Spring CookieLocaleResolver: set cookiePath - spring

Question

Is it possible to set cookiePath with the value of application name (automatically)?
For example I have a test.war so it will be available at bla.com/test/ so I want my cookie's path be /test/ and not / that is default value.
Thank you

When you create the CookieLocaleResolver you can set the path, but it will be hard coded.
Ex
<bean id="localeResolver" class="CookieLocaleResolver">
<property name="cookiePath" value="test" />
</bean>
Another possible solution is to override the LocaleResolver
public class MyCookieLocaleResolver extends CookieLocaleResolver {
#Override
public void setLocale(HttpServletRequest request,
HttpServletResponse response, Locale locale) {
if (locale != null) {
// Set request attribute and add cookie.
request.setAttribute(LOCALE_REQUEST_ATTRIBUTE_NAME, locale);
addCookie(response, locale.toString());
} else {
// Set request attribute to fallback locale and remove cookie.
request.setAttribute(LOCALE_REQUEST_ATTRIBUTE_NAME,
determineDefaultLocale(request));
removeCookie(response);
}
}
public void addCookie(HttpServletRequest request,
HttpServletResponse response, String cookieValue) {
Cookie cookie = createCookie(request, cookieValue);
Integer maxAge = getCookieMaxAge();
if (maxAge != null) {
cookie.setMaxAge(maxAge);
}
if (isCookieSecure()) {
cookie.setSecure(true);
}
response.addCookie(cookie);
if (logger.isDebugEnabled()) {
logger.debug("Added cookie with name [" + getCookieName()
+ "] and value [" + cookieValue + "]");
}
}
protected Cookie createCookie(HttpServletRequest request, String cookieValue) {
Cookie cookie = new Cookie(getCookieName(), cookieValue);
if (getCookieDomain() != null) {
cookie.setDomain(getCookieDomain());
}
cookie.setPath(request.getContextPath());
return cookie;
}
}

If you use a ServletContainer >= 2.5 and spring annotation, you can use the following code to get the ContextPath, so you don't have to hardcode:
#EnableWebMvc
#Configuration
#ComponentScan("com.controller")
public class WebConfig extends WebMvcConfigurerAdapter {
#Autowired
private ServletContext servletContext;
#Bean
public LocaleResolver localeResolver(){
CookieLocaleResolver resolver = new CookieLocaleResolver();
resolver.setDefaultLocale(new Locale("en"));
resolver.setCookieName("locale");
resolver.setCookiePath(servletContext.getContextPath());
resolver.setCookieMaxAge(31536000);
return resolver;
}
}
