Getting localized message from resourceBundle via annotations in Spring Framework

Question

Is it possible to do this ? Currently it is done like this :

Answer 1

The point is that this is really useful only for Unit Testing. In real application, Locale is a runtime information that cannot be hardcoded in the annotation. Locale is decided based on Users locales in Runtime.

Btw you can easily implement this by yourself, something like :

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.FIELD})
public @interface Localize {

    String value();

}

And

public class CustomAnnotationBeanPostProcessor implements BeanPostProcessor {

    public Object postProcessAfterInitialization(Object bean, String beanName) {
        return bean;
    }

    public Object postProcessBeforeInitialization(Object bean, String beanName) {
        Class clazz = bean.getClass();
        do {
            for (Field field : clazz.getDeclaredFields()) {
                if (field.isAnnotationPresent(Localize.class)) {
                    // get message from ResourceBundle and populate the field with it
                }
            }
            clazz = clazz.getSuperclass();
        } while (clazz != null);
        return bean;
    }
