1. Said to be springboot automatically configured to support MongoDB. An MONGO instance is automatically instantiated when Springboot is started. To add
@SpringBootApplication (exclude = Mongoautoconfiguration.class), but I do not, the original link is as follows.

2. Say in the configuration file to cancel the initial MongoDB (do not know how to cancel)

3. Finally found that I used the idea,spring initializr choice of dependence is testcompile, in the operating environment without

This is the default springboot.

Testcompile ('de.flapdoodle.embed:de.flapdoodle.embed.mongo')

Packaged as a jar to run an error under Linux

Change into

Compile ('de.flapdoodle.embed:de.flapdoodle.embed.mongo')

Normal operation
