How to create an uberjar correctly with "lein uberjar"? - clojure

Question

if I use lein run the project is no problem.
But when I use jave -jar blog.jar after lein uberjar It happen exceptions.

:test [:project/test :profiles/test]
:project/dev ...
:project/test ...
:profiles/dev {:env {:database-url "jdbc:postgresql://localhost/blog?user=postgres&password=root"}}
:profiles/test {}})
Maybe it can't find the key of "database-url"?

Answer 1

Data provided via environment settings in project.clj are not provided when you use java directly. It's your responsibility to make sure the environment settings visible to the app provide any credentials or connection info needed.
It could look something like:
DATABASE_URL="jdbc...." java -jar my-project-standalone.jar
