angular - 延迟加载 Angular 解析器

Question

有没有办法在加载延迟加载模块之前添加解析器？我尝试添加 resolve到 routs 配置，但它没有被触发，也没有在网上找到任何有用的东西。任何帮助，将不胜感激

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
// services
import {SecondResolverService} from "./second.resolver.service";

const routes: Routes = [
  { path: 'first' , loadChildren: './first/first.module#FirstModule' },
  { path: 'second', loadChildren: './second/second.module#SecondModule' ,resolve : {data : SecondResolverService}}
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

这个配置总是对我有用。
如果这不起作用，则您的解析器可能有问题。

const routes: Routes = [
  {
    path: 'second',
    loadChildren: () => import('/second/second.module')
      .then(m => m.SecondModule),
    resolve: {
      data: SecondResolverService
    }
  },
