I am generating models to be saved in MongoDB using protobuf java. I want to generate a custom _id field.
Can anyone let me how to achieve this?
I have tried adding the _id field, but it is not working as expected.
syntax = "proto3";
message User {
string first_name = 1;
string last_name = 2;
int64 dob = 3; // dob in the epoch format
int64 phone = 4;
string email = 5;
string type = 6;
string role = 7;
string user_id = 8;
bytes password = 9;
bool is_active = 10;
Meta meta = 11;
AddViaEnum addedVia = 12;
Address address = 13;
int64 _id = 14;
}
Please find below the code to connect to MongoDB and inserting the document.
@Slf4j
public class CrudDaoImpl implements CrudDao {
private MongoClient mongoClient;
private MongoDatabase mongoDatabase;
@Inject
public CrudDaoImpl(MongoClient mongoClient) {
this.mongoClient = mongoClient;
this.mongoDatabase = this.mongoClient.getDatabase("test");
log.info("Connected to database");
}
@Override
public void saveDocument(String collectionName, String request) throws IOException {
MongoCollection<Document> collection = mongoDatabase.getCollection(collectionName);
collection.insertOne(Document.parse(request));
}
}
I am using google guice for dependency injection. Initializing mongo client as below
@Provides
public MongoClient get() {
return MongoClients.create("mongodb://localhost:27017");
}
After inserting the document in the mongodb through the java application with the above set-up, mongo is creating ObjectID as the _id. I wanted custom generated _id and I am not sure how to define that in protobuf.
