HQL 意外的 AST 节点：：

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：

Update:我还通过此查询收到此错误：

@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最新：

    <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>

Update: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，你不能这样做:order.inProduction (or :foo.bar一般来说）。参考 https://stackoverflow.com/questions/10802798/spring-data-jpa-query-with-parameter-properties.
