登录时更改区域设置 [英] Change locale on login
问题描述
我想在登录到使用Spring Security(3.0)的用户帐户Spring MVC Application(3.0)中存储的默认语言环境后更改语言环境。
I want to change the locale after login to an default locale stored in the user account Spring MVC Application (3.0) with Spring Security (3.0).
我已经使用 LocaleChangeInterceptor
,以便(未登录,以及登录)用户可以更改其区域设置(默认来自accept标头)。但是客户真的想要特定于帐户的默认值。
I already use the LocaleChangeInterceptor
so a (not logged in, as well a logged in) user can change its locale (with default from the the accept header). But the customer really want that account specific default.
所以我的问题是,登录后更改区域设置的最佳方法是什么,或者是否已经有一些内置版本Spring / Security中的功能?
So my question is, what would be the best way to change the locale after login, or is there already some build in functionality in Spring/Security?
推荐答案
我能找到的最佳解决方案是在AuthenticationSuccessHandler中处理这个问题。
The best solution I was able to find was to handle this in the AuthenticationSuccessHandler.
以下是我为我的创业公司编写的一些代码:
The following is some code I wrote for my startup:
public class LocaleSettingAuthenticationSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {
@Resource
private LocaleResolver localeResolver;
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
setLocale(authentication, request, response);
super.onAuthenticationSuccess(request, response, authentication);
}
protected void setLocale(Authentication authentication, HttpServletRequest request, HttpServletResponse response) {
if (authentication != null) {
Object principal = authentication.getPrincipal();
if (principal instanceof LocaleProvider) {
LocaleProvider localeProvider = (LocaleProvider) principal;
Locale providedLocale = localeProvider.getLocale();
localeResolver.setLocale(request, response, providedLocale);
}
}
}
}
您的主要类应提供以下接口。
这不是必需的,但我正在使用它,因为我有多个对象能够为会话提供区域设置。
And the following interface should be offered by your principal class. This is not needed but I'm using it since I have multiple objects capable of providing a locale for the session.
public interface LocaleProvider {
Locale getLocale();
}
配置片段:
<security:http ...>
<security:custom-filter ref="usernamePasswordAuthenticationFilter" position="FORM_LOGIN_FILTER"/>
</security:http>
<bean id="usernamePasswordAuthenticationFilter"
class="org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter">
<property name="filterProcessesUrl" value="/login/j_spring_security_check"/>
<property name="authenticationManager" ref="authenticationManager"/>
<property name="authenticationFailureHandler">
<bean class="org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler">
<property name="defaultFailureUrl" value="/login?login_error=t"/>
</bean>
</property>
<property name="authenticationSuccessHandler">
<bean class="LocaleSettingAuthenticationSuccessHandler">
</property>
</bean>
