Cannot connect to mongoDB using Spring Data Reactive and Spring Boot 2.0 - ssl

Question

I get the following error every time I trying to connect to MongoDB using Spring Data Reactive and Spring Boot 2.0.
Caused by: java.lang.UnsupportedOperationException: No SSL support in java.nio.channels.AsynchronousSocketChannel. For SSL support use com.mongodb.connection.netty.NettyStreamFactoryFactory

The error message tells me to use NettyStreamFactoryFactory for SSL support. Does anyone have any examples on how to do this? The database I am trying to connect to is MongoDB Atlas, it strictly require a SSL connection.
Below is the rest of my code:

Answer 1

Try
in connection String
xxxx?ssl=true&sslInvalidHostNameAllowed=true&streamType=netty
or Via MongoClientSettings
EventLoopGroup eventLoopGroup = new NioEventLoopGroup(); // make sure application shuts this down
#Bean
public MongoClient getClient()
{
return MongoClients.create(MongoClientSettings.builder()
.clusterSettings(ClusterSettings.builder()
.hosts(Arrays.asList(new ServerAddress()))
.build())
.streamFactoryFactory(NettyStreamFactoryFactory.builder()
.eventLoopGroup(eventLoopGroup).build())
.sslSettings(SslSettings.builder()
.enabled(true)
.build())
.build());
}
#PreDestroy
public void shutDownEventLoopGroup() {
eventLoopGroup.shutdownGracefully();
}

Answer 2

This sounds like a Spring Data Mongo and/or Spring Boot issue.
At first it seems Spring Boot is giving the appropriate information to the Spring Data Mongo client configuration.
Could you create an issue on the dedicated issue tracker for Spring Data Mongo?

Answer 3

As mp911de mentioned above, adding Netty dependency in your pom will solve the problem.
For me, adding the spring-boot-starter-webflux resolved the issue.

Answer 4

It's the MongoClient who is responsible for managing the connection. In your case it is the default unprotected one, so if you have security enabled on your Mongo instance he will bounce back.
#Configuration
#EnableReactiveMongoRepositories
class MongoConfig : AbstractReactiveMongoConfiguration() {
override fun reactiveMongoClient(): MongoClient = MongoClients.create()
override fun getDatabaseName(): String = "mydb"
}
This is my configuration for reactive mongo in spring boot 2 M4. You can customize your client via MongoClients methods or appropriate constructor.
