Invalid mongo configuration, either uri or host/port/credentials must be specified - mongodb

Question

I'm getting this exception :
Caused by: java.lang.IllegalStateException: Invalid mongo configuration, either uri or host/port/credentials must be specified

Here is my application.yml content :
spring:
data:
mongodb:
uri: mongodb://develop:d3VeL0p$#<my_host>:27017/SHAM
Here is my configuration class :
package com.me.service.testservice.config;
import com.mongodb.MongoClient;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
#Configuration
#EnableMongoRepositories(basePackages = {"com.me.service.testservice.repository"}, considerNestedRepositories = true)
public class SpringMongoConfiguration {
#Bean
public MongoTemplate mongoTemplate() throws Exception {
return new MongoTemplate(new MongoClient("<my_host>"), "SHAM");
}
}
Now I'm getting this stack trace when starting without failing, it looks like user develop doesn't have the right to connect:
Caused by: com.mongodb.MongoCommandException: Command failed with error 18: 'Authentication failed.' on server phelbwlabect003.karmalab.net:27017. The full response is { "ok" : 0.0, "errmsg" : "Authentication failed.", "code" : 18, "codeName" : "AuthenticationFailed" }

Answer 1

You are mixing the uri style connection settings with the individual properties style settings.
Either use
spring:
data:
mongodb:
host: localhost
port: 27017
database: SHAM_TEST
username: develop
password: pass
Or
spring:
data:
mongodb:
uri:mongodb://develop:pass#localhost:27017/SHAM_TEST

Answer 2

If your project has more then one application.properties/application.yml file, sometime they both conflicts if one has URI and other has Host/Port/Credential.
This result in the error "Invalid mongo configuration, either uri or host/port/credentials must be specified"
To Avoid the conflict, make sure you either use URI or Host/Port/Credential in all.

Answer 3

The issue was authentication-database was missing.
Here is now the working configuration :
spring:
data:
mongodb:
host: <my_host>
username: develop
password: d3VeL0p$
port: 27017
database: SHAM
repositories:
enabled: true
authentication-database: admin

Answer 4

If you are using application.properties file to store your configuration, Use the following structure.
spring.data.mongodb.host = localhost
spring.data.mongodb.port = 27017
spring.data.mongodb.database = SHAM_TEST
spring.data.mongodb.username = develop
spring.data.mongodb.password = pass

Answer 5

This issue appears with mongo version 4.x,
spring or spring boot supports version 2.x only so when we try to connect with mongo 4 this error appears:
Downgrade your mongo from 4.x to 3.x or lower.
If not, then change these placeholders.
Change from :
spring.data.mongodb.host= localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database= your db name
spring.data.mongodb.username= something
spring.data.mongodb.password= ***
-to-
mongo.replica.hosts=localhost:27017
mongo.dbname= your db name
mongo.username= something
mongo.password= ***
