Loading credentials from config

Question

I am writing simple rest client with spring boot. In my service class i am using RestTemplate. How to avoid hardcoding url and ApiKey? I tried to use application.properties file and Value annotation but i get null pointer exception. Edit: Injected fields via constructor (using Value annotation). Is it a good practice?

Answer 1

It is wise of you to not want to store url and ap ikey in your application.

I recommend having a properties file stored in your home directory and then reference that file at startup time.

java -jar app.jar --spring.config.location=classpath:/another-location.properties *

*Taken from Properties with Spring and Spring Boot .
