    import org.springframework.context.ApplicationContext;  
    import org.springframework.context.ApplicationContextAware;  
      
    public class SpringUtil implements ApplicationContextAware {  
      
        private static ApplicationContext applicationContext;  
          
        public static Object getBean(String beanName){  
            return applicationContext.getBean(beanName);          
        }  
          
        @SuppressWarnings("unchecked")  
        public static <T> T getBean(Class cla){  
            return (T)applicationContext.getBean(cla);        
        }  
      
        @Override

            SpringUtil.applicationContext=applicationContext;  
        }  
          
    }

import java.io.IOException;  
    import java.util.Locale;  
      
    import javax.servlet.Filter;

    public class SystemLanguageFilter implements Filter {  
      
        @Override  
        public void init(FilterConfig filterConfig) throws ServletException {  
      
        }  
      
        @Override  
        public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {  
            request.setAttribute(DispatcherServlet.LOCALE_RESOLVER_ATTRIBUTE, SpringUtil.getBean(org.springframework.web.servlet.i18n.CookieLocaleResolver.class));  
            Locale locale = RequestContextUtils.getLocale((HttpServletRequest) request);  
            request.setAttribute("easeyeI18nLang", locale.getLanguage());  
            chain.doFilter(request, response);  
        }

    /**功能: 动态改变系统的语言*/  
    @Controller  
    @RequestMapping("/")  
    public class ChangeLanguageControl {  
      
    protected Logger logger = LoggerFactory.getLogger(getClass().getName());  
      
    @RequestMapping(value = "changelanguage.do")  
    public String changeLanguage(HttpServletRequest request, HttpServletResponse response) {  
    return "redirect:" + request.getParameter("originalUrl");  
    }  
      
    }

easeye-en.js文件加入如下代码(注意引用顺序一定是先引用easeye-en.js后引用easeye-ch.js):

    	Current Locale : ${pageContext.response.locale}  
    </font>  
      
    <a href="${ctx}/changelanguage.do?language=en">EN</a>
