The subject is in the topic - I can't figure out what is the problem with locales switching in my Spring MVC application. As a tutorial I was using that link + I've tried different variations I've found in google. When I click on my web page links to change the language the string ?lang=XX is being appended to the address, but nothing happens.
Here is my servlet-context.xml
<?xml version="1.0" encoding="UTF-8"?>

My controller:

import java.util.Map;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class IndexController {
@RequestMapping("/index")
public String listIndex(Map<String, Object> map) {
return "index";
}
@RequestMapping("/")
public String home() {
return "redirect:/index";
}
}
index.jsp

And I have messages_en.properties and messages_ru.properties in my src/main/resources directory. Apparently, I've missed some details, but I definitely can't catch the problem. BTW, when I am changing the value in <beans:property name="defaultLocale" value="en"/> the languages change properly. I would really appreciate your help.

By default, a Spring Boot application will look for message files containing internationalization keys and values in the src/main/resources folder. The file for the default locale will have the name messages. properties, and files for each locale will be named messages_XX. properties, where XX is the locale code.
The first step towards a localized application is to extract all static text from your templates into a localization file. Later, this is used to look up the required text bits according to the selected language.
Most of the web application frameworks provide easy ways to localize the application based on user locale settings. Spring also follows the pattern and provides extensive support for internationalization (i18n) through the use of Spring interceptors, Locale Resolvers and Resource Bundles for different locales.
<mvc:annotaion-driven /> overrides LocaleChangeInterceptor defined in your XML config. Try to add this (according to spring reference) to XML config:
<mvc:interceptors>
<bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="lang" />
</bean>
</mvc:interceptors>
or try to get rid of <mvc:annotaion-driven />, which is discussed here.

This worked for me as well. Note to others: I may be wrong, but it seems that mvc:interceptors is required when using Spring MVC 3.1. Also note, when using mvc:interceptors make sure you DO NOT have the handlermapping bean:
<bean id="handlerMapping"
class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="interceptors">
<ref bean="localeChangeInterceptor" />
</property>
</bean>
Having this bean causes the error:
"Cannot resolve reference to bean 'localeChangeInterceptor' while setting bean property 'interceptors'" This was the source of my 8 hour frustration.
