My application has a dependency which comes with default property file having key app_port=$app_port:8080 and property file is sourced in JAR now I want to override value of this key with 8081 and I created another property file and put app_port=$app_port:8081 but it is not overriding value when I am trying to access it using env.getProperty("app_port") or @Value("$app_port")



I tried searching on web but what I found is for boot: https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-external-config
If I pass the value using VM argument -Dapp_port=8081 it is working



Library code:



@PropertySources(
@PropertySource("classpath:config/config.properties")
)
public class MessagingConfig


My application code:



@PropertySources(
@PropertySource("classpath:config/app_config.properties")
)
public class AppConfig


Content of config/app_config.properties



app_port=$app_port:8081


I need a way to override the value of app_port to 8081

app_port=$app_port:8081 basically tells Spring to use the current value of app_port with a default value of 8081.



If you use app_port=8081 inside app_config.properties instead, it should work.
