今天在练习springmvc的国际化页面的时候，遇到了一个问题：
Cannot change HTTP accept header - use a different locale resolution strategy.....

在国内的技术论坛csdn上面找了大半天都没有解决，后来无意中点进了一个老外的论坛里面，终于把问题解决了：

如果网站进不了，请看下面：
其中的：Change the bean id from "localResolver"是解决问题的关键：其中的localResolver是老外拼错了，少了一个字母，这不是最重要的，重要的是 to "localeResolver" 。一下是我按照这个修改以后的配置文件：
<!-- 国际化页面配置（通过超链接选择语言那种)配置SessionLocaleResolver用于将Locale对象存储于Session中供后续使用(这里的Id只能用这个：localeResolver，否则会出问题) 第一步： --><bean id="localeResolver"class="org.springframework.web.servlet.i18n.SessionLocaleResolver"></bean><!-- 配置国际化页面拦截器（通过超链接选择语言那种）配置LocaleChangeInterceptor 主要用于获取请求中的locale信息，将期转为Locale对像，获取LocaleResolver对象 第二步： --><bean id="localeChangeInterceptor"class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"></bean><!-- 不能直接访问globle.jsp文件，要配置映射 ， 第三步--><mvc:view-controller path="/myGlobal" view-name="global" />修改以后就没有任何问题了。
也就是说：第一步当中的bean的id只能是：localeResolver
如果是其他的，大概率都会出错。那么，如果你也遇到这样的问题，请立马回去检查你的bean的id吧。
