how can I set locale for Surf Application?

[mryoshio]

Hello everyone,

I'm trying to make Spring Surf work with Alfresco and
set locale as user select in login page.
I actually set locale but messages of xxxx.get_ja.properties are always displayed whatever locale I choose.

So far, I've done for customization as followings.

####### [ADD]
jp.aegif.springframework.extensions.surf.mvc.Local eResolver
this class receives request parameter sent from login.ftl and set locale using I18NUtil#setLocale.

jp.aegif.springframework.extensions.surf.mvc.Login Controller
replaced default LoginController with this class to set locale in it.

####### [CHANGE]
SRC_MAIN_WEBAPP/WEB-INF/templates/sample/loginf.ftl
added select component which includes values "en_US", "de_DE" and "ja_JP".


SRC_MAIN_WEBAPP/WEB-INF/config/web-application-config.xml
override default LoaleResolver bean definition with custom LocaleResolver class.
<bean id="localeResolver"
class="jp.aegif.springframework.extensions.surf.mv c.LocaleResolver" />

override default LoginController bean definition with custom LoginController class.
<bean id="loginController"
class="jp.aegif.springframework.extensions.surf.mv c.LoginController">
<property name="cacheSeconds" value="-1" />
<property name="useExpiresHeader">
<value>true</value>
</property>
<property name="useCacheControlHeader">
<value>true</value>
</property>
</bean>

#######
and comment out default Surf codes because I want to let Surf work using locale selected in login.
org.springframework.extensions.surf.site.servlet.B aseServlet
56 //I18NUtil.setLocale(I18NUtil.parseLocale(language)) ;

org.springframework.extensions.webscripts.servlet. mvc.WebScriptView
119 //I18NUtil.setLocale(I18NUtil.parseLocale(language)) ;

org.springframework.extensions.webscripts.servlet. WebScriptServlet
141 //I18NUtil.setLocale(I18NUtil.parseLocale(language)) ;

#######
I also debugged by changing I18NUtil#getLocale as...
98 public static Locale getLocale()
99 {
100 Locale locale = threadLocale.get();
101 System.err.println("threadLocale: " + threadLocale.toString());
102 if (locale == null)
103 {
104 // Get the default locale
105 locale = Locale.getDefault();
106 System.err.println("[aegif] I18NUtil: locale == null. Get DefaultLocale");
107 } else {
108 System.err.println("[aegif] locale already set -> " + locale);
109 }
110 return locale;
111 }

Outputs are...
[aegif] locale already set -> en_US
threadLocale: java.lang.ThreadLocal@6f1dc409
[aegif] locale already set -> en_US
threadLocale: java.lang.ThreadLocal@6f1dc409
[aegif] I18NUtil: locale == null. Get DefaultLocale (**NOTE: Where has "en_US" setting gone?)
threadLocale: java.lang.ThreadLocal@6f1dc409
[aegif] I18NUtil: locale == null. Get DefaultLocale

Locale seems to be set with "en_US" a bit after login.
But "en_US" disappears suddenly.

Why does it happen? Do I have any mistakes?
Thanks in advance.

My Spring Surf version is 1.0.0.M3.

SpringSurf (and SpringMVC) are naturally wired up to set the locale to whatever is passed in the browser language header value. I assume what you want to do is override that, i.e. fix the locale from a selection on the login page?

kroast,

Thanks for reply, and that's right. It's what I want to do.
But Spring Surf won't work as I want it to.

I missed something?

Hi,

The SpringSurf locale handling is provided by a spring bean:

    <!-- Locale Resolver -->
    <bean id="localeResolver" class="org.springframework.extensions.surf.mvc.LocaleResolver" />

If you override that with your own impl that will get your started - currently this bean looks at the Accept-Header and applies it to the I18N util class.

SpringMVC provides a couple of these beans that you might want to look at:
org.springframework.web.servlet.i18n.AcceptHeaderL ocaleResolver
org.springframework.web.servlet.i18n.CookieLocaleR esolver
org.springframework.web.servlet.i18n.FixedLocaleRe solver
org.springframework.web.servlet.i18n.SessionLocale Resolver

Hi,

Thanks for information.
Finally I succeeded in setting locale with using custom interceptor which makes use of session attribute.

Unfortunately I couldn't fulfill my purpose when I use custom class which extends SessionLocaleResolver.

thanks
