spring mongodb: Unable to get document by id - Parameter does not have a name

Question

Here my related code:

Optional<Resource> resource = resourceMongoRepository.findById("65df60edbd43c107768b6191");

I'm getting:

Caused by: org.springframework.data.mapping.MappingException: Parameter org.springframework.data.mapping.Parameter@c946e82b does not have a name

My repository is:

public interface ResourceMongoRespository
    extends MongoRepository<Resource, String> {

}

Related mongo generated query log:

DEBUG 189104 --- [tContainer#0-24] o.s.data.mongodb.core.MongoTemplate : findOne using query: { "_id" : "65df60edbd43c107768b6191"} fields: Document{{}} for class: class net.gencat.transversal.espaidoc.infrastructure.model.Resource in collection: resource

Into my mongosh:

test> db.resource.find({"_id" : ObjectId("65df60edbd43c107768b6191")});
[
  {
    _id: ObjectId('65df60edbd43c107768b6191'),
    resourceId: Binary.createFromBase64('MkpJzQuAUBwhFCqfXjT4ow==', 3),
    resourceLocation: { location: '1c50800b-cd49-4a32-a3f8-345e9f2a1421', type: 'S3' },
    documentState: 'PENDING',
    _class: 'net.gencat.transversal.espaidoc.infrastructure.model.Resource'
  }
]

I write fill caused by:

Any ideas?

Answer 1

This has to do with Spring not being able to identify the fields in some object, I presume that will be that Resource object. Most probably it cannot identify the name of the parameters for the constructor in place.

You can put a breakpoint in that class PersistentEntityParameterValueProvider and see exactly the field that it is trying to map.

Posible solutions are:

• Add a no args constructor to that class
• For immutable objects, migrate them to a Java Records
• If the problem is with the String value, wrap it in an object (e.g. a record)
