javax.faces.application.ViewExpiredException：无法还原视图
我编写了具有容器管理的安全性的简单应用程序。问题是当我登录并打开另一个要注销的页面时，然后回到第一页，然后单击任何链接等或刷新页面，我得到了此异常。我想这是正常的（或者可能不是：）），因为我注销了，会话被破坏了。我应该怎么做才能将用户重定向到例如index.xhtml或login.xhtml并使他免于看到该错误页面/消息？ 换句话说，注销后如何自动将其他页面重定向到索引/登录页面？ 这里是： javax.faces.application.ViewExpiredException: viewId:/index.xhtml - View /index.xhtml could not be restored. at com.sun.faces.lifecycle.RestoreViewPhase.execute(RestoreViewPhase.java:212) at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:101) at com.sun.faces.lifecycle.RestoreViewPhase.doPhase(RestoreViewPhase.java:110) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:118) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:312) at org.apache.catalina.core.StandardWrapper.service(StandardWrapper.java:1523) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:343) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:215) at filter.HttpHttpsFilter.doFilter(HttpHttpsFilter.java:66) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:256) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:215) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:277) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:188) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:641) at com.sun.enterprise.web.WebPipeline.invoke(WebPipeline.java:97) at com.sun.enterprise.web.PESessionLockingStandardPipeline.invoke(PESessionLockingStandardPipeline.java:85) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:185) at org.apache.catalina.connector.CoyoteAdapter.doService(CoyoteAdapter.java:325) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:226) …
