Spring security实现国际化问题

Posted 2021-01-04 boboxing2017

这两天Spring用户登录国际化这个问题困扰我好久啊，于昨天晚上终于把它干掉了。

场景就是我们公司的产品-incopat，需要支持中英文，用户登录这块用的spring自带的security，需求讲的通俗一点就是，中文版提示中文提示信息，英文版提示英文版信息，废话不多说，见代码。

首先配置文件

security-config.xml

 1 <beans:bean id="customUsernamePasswordAuthenticationFilter"
 2         class="com.incoshare.base.security.CustomUsernamePasswordAuthenticationFilter"
 3         p:authenticationManager-ref="authenticationManager"
 4         p:filterProcessesUrl="/doLogin" p:sessionAuthenticationStrategy-ref="compositeSessionAuthenticationStrategy"
 5         p:authenticationSuccessHandler-ref="authenticationSuccessHandler"
 6         p:authenticationFailureHandler-ref="authenticationFailureHandler"
 7         p:rememberMeServices-ref="rememberMeServices"
 8         p:authenticationDetailsSource-ref="customWebAuthenticationDetailsSource">
 9 </beans:bean>
10 
11 
12 <beans:bean id="messageSource"
13         class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
14         <beans:property name="basename"
15             value="classpath:messages/security/messages" />
16 </beans:bean>

配置文件只贴了关键部分，第一个bean 配置登录的过滤器，第二个bean加载messages文件（这里有需要注意的地方如果想引用自己的message文件，建好文件后提供相对地址就可以了，classpath必须要哦！文件命名也是有规则的，message_en  就是下划线带上语言简称，这个简称需要跟网站上切换中英文标示一致），配置文件就这些

下面贴上过滤器代码

144                 username = RegexUtil.getRealIp(request);
145                 password="";
146                 authRequest = new IpUserAuthenticationToken(username,password);

152             setDetails(request, authRequest);
153 
154             return this.getAuthenticationManager().authenticate(authRequest);
155         }
156 }

这块先声明下，代码不是我写的，看着很乱很糟糕吧。主要上边标黄的两个地方就可以了。

值设置后会通过this.getAuthenticationManager().authenticate(authRequest) 去初始化，喜欢研究源码的朋友看一跟一下看看

org.springframework.context.i18n.LocaleContextHolder这个类

1 public static LocaleContext getLocaleContext() {
2         LocaleContext localeContext = localeContextHolder.get();
3         if (localeContext == null) {
4             localeContext = inheritableLocaleContextHolder.get();//这里会把你设置的值放到Spring 容器
5         }
6         return localeContext;
7 }

好了，关键的地方都说完了，这几天搞了这么久，写完了也没多少东西，代码就是这么美妙，解决问题的过程是漫长苦恼的，但最终解决有可能就一两行代码的事。

关于这一块有问题的可以随时沟通。
