Spring - @Value annotation not working when using context.getBean

Question

Here is my app config

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    @Value("${sample.config.application-resources-encoding}")
    private String sMessageSourceEncoding_;

    public WebMvcConfig() {
    }
    
    @Bean
    public MessageSource messageSource() {
        ReloadableResourceBundleMessageSource bean = new ReloadableResourceBundleMessageSource();
        bean.setBasename("classpath:messages");
        bean.setDefaultEncoding(sMessageSourceEncoding_);
        return bean;
    }
}

Here is where I use context.getBean

public class Message {
    
    private MessageSource ms;

    public Message() {
        ApplicationContext context = new AnnotationConfigApplicationContext(WebMvcConfig.class);
        ms = (MessageSource) context.getBean("messageSource");
        ((AnnotationConfigApplicationContext) context).close();
    }
}

At first when WebMvcConfig is loaded, the @Value annotation is working fine but if I use context.getBean, the @Value annotation does not work anymore. Is there any way to make it work using context.getBean?

I know I can just use @Autowired but I'm trying to migrate a struts1 to spring and I need the MessageSource in new instance but I couldn't make the @Value annotation to work the way I want.
