Cannot connect to database [default]

Question

I have just started working on play framework. I am trying to build rest api, and is using postgresql for my db connection. It is my first time using both play and postgre. I have made a db connection inside build.sbt. But while running the app I am getting the following issue,

play.api.Configuration$$anon$1: Configuration error[Cannot connect to database [default]]
    at play.api.Configuration$.play$api$Configuration$$configError(Configuration.scala:94) ~[play_2.11-2.3.6.jar:2.3.6]

I have postgre installed in my local in port 5432, my db configuration in application.conf looks like -

 db.default.driver=org.postgresql.Driver
 db.default.url="jdbc:postgresql:localhost:5432/sampledb"
 db.default.user=postgres
 db.default.password="test"

Any help will be highly appreciated, also I will be really grateful, if link to any good tutorial on play with java can be provided. Thanks.

Answer 1

I changed the url string in the format and it picked it up -

db.default.url="postgres://user:password@localhost/MyDbName"
