Spring @Configuration file with PropertyPlaceholderConfigurer bean doesn't resolve @Value annotation

Question

I have following configuration file:

@Configuration
public class PropertyPlaceholderConfigurerConfig {

    @Value(\"${property:defaultValue}\")
    private          


        

Answer 1

If you run your application using VM option and then want to access that option in your application you have to do it slightly different:

@Value("#{systemProperties.property}")
private String property;

Your PropertyPlaceholderConfigurer is not aware of system properties, also note that you are accessing properties using $ - which refers to place holders and # refers to beans, where systemProperties is a bean.
