I can't exclude MongoAutoConfiguration in Spri

问题:

I'm getting a MongoSocketOpenException when trying to exclude MongoAutoConfiguration. I'm trying to connect to a remote MongoDB. Is the @EnableAutoConfiguration syntax correct considering I'm working in Kotlin?

Exception:

回答1:

There's no java-like array initialization in Kotlin. It should be

@EnableAutoConfiguration(exclude = arrayOf(MongoAutoConfiguration::class))

回答2:

Its better this way

@EnableAutoConfiguration(exclude = [MongoAutoConfiguration::class])
