Determine Environment in Spring Boot based on Weblogic environment variable

Question

I am trying to determine the environment that the application is in but using the environment variable that Weblogic sets at startup via this line:

-Denvironment=DEV

I have a configuration class below:

package ie.gov.agriculture.cds;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;

@Configuration
@PropertySource("classpath:application.properties")
public class AppConfig {

    @Value("${environment}")
    private String env;

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertyConfigInDev() {
        return new PropertySourcesPlaceholderConfigurer();
    }
}

In the application.properties, if I define the property "environment", then it seems to work, but this is not what I want to achieve. It appears that I need to replace the PropertySource annotation value with something that will point to the weblogic server?

Any help would be much appreciated!

Answer 1

So the solution is that I was missing the property in my weblogic server configuration which is why it was not being picked up.

Inside the domains\%APPCODE%\bin folder of my weblogic server, in the setDomainEnv.cmd file, I included the environment property.

set JAVA_OPTIONS=-Dssoautologin.appcode=%APPCODE% -Denvironment=DESKTOP

This can then be picked up by Spring using the @Value("${environment}") annotation.

Hope this helps someone else!
