我的代码无法注入以下存储库。根据堆栈跟踪，我的 HQL 语法似乎无效，但我不确定我做错了什么。

@Repository
 public interface JobSetRepository extends JpaRepository<JobSetEntity, Integer> {
    @Modifying
    @Transactional
    @Query("UPDATE JobSetEntity SET workstation = :workstation, workflowProcess = :workstation.workflowProcess WHERE id = :jobSet.id")
    public Boolean updateWorkstation(@Param("jobSet") JobSetEntity jobSet, @Param("workstation") Workstation workstation);

    @Modifying
    @Transactional
    @Query("UPDATE JobSetEntity SET workflowProcess = :workflowProcess, workstation = null WHERE id = :jobSet.id")
    public Boolean updateWorkflowProcess(@Param("jobSet") JobSetEntity jobSet, @Param("workflowProcess") WorkflowProcess workflowProcess);
}

堆栈跟踪：

更新：我也收到此查询的此错误：

@Query("UPDATE OrderEntity SET inProduction = :order.inProduction WHERE OrderEntity.id = :order.id")
void updateInProduction(@Param("order") OrderEntity order);

我将我的版本更新到了最新版本：

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>4.2.5.Final</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>4.2.5.Final</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-jpa</artifactId>
        <version>1.3.4.RELEASE</version>
    </dependency>

更新： 我也收到此错误：

@Query("SELECT oe FROM OrderEntity oe WHERE oe.id = :orderProductEntity.id")
OrderEntity findBy(@Param("orderProductEntity") OrderProductEntity orderProductEntity);

可悲的是，您不能:order.inProduction（或:foo.bar一般情况下）。 参考。

当你使用这个：

:workstation.workflowProcess

您正在定义一个参数，因此您不能使用该表示法，但您必须使用一个变量：

:workstation
:workflowProcess

等等

实际上错误在 NamedQuery 语法中，你不能像
workflowProcess = :workstation.workflowProcess那样做，
而是应该像
workflowProcess = :workflowProcess

我建议您将属性 nativeQuery 设置为true

@Query(value = "SELECT t.id FROM team as t JOIN project AS p ON p.team_id",
 nativeQuery = true)

您可以在查询中使用 SpEL！这是我的文章。这应该有效：

@Repository
 public interface JobSetRepository extends JpaRepository<JobSetEntity, Integer> {
    @Modifying
    @Transactional
    @Query("UPDATE JobSetEntity SET workstation = :workstation, workflowProcess = :#{#workstation.workflowProcess} WHERE id = :#{#jobSet.id}")
    public Boolean updateWorkstation(@Param("jobSet") JobSetEntity jobSet, @Param("workstation") Workstation workstation);
