在 ApplicationController 我添加了：

class ApplicationController < ActionController::Base

# This code never reached when routing error occurs
unless Rails.application.config.consider_all_requests_local
  rescue_from ActionController::RoutingError, with: :render_404
  rescue_from ActionController::UnknownController, with: :render_404
  rescue_from ActionController::UnknownAction, with: :render_404
  rescue_from ActiveRecord::RecordNotFound, with: :render_404
end

当我试图捕获未找到页面的异常时，我注意到当触发路由错误时，上面的代码从未到达，因此，render_404从未调用

Rails.application.config.consider_all_requests_local是假的，有什么想法吗？

这是我得到的：

您应该添加捕获所有路线，如下所示：

match "*path", :to => "application#routing_error"
