Make SessionLocaleResolver's attribute name configurable [SPR-15450]

[spring-projects-issues]

Mercy Ma opened SPR-15450 and commented

I used org.springframework.web.servlet.i18n.SessionLocaleResolver to resolve LocaleContext , and found the attribute name of HttpSession is a constant value ( String LOCALE_SESSION_ATTRIBUTE_NAME = SessionLocaleResolver.class.getName() + ".LOCALE";) , and it still can't be changed in latest version of Spring WebMVC, thus , Is possible to change the attribute name of HttpSession for SessionLocaleResolver ?

Good point! I've introduced corresponding setLocaleAttributeName and setTimeZoneAttributeName methods on SessionLocaleResolver, allowing for customization, and will backport those to 4.3.8 as well.
