使用属性启动Spring Boot

Question

I want to pass properties for spring boot project from command line. I have following configuration in my yaml config file:

server:
    port: ${port}

but when I starts project from command line like:

java -jar myapp.jar -Dport=8085

I get following error:

 Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'port' in value "${port}" 

Did I miss anything in my configuration?
