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

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();
     }

}

If you use @PropertySource, properties have to be retrieved with:

@Autowired
Environment env;
// ...
String subject = env.getProperty("mail.subject");

If you want to retrieve with @Value("${mail.subject}"), you have to register the prop placeholder by xml.

Reason: https://jira.springsource.org/browse/SPR-8539

I found the reason @value was not working for me is, @value requires PropertySourcesPlaceholderConfigurer instead of a PropertyPlaceholderConfigurer. I did the same changes and it worked for me, I am using spring 4.0.3 release. I configured this using below code in my configuration file.

@Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
   return new PropertySourcesPlaceholderConfigurer();
}
