Configuration in WebApplicationInitializer

[andreas.antener]

Hi all

I'm using Spring code based configuration to setup my webapp which works fine.

Initializer:

public class AppInit implements WebApplicationInitializer {
    @Override
    public void onStartup(final ServletContext container) {
        // Create the 'root' Spring application context
        final AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
        rootContext.register(AppConfig.class);

        // Manage the lifecycle of the root application context
        container.addListener(new ContextLoaderListener(rootContext));
        container.addListener(new RequestContextListener());
        container.addListener(new Log4jConfigListener());

        // Add filters
        // TODO: Need configuration values here
    }
}

Configuration:

@Configuration
@ComponentScan(basePackages = "package")
@PropertySource("${applicationConfigLocation}")
// importing other configuration classes
// ...
public class AppConfig {

    @Bean
    public PropertySourcesPlaceholderConfigurer pspc() {
        return new PropertySourcesPlaceholderConfigurer();
    }
}

What I'm trying to do now is configuring my filters with properties from the same source as @PropertySource("${applicationConfigLocation}").
${applicationConfigLocation} is defined in the context of the web application and points to some property file in the classpath.

Is there any good/clean way to do this? Something like telling Spring to load the configuration already in WebApplicationInitializer#onStartup? If possible, I'd like to prevent manually loading the property file..

Cheers
