Bring Lambda environment variables to application.properties file

Question

First of all I am new to Lambda function in AWS and all. I need to access the lambda environment variables into my spring-boot's application.properties file to put RDS username, pass etc. Can someone please give me any hint ?

  datasource:
         url: ${DBURL}
         username: ${UNAME}
         password: ${PASS}

Answer 1

Your example should work as it is in your question, are you getting any errors?

Alternatively, you could rename your environment variables to: SPRING_DATASOURCE_URL, SPRING_DATASOURCE_USERNAME, and SPRING_DATASOURCE_PASSWORD and Spring Boot will automatically pick up those values and use them, without needing anything in application.properties.
