$rootScope.$on('$routeChangeError', function(event, current, previous, rejection){

在应用程序的运行块中放置事件跟踪代码通常是一个好主意。这段代码只在应用程序的配置阶段之后运行。
App.run(['$routeParams', '$rootScope', '$location', function($routeParams, $rootScope, $location){
$rootScope.rootPath = "my custom path";
// Event to listen to all the routeChangeErrors raised
// by the resolve in config part of application
$rootScope.$on('$routeChangeError', function(event, current, previous, rejection){
// I am redirecting to rootPath I have set above.
$location.path($rootScope.rootPath);
});
}]);
