问题描述

请问我以前是否曾问过这个问题，但是我没有得到直接的答案来帮助我解决问题.我有一个已使用spring-security保护的gwt应用程序. Spring Security只是对用户进行身份验证，然后重定向到gwt应用程序.现在，我希望用户能够从登录页面上的链接更改语言环境，之后该语言环境将存储在Cookie中并在应用程序中使用.

Pardon me if this question has been asked before, but I haven't gotten a straight answer that helped me solve my problem. I have a gwt application that I have secured using spring-security. Spring security just authenticates the user and redirects to the gwt application. Now i want the user to be able to change the locale from a link on the login page after which the locale will be stored on a cookie and used in the app.

在我的applicationContext.xml中，我具有以下配置

I have the following configurations, in my applicationContext.xml

<http auto-config="true">
    <intercept-url pattern="/mywebapp/**" access="ROLE_USER"/>
    <intercept-url pattern="/gwt/**" access="ROLE_USER"/>
    <intercept-url pattern="/**/*.html" access="ROLE_USER"/>
    <intercept-url pattern="/**" access="IS_AUTHENTICATED_ANONYMOUSLY" />
    <intercept-url pattern="/login.jsp*" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
    <form-login login-page="/login.jsp"/>
</http>
<beans:bean id="userDetailsService"
    class="com.kibet.mywebapp.server.auth.UserDetailsServiceImpl">
</beans:bean>

...
<!-- Application Message Bundle -->
<beans:bean id="messageSource"
class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <beans:property name="basename" value="classpath:messages" />
    <beans:property name="defaultEncoding" value="UTF-8"/>
</beans:bean>

<beans:bean id="localeChangeInterceptor"
class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
    <beans:property name="paramName" value="lang" />
</beans:bean>

<beans:bean id="localeResolver"
class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
    <beans:property name="defaultLocale" value="pt"/>
</beans:bean>

<beans:bean id="urlMapping"
     class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <beans:property name="interceptors">
    <beans:list>
        <beans:ref bean="localeChangeInterceptor"/>
    </beans:list>
    </beans:property>
    <beans:property name="mappings">
    <beans:value>/login.jsp=userDetailsService</beans:value>
    </beans:property>
</beans:bean>

这似乎不起作用.我的类路径中有语言环境属性文件messages_en.properties，messages_es.properties和messages_pt.properties.它唯一有效的时间是当我更改浏览器的默认语言环境时. 据我所知，登录页面是由spring-security生成的，并且处理程序映射无法拦截语言环境更改请求.如果这是原因，我将如何处理?非常感谢您的帮助.

This doesn't seem to work. I have the locale properties files messages_en.properties, messages_es.properties and messages_pt.properties in my classpath. The only time it works is when I change the browsers default locale. As far as I can tell, the login page is generated by spring-security and the handler mapping cannot intercept the locale change request. If this is the reason how would I go about this? Help is highly appreciated.

这是我的自定义过滤器代码.

Here's my Custom filter code.

public class InternationalizationFilter implements Filter {

@Override
public void destroy() {
    // TODO Auto-generated method stub

}

@Override
public void doFilter(ServletRequest request, ServletResponse response,
        FilterChain filterChain) throws IOException, ServletException {
    String newLocale = request.getParameter("lang");
    if (newLocale != null) {
        Locale locale = StringUtils.parseLocaleString(newLocale
                .toLowerCase());
        LocaleContextHolder.setLocale(locale);
    }
    try {
        filterChain.doFilter(request, response);
    } finally {

        LocaleContextHolder.resetLocaleContext();
    }
}

@Override
public void init(FilterConfig arg0) throws ServletException {

}}
