今天在練習springmvc的國際化頁面的時候，遇到了一個問題：
Cannot change HTTP accept header - use a different locale resolution strategy.....
十一月 12, 2018 12:39:42 下午 org.apache.catalina.core.StandardWrapperValve invoke 嚴重: Servlet.service() for servlet [springDispatcherServlet] in context with path [/springMVC_crud] threw exception [Request processing failed; nested exception is java.lang.UnsupportedOperationException: Cannot change HTTP accept header - use a different locale resolution strategy] with root cause java.lang.UnsupportedOperationException: Cannot change HTTP accept header - use a different locale resolution strategy at org.springframework.web.servlet.i18n.AcceptHeaderLocaleResolver.setLocale(AcceptHeaderLocaleResolver.java:47) at org.springframework.web.servlet.i18n.LocaleChangeInterceptor.preHandle(LocaleChangeInterceptor.java:73) at org.springframework.web.servlet.HandlerExecutionChain.applyPreHandle(HandlerExecutionChain.java:130) at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:939) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:876) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:931) at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:822) at javax.servlet.http.HttpServlet.service(HttpServlet.java:622) at org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:807) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:292) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:207) at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:240) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:207) at org.springframework.web.filter.HiddenHttpMethodFilter.doFilterInternal(HiddenHttpMethodFilter.java:77) at org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:108) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:240) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:207) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:212) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:94) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:492) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:141) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:80) at org.apache.catalina.valves.AbstractAccessLogValve.invoke(AbstractAccessLogValve.java:620) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:88) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:502) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1152) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:684) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1539) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.run(NioEndpoint.java:1495) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Unknown Source)
在國內的技術論壇csdn上面找了大半天都沒有解決，後來無意中點進了一個老外的論壇裡面，終於把問題解決了：
如果網站進不了，請看下面：
其中的：Change the bean id from "localResolver"是解決問題的關鍵：其中的localResolver是老外拼錯了，少了一個字母，這不是最重要的，重要的是 to "localeResolver" 。一下是我按照這個修改以後的配置檔案：
<!-- 國際化頁面配置（通過超連結選擇語言那種) 配置SessionLocaleResolver用於將Locale物件儲存於Session中供後續使用(這裡的Id只能用這個：localeResolver，否則會出問題) 第一步： --> <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver"> </bean> <!-- 配置國際化頁面攔截器（通過超連結選擇語言那種）配置LocaleChangeInterceptor 主要用於獲取請求中的locale資訊，將期轉為Locale對像，獲取LocaleResolver物件 第二步： --> <bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"></bean> <!-- 不能直接訪問globle.jsp檔案，要配置對映 ， 第三步--> <mvc:view-controller path="/myGlobal" view-name="global" />
也就是說：第一步當中的bean的id只能是：localeResolver
如果是其他的，大概率都會出錯。那麼，如果你也遇到這樣的問題，請立馬回去檢查你的bean的id吧。
