如何在泛型方法中获取firestore文档id？

import com.google.cloud.firestore.CollectionReference;
import com.google.cloud.firestore.DocumentReference;
import com.google.cloud.firestore.Firestore;
import com.google.cloud.firestore.FirestoreOptions;

public class FirestoreUtils {
    private static final String PROJECT_ID = "your-project-id";
    private static final String COLLECTION_NAME = "your-collection-name";

    public static <T> void getDocumentId(T document) {
        FirestoreOptions firestoreOptions = FirestoreOptions.getDefaultInstance().toBuilder()
                .setProjectId(PROJECT_ID)
                .build();
        Firestore firestore = firestoreOptions.getService();

        CollectionReference collectionRef = firestore.collection(COLLECTION_NAME);
        DocumentReference documentRef = collectionRef.document();

        String documentId = documentRef.getId();
        // Do something with the document ID
    }
}
