How to determine if a string can be used as a MongoDB ObjectID?

Question

I am using Micronaut framework with JAVA and trying to validate the objectId with the below string.

60236833af6a1d49478d2bef   // Valid mongo ObjectId

60236833a46a1d49478d2bef  // Invalid mongo ObjectId

How can I perform either the string has valid objectId or not in Java with MongoDb?

Answer 1

This work for me

import org.bson.types.ObjectId;

if(ObjectId.isValid(value)){
}

Answer 2

You can refer to the ObjectId specification for how they are generated.

Any 24-character hexadecimal string should be convertable to an ObjectId.
