How to convert java String to ObjectId of mongodb _id using java programming language [duplicate]

Question

e.g:

String hexString = "5afea3b5bc7f8d04fc61d525";

to an ObjectId like

ObjectId("5afea3b5bc7f8d04fc61d525")

Here the above string is obtained from objectId so while writing query in mongodb the _id of mongodb document doesnot match to the string.....Therefore how can i get the matched data from mongodb document by passing string as parameter from rest api to match that _id of mongodb document.

Answer 1

Use:

ObjectId objId = new ObjectId("5afea3b5bc7f8d04fc61d525");
