spring mvc 3 国际化（下）——简单自定义操作

根据域名来判断用户语言：

1.定义一个对象;SelfLocaleResolver

public class SelfLocaleResolver extends AbstractLocaleResolver {
    @Override
    public Locale resolveLocale(HttpServletRequest request) {
        if ("127.0.0.1".equalsIgnoreCase(request.getRemoteHost())) {
            return new Locale("zh");
        } else {
            return new Locale("en");
        }
    }

    @Override
    public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) {
    }

}

 这里是表示 访问的域名是 127.0.0.1 则显示为中文 访问其它为英文

2.配置文件中加入

 

<bean id="localeResolver" class="com.xxx.SelfLocaleResolver"/>

 

3.结束

LocaleChangeInterceptor的源码：

LocaleChangeInterceptor 的作用：URL中传递一个参数来修改用户语言。http://localhost:8080?change=en

 

 

public class LocaleChangeInterceptor extends HandlerInterceptorAdapter {


    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
            throws ServletException {
                //获取用户传递的参数
        String newLocale = request.getParameter(this.paramName);
        if (newLocale != null) {
                        //localeResolver 为在配置文件中配置的对象
            LocaleResolver localeResolver = RequestContextUtils.getLocaleResolver(request);
            if (localeResolver == null) {
                throw new IllegalStateException("No LocaleResolver found: not in a DispatcherServlet request?");
            }
                        //cookie和session存储的时候才可以修改。
            localeResolver.setLocale(request, response, StringUtils.parseLocaleString(newLocale));
        }
        return true;
    }

}
