_id = skill.id " + 
            "WHERE user_att_workshop.user_id = ?1 " + 
            "AND user_att_workshop.workshop_att_id = ?2;", 
            nativeQuery = true
)
public List<UserScoreByWorkshopAtt> findUserScoreByUserIdAndWorkshopId(int userId, int workshopId);

-- 服务中 --

public List<UserScoreByWorkshopAtt> findUserScoreByUserIdAndWorkshopIdtest(
    int userId, 
    int workshopId) {

    return 
        userScoreByWorkshopAttRepository.findUserScoreByUserIdAndWorkshopId(
        userId,
        workshopId
    );
}

-- 在 Controller 中 --

List<UserScoreByWorkshopAtt> getUserScooreByUserId(
    @PathVariable("user_id") int userId, 
    @PathVariable("workshop_id") int workshopId) {

    return userScoreByWorkshopAttService.findUserScoreByUserIdAndWorkshopIdtest(
        userId, 
        workshopId
    );

}

--- 硬编码后(可以运行并且没有错误) -- 在存储库中 --

 @Query(value = "SELECT user_att_workshop.id, user_att_workshop.user_id, user_att_workshop.workshop_att_id, skill.skill_name, user_att_workshop.skill_score FROM user_att_workshop LEFT JOIN skill on user_att_workshop.skill_id = skill.id  WHERE user_att_workshop.user_id = 5 AND user_att_workshop.workshop_att_id = 2;", nativeQuery = true)
public List<UserScoreByWorkshopAtt> findUserScoreByUserIdAndWorkshopId();

-- 服务中 --

public List<UserScoreByWorkshopAtt> findUserScoreByUserIdAndWorkshopIdtest() {
    return userScoreByWorkshopAttRepository.findUserScoreByUserIdAndWorkshopId();
}

-- 在 Controller 中 --

List<UserScoreByWorkshopAtt> getUserScooreByUserId(@PathVariable("user_id") int userId,
            @PathVariable("workshop_id") int workshopId) {
        return userScoreByWorkshopAttService.findUserScoreByUserIdAndWorkshopIdtest();
    }

你可以这样写吗:

@Query(
    value = "SELECT user_att_workshop.id, user_att_workshop.user_id, user_att_workshop.workshop_att_id, skill.skill_name, user_att_workshop.skill_score " + 
            "FROM user_att_workshop LEFT JOIN skill on user_att_workshop.skill_id = skill.id " + 
            "WHERE user_att_workshop.user_id = :userId " + 
            "AND user_att_workshop.workshop_att_id = :workshopId;", 
            nativeQuery = true
)
public List<UserScoreByWorkshopAtt> findUserScoreByUserIdAndWorkshopId(@Param("userId")int userId,@Param("workshopId") int workshopId);

或者从查询末尾删除 ';' 并检查是否有空格

@Query(
    value = "SELECT user_att_workshop.id, user_att_workshop.user_id, user_att_workshop.workshop_att_id, skill.skill_name, user_att_workshop.skill_score " + 
            "FROM user_att_workshop LEFT JOIN skill on user_att_workshop.skill_id = skill.id " + 
            "WHERE user_att_workshop.user_id =?1 " + 
            "AND user_att_workshop.workshop_att_id =?2", 
            nativeQuery = true
)
public List<UserScoreByWorkshopAtt> findUserScoreByUserIdAndWorkshopId(int userId, int workshopId);
