Jhipster mongodb

Question

I try to connect my webapp, built by jhipster to the mongodb at mlab.com I can connect to the db with mongo shell, but when I run the webapp, I get the following trace (below): In application-dev.yml, I have set the following: data: mongodb: uri: mongodb://dpa:pass@ds055862.mlab.com:55862 database: mydb

Is it something more that needs to be set ?

Answer 1

It seems that the default configuration of JHipster isn't adapted to be used with external databases such as mLab. Try to put the following configuration in your application-dev.yml instead.

data:
    mongodb:
        host: ds055862.mlab.com
        port: 55862
        database: mydb
        username: dpa
        password: pass
