按需加载所需文件

bower install oclazyload --save

<script src="bower_components/oclazyload/dist/ocLazyLoad.min.js"></script>

依赖注入oc.lazyLoad

路由resolve配置：

resolve: {
                loadPlugin: function ($ocLazyLoad) {
                    return $ocLazyLoad.load([
                        {
                            serie: true,
                            name: 'ngFileUpload',(按需加载模块名称)
                            files: ['bower_components/ng-file-upload/ng-file-upload-shim.js','bower_components/ng-file-upload/ng-file-upload.js','content/ui-select.css','bower_components/angular-ui-select/dist/select.js','app/main/accountManage/commitUserAudit.service.js','app/main/accountManage/fullUserinfo.controller.js']
                        }
                    ]);
                }
}
