Qdrant does not support java.lang.Long as a native payload type.
Previously, passing a Long value caused the following exception:
java.lang.IllegalArgumentException: Unsupported Qdrant value type: class java.lang.Long
at org.springframework.ai.vectorstore.qdrant.QdrantValueFactory.value(QdrantValueFactory.java:85)
at org.springframework.ai.vectorstore.qdrant.QdrantValueFactory.lambda$toValueMap$1(QdrantValueFactory.java:46)
...
To resolve this, Long values are now converted to their String representation
in QdrantValueFactory. This preserves precision and avoids serialization issues.
test(qdrant): add test to verify Long metadata values are stored as String
Adds a test to ensure that Long values in document metadata are
safely converted to String before being stored in Qdrant.
The test inserts a document with a Long-type "ref_id", performs
a similarity search, and verifies that:
- the result is not empty,
- the retrieved "ref_id" is a String,
- the value matches the original Long when parsed.
Also ensures cleanup by deleting the inserted document from the store.
