org.hibernate.hql.internal.ast.QuerySyntaxException：无效路径：JPQL 自定义查询中的“e.id”

【问题标题】：org.hibernate.hql.internal.ast.QuerySyntaxException: Invalid path: 'e.id' in JPQL custom queryorg.hibernate.hql.internal.ast.QuerySyntaxException：无效路径：JPQL 自定义查询中的“e.id”
【发布时间】：2021-02-22 13:06:41
【问题描述】：

我可以尝试从子查询中获取计数，然后 e.id 显示为无效路径。我的查询很复杂，这就是我陷入困境的原因。如何解决这个错误任何人都知道。

我正在使用带有 jpa 存储库的 spring boot。使用 @Query 注释将查询写入存储库。我尝试使用 UNION 但它不支持 JPA、JPQL 查询。那么使用 JPQL 客户查询的解决方案是什么。我在查询中使用了构造函数，因为我想在每一行中添加 3 种类型的计数。这就是我采用基于构造函数的查询的原因。

1.DTO

package com.techavidus.networkingPhoniex.responseDTO;

import lombok.*;

@ToString
@NoArgsConstructor
@AllArgsConstructor
@Builder
public @Data
class ManageGroupsDTO {

    private Long group_id;

    private String group_name;

    private Long groupTypeId;

    private String groupTypeName;

    private Long countUpcomingEvents;

    private Long countPastEvents;

    private Long countFollows;

    private String groupStates;
}

2.查询

@Repository
public interface GroupsDao extends JpaRepository<Groups, Long> {

   @Query("SELECT new com.techavidus.networkingPhoniex.responseDTO.ManageGroupsDTO(g.group_id, " +
            "g.group_name, gt.group_type_id, gt.name, COUNT(e.id), COUNT(ee.id), COUNT(mgf.id), gs.name) " +
            "FROM Groups g LEFT JOIN MemberFollowGroups mgf LEFT JOIN mgf.groups gf ON gf.group_id = g.group_id " +
            "JOIN g.groupTypes gt LEFT JOIN g.primary_contact_member_id pm " +
            "LEFT JOIN g.secondary_contact_member_id sm LEFT JOIN g.groupStates gs " +
            "WHERE (pm.member_id=:memberId OR sm.member_id=:memberId) IN " +
            "(SELECT e FROM Events e LEFT JOIN e.eventRecurrence er LEFT JOIN e.groups eg ON eg.group_id = g.group_id WHERE e.startDate >=:todayDate) AND " +
            "(SELECT ee FROM Events ee LEFT JOIN ee.eventRecurrence er LEFT JOIN ee.groups eg ON eg.group_id = g.group_id WHERE ee.startDate <:todayDate) " +
            "GROUP BY g.group_id")
    List<ManageGroupsDTO> manageMyGroupList(LocalDate todayDate, Long memberId);
}

3.错误

    【解决方案1】：

    好像你对查询机制有点误解。

    1. 不应该有任何new 调用 - jpa 可以为您组装实体，select new ... 在我看来设计有问题。
    2. 如果你想实现List&lt;ManageGroupsDTO&gt; 的返回类型，JpaRepository&lt;Groups, Long&gt; 看起来是错误的 - 应该有类似 JpaRepository&lt;ManageGroupsDTO, Long&gt; 的东西
    3. 您的实体的@ToString 注释很可能是多余的，因为@Data 注释还包括.toString() 方法创建afaik。

    总结一下，试试这样的：

    @Repository
public interface GroupsDao extends JpaRepository<ManageGroupsDTO, Long> {

   @Query("SELECT g.group_id, g.group_name, gt.group_type_id, gt.name, COUNT(e.id), COUNT(ee.id), COUNT(mgf.id), gs.name " +
            "FROM Groups g LEFT JOIN MemberFollowGroups mgf LEFT JOIN mgf.groups gf ON gf.group_id = g.group_id " +
            "JOIN g.groupTypes gt LEFT JOIN g.primary_contact_member_id pm " +
            "LEFT JOIN g.secondary_contact_member_id sm LEFT JOIN g.groupStates gs " +
            "WHERE (pm.member_id=:memberId OR sm.member_id=:memberId) IN " +
            "(SELECT e FROM Events e LEFT JOIN e.eventRecurrence er LEFT JOIN e.groups eg ON eg.group_id = g.group_id WHERE e.startDate >=:todayDate) AND " +
            "(SELECT ee FROM Events ee LEFT JOIN ee.eventRecurrence er LEFT JOIN ee.groups eg ON eg.group_id = g.group_id WHERE ee.startDate <:todayDate) " +
            "GROUP BY g.group_id")
    List<ManageGroupsDTO> manageMyGroupList(LocalDate todayDate, Long memberId);
}

    如果你没有弄乱结果集的定位，它应该这样修复。

    【讨论】：

    • 但是在 JpaRepository 在这个 repo 中有更多的查询。那么如何像 JpaRepository 一样获取 repo
    • 如果我要进行两个回购，那么他们会给出如下错误： - 不是托管类型：类 com.techavidus.networkingPhoniex.responseDTO.ManageGroupsDTO
    • Not a managed type class 会发生这种错误，因为您忘记使用 @Entity 和相应的表引用注释您的 dto。尝试修复它
    • 我已经拥有此类群组的实体。那么为什么我要为此创建新实体。我希望 3 个字段显式添加到 DTO 中，其他字段可以自动从实体绑定到 DTO。
    • 我怀疑 jpa 真的可以这样工作。如果你有一些嵌套的实体，你必须为每个实体使用单独的存储库接口，ManageGroupsDTO 应该是Groups 实体的字段，通过@OneToOne / @OneToMany 关系，所以要使GroupsDao repo 工作你很可能应该遵循以上步骤。
