Mongo tries to connect automatically to port 27017(localhost)

Question

I am using Spring Rest and Mongo in Maven to make a web service that connects to a server. The problem is that I haven\'t written any code for Mongo and it is trying to conn

Answer 1

Spring Boot has a feature called "auto configuration". In this case, as soon as the Mongo driver is detected on the classpath, the MongoAutoConfiguration is activated with default values, which point to localhost:27017. If you don't want that behaviour, you can now either configure the properties for MongoDB (see http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-mongodb for valid property keys) or disable the MongoAutoConfiguration:

@SpringBootApplication(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})

Answer 2

Spring boot throws this exception when Mongo DB is not running. Please make sure that Mongodb is running. It got resolved for me after starting Mongo DB.

Answer 3

for springboot, you should add following config to your application.property

spring.data.mongodb.host=localhost(your mongo server)
spring.data.mongodb.port=27017(mongo port)

Answer 4

In some cases, if you are using reactive you also need to remove MongoReactiveAutoConfiguration

spring:
  autoconfigure:
    exclude:
      - org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration
      - org.springframework.boot.autoconfigure.mongo.MongoReactiveAutoConfiguration
