How can have multiple Modules without repeat injections

问题

I have 2 applications app1 & app2

app1.js

var app = angular.module("app1", ["ngRoute"]);

app.config(['$routeProvider', function ($routeProvider) {
   $routeProvider.when('/view3', {
    templateUrl: 'http://localhost:40/partials/partial3.html',
    controller: 'MyCtrl1 as self'
   });

   $routeProvider.otherwise({
    redirectTo: '/view3'
   });
}]);

app1 has ngRoute module, and route config

app2.js

var app = angular.module("app2", ["app1"]);

app2 has app1 module

---

Note: app1 run in localhost:40 & app2 in localhost:50.

Question is: How can use app1 route configs without inject ngRoute in app2?

i run app2 with requirejs & it works if i inject ngRoute in app2.
