spring mongo数据存储库接口的"无效十六进制表示"

Question

我有一个存储库接口,如下所示:

public interface ExcursionAttendeeRepository extends MongoRepository<ExcursionAttendee, String> {

    ExcursionAttendee findByWorkflowItemId(String workflowItemId);

    @Query("{ 'excursionEvent._id' : { '$oid' : ?0 } }")
    List<ExcursionAttendee> findByExcursionId(String excursionId);

    @Query("{ 'student._id' : {'$oid' : ?0} , 'excursionEvent._id' : { '$oid' : ?1 } }")
    ExcursionAttendee findByStudentIdAndEventId(String studentId, String excursionId);

    @Query("{ 'student._id' : { '$oid' : ?0 } }")
    List<ExcursionAttendee> findByStudentId(String studentId);
}

而Bean创建spring则抛出异常.

Context initialization failed: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer#0.1':
  Cannot create inner bean '(inner bean)#5172829b' of type [org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter] while setting bean property 'messageListener';
  nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#5172829b':
    Cannot resolve reference to bean 'productDetailsEventConsumer' while setting bean property 'delegate';
    nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'productDetailsEventConsumer': Injection of autowired dependencies failed;
    nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.cinglevue.veip.service.excursion.ExcursionAttendeeService com.cinglevue.veip.service.erp.impl.ProductDetailsEventConsumer.excursionAttendeeService;
    nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'excursionAttendeeServiceImpl': Injection of autowired dependencies failed;
    nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.cinglevue.veip.repository.excursion.ExcursionAttendeeRepository com.cinglevue.veip.service.excursion.impl.ExcursionAttendeeServiceImpl.excursionAttendeeRepository;
    nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'excursionAttendeeRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: invalid hexadecimal representation of an ObjectId: [_param_0]

理想情况下,尝试ObjectId使用无效字符串初始化时,应抛出此异常.[ 代码 ].我想知道如何初始化类以便在创建bean时抛出异常.关于这个的任何提示？

Answer 1

我遇到了同样的问题，以下应该可行。

@Query("{ 'student' : { '$id': ?0 } }")
List<ExcursionAttendee> findByStudentId(String studentId);

如果它是一个 DBRef ，它应该是这样的，（这是我在同一问题后使用的，我的例子中有一个 DBRef ）

@Query("{ 'student': {'$ref': 'user', '$id': ?0} }")
List<ExcursionAttendee> findByStudentId(String studentId);

对于 DBRef 这应该也有效，

List<ExcursionAttendee> findByStudentId(String studentId);

我从这里找到了答案。
