如果未登录，则重定向到
LOGIN结果。然后，您应该像这样重写拦截器
public final String intercept(final ActionInvocation invocation) throws Exception { // before save original url Map session = invocation.getInvocationContext().getSession(); Object action = invocation.getAction(); if (!(action instanceof LoginAction)){ String queryString = request.getQueryString(); session.put("savedUrl", request.getRequestURI()+(queryString==null?"":("?"+queryString))); } else { return invocation.invoke(); } if (!processLogin(request, session)) { //return false if not authenticated session.put("isLogin", true); return Action.LOGIN; } else { savedUrl = (String) session.get("savedUrl"); boolean isLogin = (boolean)session.get("isLogin"); if (!StringUtils.isEmpty(savedUrl) && isLogin) { session.put("isLogin", false);return "redirect"; } return invocation.invoke(); }}
