Spring boot reference file location from resources in properties file

Question

I have a Spring Boot application using Google Pub Sub API. I need to inject Google credentials and other properties using file credentials.json. I put the file

Answer 1

If you use the classpath prefix then Spring will look for the file on your classapth.

If you put the file in src/main/resources then Maven will, by default, copy it to the root of your classpath and it will then be addressable as follows:

spring.cloud.gcp.credentials.location=classpath:credentials.json

This should hold true whether ...

• You are running in your IDE; your IDE's Maven integration will copy the file from src/main/resources to the root of your classpath - typically target/classes
• You are running a built JAR; Maven will copy the file from src/main/resources to the root of your JAR
