How to read properties value from interface in java

Question

I would like to read testvalue from properties file in java, can someone please help Following is my code

package com.test;

import java.util.Map;

import com.amazonaws.services.lambda.invoke.LambdaFunction;

public interface LambdaPDFService {
    @LambdaFunction(functionName="**testValue**")
    Map<String, String> setResponse(LambdaPdfRequest input);
}

I have tried below annotation, and e.tc but it's not working

@PropertySources(@PropertySource("classpath:application.properties"))

Answer 1

You can't read in an interface.

You can read in a concrete class annotated as a @Service (or @Component). Assuming application.properties includes lambda.function.name=foo

@Service
public class LambdaPDFServiceImpl implements LambdaPDFService {
    @LambdaFunction(functionName="${lambda.function.name}")
    Map<String, String> setResponse(LambdaPdfRequest input) {
        // TODO
    }

}
