Question

I’m trying to creating a utility class with some static methods and properties, the problem is that these properties should be loaded from the messages.properties files, for multilingual porpouse.

I think I should use the MessageSourceAware but how to keep the methods static? I’m getting quite lost..

And more, how I can get the Locale? We’re using a SessionLocaleResolver but I think that in the jsp is automatically loaded. How can I get it in a class?

[Thanks, I’m quite new in Spring]

I’ll try to explain it a little better.

I’ve a class defined like

public MyClass {
    protected static final MY_PROP = "this is a static property";

    protected static String getMyProp() {
        return MY_PROP;
    }
}

and I would like to inject the MY_PROP from my messages.properties file, depending on the Locale, something like

public MyClass {
    protected static final MY_PROP = messageSource.getMessage("my.prop", locale);

    protected static String getMyProp() {
        return MY_PROP;
    }
}

Is this possible soomehow?

Ok, in the end I’ve implemented the MessageSourceAware, removed the static references and injected my class.

So something like:

public MyClass implements MessageSourceAware {
    // this is automatically injected by Spring
    private MessageSource messageSource;
    public void setMessageSource(MessageSource messageSource) {
        this.messageSource = messageSource;
    }
    // ###################

    protected String getMyProp(Locale locale) {
        return messageSource.getMessage("my.prop", null, locale);
    }
}

and in my Rest service the Locale is automatically injected by Spring, thanks to the RequestMapping. I’ve injected also the entire class to avoid the static methods.

@Controller
public class Rest {

    @Autowired
    private MyClass myClass;

    @RequestMapping(method = RequestMethod.POST, value="/test", headers="Accept=application/json")
    public String myMethod(Locale locale) {
        return myClass.getMyProp(locale);
    }
}

and this is working. : )
