HQL unexpected AST node: :

问题

My code is failing to inject the below repository. Based on the stack trace, it seems my HQL syntax is invalid, but I'm not sure what I've done wrong.

@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);
}

stack trace:

Update: I'm also getting this error with this query:

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

I updated my versions to the latest:

    <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: I'm also getting this error with:

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

回答1:

Sadly, you cannot do :order.inProduction (or :foo.bar in general). Reference.

回答2:

When you use this:

:workstation.workflowProcess

You're defining a parameter, so you can't use that notation, but you must use a variable as:

:workstation
:workflowProcess

and so on

回答3:

Actually error is in NamedQuery Syntax ,You cannot do like
workflowProcess = :workstation.workflowProcess
instead it should be like
workflowProcess = :workflowProcess
