我正在尝试此JPA查询"SELECT ml FROM MediaLibrary ml WHERE ml.media.id = :id"并收到此错误消息："Cannot find type of (part of) ml.media.id since symbol has no type; implicit variable?"
我意识到应该是某种MEMBER OF查询，但我尝试了同样的结果。我希望找到包含id等于给定值的媒体的媒体库。
简化代码：
@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;
....
我的Mongo数据看起来像我预期的那样：
db.MediaLibrary.find().pretty();
{
"_id" : ObjectId("51bcb440b3060638e5890581"),
....
"media" : [
{
....
"id" : "f0f9b014-24b1-4408-b0aa-3c9f74c822f8",
....
}
]
}
更新：工作命令行mongodb查询是这样的：
db.MediaLibrary.find( { "media" : { $elemMatch : { "id" : "f0f9b014-24b1-4408-b0aa-3c9f74c822f8" } } } );
或在java中：
new BasicDBObject( "media", new BasicDBObject( "$elemMatch", new BasicDBObject("id", id) ) );
更新：另一个查询："SELECT ml FROM MediaLibrary ml WHERE :id MEMBER OF ml.media.id"
并在FINE级别输出：
FINE: JPQL Single-String with "SELECT ml FROM MediaLibrary ml WHERE :id MEMBER OF ml.media.id"

FINE：要在数据存储区中完全评估的过滤器的编译 是不可能的：此映射器不支持调用表达式
因此目前尚未实现将JPQL“collField.contains（val）”（相当于您为查询输入的内容）转换为MongoDB查询，因此无法在数据存储区中对其进行评估。由于您知道需要转换为什么内容，因此您可以轻松获得the code for the DataNucleus MongoDB plugin并找到class QueryToMongoDBMapper并为该特定查询提供支持。
