MongoDB Atlas Java 驱动程序 TLS 问题

Question

I have a Java based server running in Docker using openjdk:15-jdk-alpine. It connects to MongoDB Atlas using the mongodb-driver-reactivestreams driver. Similarly I have a second SpringBoot based server running in Docker that connects using the same credentials and runs just fine.

When I run my code in in IntelliJ it runs without errors, connects to MongoDB and I can query, insert documents ect...

When I put it in a Docker container and spin up the server, I get the following error message: Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.mongodb.internal.connection.tlschannel.TlsChannel

When I disable tls using tls=false in the connection string I get the message MongoSocketReadException: Prematurely reached end of stream .

In both instances, when looking through the log I can see that the server was able to identify all the shards in my MongoDB cluster, so it is connecting to Mongo Atlas and receiving information back.

My current theory is that 1) Tls is required to connect 2) Tls is not working in my docker container for some reason to do with the JVM key store/truststore.

I dont know enough about TLS or Java key store stuff to debug this, and dont know what to search to get to an answer. If anyone can point me in the right direction it will be much appreciated...

Answer 1

This issue is very likely to be connected with this (already fixed) bug https://jira.mongodb.org/browse/JAVA-4656 (driver fails to parse java.version property if it contains only dashes and no dots, 15 , 15.0.1 or 15.0.1-something works fine, but 15-whatever fails)

So the solution is to update your mongo driver to the latest version or maybe to update your java version to version with some dots
