Authentication properties MongoDB

[weebl2000]

Currently the MongoProperties class does not take a username and password for the MongoDB database connection.

You can work around this by specifying the authentication credentials in the URI:

spring.data.mongodb.uri=mongodb://user:pass@host/database

I don't really consider that a workaround if it is explicitly supported in the MongoClient (which it appears to be). Do you disagree? I might be open to suggestion for extending MongoProperties to allow other types of credentials to be specified (e.g. with a simple "optionsMap" to build up the URI or something).

[weebl2000]

I was just confused to see it contained database and host, but not user
and password. Database and host could also be left out if we can simply
specify the URI. My point is: it is not very consistent.

[dsyer]

Fair enough. But you have to stop somewhere, so we are destined to be inconsistent in some way (e.g. you can specify URI or host but if you specify a host the URI is ignored). It's a question of maximum convenience for the most common use cases. I suppose you could argue that username/password are the most common form of authentication (in a non-test environment), in which case we could provide those as convenience properties.

I see that password is a char[]. Does this mean I cannot set it in the application.properties file? (It was giving me an error saying no converters can be found to convert string to char[])

[dsyer]

That's kind of idiotic I guess (String->char[] is trivial). Open a new issue (or send a pull request if you want to do that by default). You should be able to add a converter manually by adding your own bean of type ConfigurationPropertiesBindingPostProcessor (with bean name equal to the class name of ConfigurationPropertiesBindingPostProcessor) and inject your own ConversionService.
