How to access Elastic Beanstalk env var in springboot application

Question

We have a springboot server running on Elastic Beanstalk. 
We want to pull env vars into our .properties file. Currently we have something like

`vars=${ENV_VAR}          <---  in .properties file`

and then in the files something like:

`@Value("${vars}")`

`Private string getvars....`

Locally this works just fine. 
When it's on aws, it seems appears it can't find the variables. 
We have them set in our EB Instance -> Configuration -> Software -> Environment Variables:

Key = ENV_VAR

Value = valueWeExpect

We have "Spring Cloud AWS Autoconfigure" from maven repo as a dependency, but it still doesn't work. Does anyone know if we are missing a dependency or referencing the variables incorrectly.

Answer

Try to inject/autowire org.springframework.core.env.Environment & then access it like below,

@Autowired
private Environment env;
env.getProperty("ENV_VAR");

Hope this helps.
