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

For any other poor souls who couldn't get this to work in some Configuration classes when they work in others:

Look to see what other beans you have in that class and if any of them get instantiated early in the ApplicationContext. A ConversionService is an example of one. This would instantiate the Configuration class before what is required is registered, thereby making no property injection take place.

I fixed this by moving the ConversionService to another Configuration class that I Imported.
