下面两种依赖注入写法等价：
【第一种】
app.controller(‘lrNListingController‘, function (Notifier, Private, timefilter, config) { ?// const Notifier = $injector.get(‘Notifier‘); ?// const Private = $injector.get(‘Private‘); ?// const timefilter = $injector.get(‘timefilter‘); ?// const config = $injector.get(‘config‘); ?//...other codes【第二种】
