spring - @Value not resolved when using @PropertySource annotation. How to configure PropertySourcesPlaceholderConfigurer?

Question

I have following configuration class:

@Configuration
@PropertySource(name = "props", value = "classpath:/app-config.properties")
@ComponentScan("service")
public class AppConfig {

and I have service with property:

@Component 
public class SomeService {
    @Value("#{props['some.property']}") private String someProperty;

I receive error when I want to test the AppConfig configuration class with

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'someService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private java.lang.String service.SomeService.someProperty; nested exception is org.springframework.beans.factory.BeanExpressionException: Expression parsing failed; nested exception is org.springframework.expression.spel.SpelEvaluationException: EL1008E:(pos 0): Field or property 'props' cannot be found on object of type 'org.springframework.beans.factory.config.BeanExpressionContext' 

The issue is documented in SPR-8539

but anyway I cannot figure out how to configure PropertySourcesPlaceholderConfigurer to get it work.

Edit 1

This approach works well with xml configuration

<util:properties id="props" location="classpath:/app-config.properties" />

but I want to use java for configuration.

Answer 1

as @cwash said;

@Configuration
@PropertySource("classpath:/test-config.properties")
public class TestConfig {

     @Value("${name}")
     public String name;


     //You need this
     @Bean
     public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
     }

}
