一网友写的AngularJs按需加载代码，但未验证，放着备用。

 

application.config(

               function($routeProvider) {

                 $routeProvider.

                    when('/:module/:view', {

                        templateUrl: function(params) {

                            return 'app/views/{0}/{1}.jsp'.format(params.module, params.view);

                        }

                   }).

                   otherwise({

                     redirectTo: '/home/landing'

                   });

               });

'use strict';
