How to pass a parameter as an environment variable

Question

How do you pass a parameter as an environment variable?

Step 1: Open up user bash file 'vim ~/.bash_profile', write the environment variable and save the file

export TWLIO_NUMBER=+303....

Step 2: In the application porperties file, store the variable

twlio_number=${TWLIO_NUMBER}

Step 3: Import Value in order to use it

  import org.springframework.beans.factory.annotation.Value;

  @Value("${twlio_number}")
  private String TWILIO_NUMBER;

Also, if I hardcode the value in the application properties file, the code works.

Use `System.getenv("TWLIO_NUMBER")` to get the value of the exported environment variable? — filbranden, May 02 '20 at 03:23

So I have a system variable in my spring project.

String dataSourceUrl = System.getenv(DEFAULT_CONNECTION);

I am looking for something quick to set the variable in command line.

I found this command work in mac export DEFAULT_CONNECTION=value (value wrap in single quote to prevent the values being replaced)
You can check by env | grep DEFAULT_CONNECTION
run as usual mvn spring-boot:run
