How to set replica set in spring boot?

I Have a spring boot server and I want to connect it to my mongoDB replica set. (3 servers in the set)

1.in application.properties I configured:

spring.data.mongodb.uri=mongodb://user:[email protected]:27017/admin

but if I try to write to server that is not the primary I get error. so how can I configure it that my spring boot app always know who is the primary and write to the primary?

I know there is an option to write :

spring.data.mongodb.uri=mongodb://user:[email protected]:27017,172.1.1.2:27017,172.1.1.3:27017/admin

but it throws me an exception:

        2016-09-11 14:14:54.811  INFO 3128 --- [-31-61-35:27017] org.mongodb.driver.cluster               : Exception in monitor thread while connecting to server ip-172-1-1-2:27017

  1. I always connect to the admin DB. but I need access to another db because my collection is there. how can I configure that the user will connect to all db? because this user will work with different dbs and different collections?

Thanks a lot

In this other answer (How to configure spring-data-mongodb to use a replica set via properties) , one of the answer (from @nwolfe) says this:

... found that the code was ignoring the uri value if there were any values configured for spring.data.mongodb.host, spring.data.mongodb.port, spring.data.mongodb.username or spring.data.mongodb.password. If I put all that information in the uri (and removed all the other spring.data.mongodb.* values from the property file), the connection code worked.

Here's how you can define the URIs, from the spring documentation:

You can set spring.data.mongodb.uri property to change the URL and configure additional settings such as the replica set:

spring.data.mongodb.uri=mongodb://user:[email protected]:12345,mongo2.example.com:23456/test
