问题


I am trying this JPA query "SELECT ml FROM MediaLibrary ml WHERE ml.media.id = :id" and I get this error message: "Cannot find type of (part of) ml.media.id since symbol has no type; implicit variable?"

I realize that should probably be some kind of MEMBER OF query instead but I tried that with the same result. I am looking to find the media library containing the media with the id equal to the given value.

Simplified code:

@Entity( name = "MediaLibrary" )
@Table( name = "MediaLibrary" )
public class MediaLibrary implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private String mediaLibraryKey;

    @Embedded
    private Set<Media> media;
....

@Embeddable
public class Media implements GenericDataProducer, CreationDateKnown, Serializable {
    private static final long serialVersionUID = 1L;

    @Column
    private String id;
....

My Mongo data looks as I expected:

db.MediaLibrary.find().pretty();
{
"_id" : ObjectId("51bcb440b3060638e5890581"),
    ....
"media" : [
    {
                    ....
        "id" : "f0f9b014-24b1-4408-b0aa-3c9f74c822f8",
                    ....
    }
]
}

UPDATE: the working commandline mongodb query is this:

db.MediaLibrary.find( { "media" : { $elemMatch : { "id" : "f0f9b014-24b1-4408-b0aa-3c9f74c822f8" } } } );

or in java:

new BasicDBObject( "media", new BasicDBObject( "$elemMatch", new BasicDBObject("id", id) ) );

UPDATE: another query: "SELECT ml FROM MediaLibrary ml WHERE :id MEMBER OF ml.media.id"

and output at level FINE:

回答1:


FINE: Compilation of filter to be evaluated completely in-datastore was impossible : Invoke expression is not supported by this mapper

so it is not currently implemented to convert JPQL "collField.contains(val)" (the equivalent of what you typed in for your query) into a MongoDB query, hence cant evaluate it in the datastore. Since you know what it needs converting into, you can easily enough get the code for the DataNucleus MongoDB plugin and find class QueryToMongoDBMapper and contribute support for that particular query.
