Please suggest any solution for the above exception, I have given all my files in the above.

Answer 1

Try adding this annotation to your main class file
#EnableAutoConfiguration(exclude={MongoAutoConfiguration.class})

Answer 2

Search services in start.
open it.
search for mongodb there.
start/restart mongodb services from there.
It should work properly.

Answer 3

this exception occurs due to mongodb incorrect port in application properties. So only changing spring.data.mongodb.port=27017 in application.properties file made it work. Also make sure you started mongodb server locally.

Answer 4

Check the connect to MongoDB sever locally with url:portNumber mentioned in the application.properties from where your code is getting executed.
