Spring Boot connect to Atlas MongoDB issue

Question

I am trying to connect my Atlas MongoDB instance from Spring Boot using the following properties:

spring.data.mongodb.uri=mongodb+srv://<usr>:<pass>@<my-cluster-prefix>.gkyoqkx.mongodb.net/?retryWrites=true&w=majority
spring.data.mongodb.database=my-db

The connection string I've got from the Atlas "Connect"->"Connect your application" so should be valid. But when I start my app I see the following exception:

2022-08-22 17:13:42.836  INFO 52641 --- [ngodb.net:27017] org.mongodb.driver.cluster               : Exception in monitor thread while connecting to server ac-opxd8w6-shard-00-02.gkyoqkx.mongodb.net:27017

which is looking strange since by default it shouldn't be using SSL to connect (afaik). I also whitelisted all IPs by adding 0.0.0.0/0 to the Network Access in Atlas.

And btw, when I am trying to connect from my Mac with mongosh and the same connection URI it works perfectly.

Any piece of advice is appreciated.

Atlas MongoDB version: 5.0.10, Mongo driver version: 4.6.1

Answer 1

Same issue here, I fixed it upgrading Java version from 11 to 17, you shoud try it as an alternative solution. This is a known bug in mongodb-driver-sync with JKD 13.0.2, solved in Java versions >= 13.0.5. check official mongo forum discussion here

The question is: to upgrade Java is not a solution if the issue is according to the connection driver. I'll come here again if I find something new.
