延迟加载，没有块 - Angular 7

Question

我正在尝试进行延迟加载，并按照角度的official docs中的步骤进行操作。问题是没有显示的块。

有没有我忘记造成这种情况的步骤？

应用路由

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';

const routes: Routes = [
  {
    path: 'prospect',
    loadChildren: './prospect/prospect.module#ProspectModule'
  },
  {
    path: 'customer',
    loadChildren: './customer/customer.module#CustomerModule'
  },
  {
    path: '',
    redirectTo: '',
    pathMatch: 'full'
  }
  // { path: '**', redirectTo: '/error-404' }
];

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

前景路由

import { NgModule } from '@angular/core';

import { ProspectComponent } from './prospect.component';

import { RouterModule, Routes } from '@angular/router';

const routes: Routes = [
  {
    path: '',
    component: ProspectComponent
  },
  {
    path: '',
    redirectTo: '',
    pathMatch: 'full'
  }
];

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

前景模块

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

import { CustomerRoutingModule } from './customer-routing.module';

import { CustomerComponent } from './customer.component';



@NgModule({
  imports: [
    CommonModule,
    CustomerRoutingModule
  ],
  declarations: [CustomerComponent],
})
export class CustomerModule { }

客户路由

import { NgModule } from '@angular/core';

import { CustomerComponent } from './customer.component';

import { RouterModule, Routes } from '@angular/router';

const routes: Routes = [
  {
    path: '',
    component: CustomerComponent
  },
  {
    path: '',
    redirectTo: '',
    pathMatch: 'full'
  }
];

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

客户模块

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

import { ProspectRoutingModule } from './prospect-routing.module';

import { ProspectComponent } from './prospect.component';

@NgModule({
  imports: [
    CommonModule,
    ProspectRoutingModule
  ],
  declarations: [ProspectComponent]
})
export class ProspectModule { }

我注意到它在我服务时会产生大块。

我是否正确实现了Lazy加载？

Answer 1

你在你的应用程序中使用延迟加载模块的服务吗？如果您不使用共享模块，则可以中断延迟加载。

Answer 2

我改变你的应用程序路由的路由常量，请这...

const routes: Routes = [    
{
  path: '',
  redirectTo: 'prospect',
  pathMatch: 'full'
},
{
   path: 'prospect',
   loadChildren: './prospect/prospect.module#ProspectModule'
},
{
   path: 'customer',
   loadChildren: './customer/customer.module#CustomerModule'
},
// { path: '**', redirectTo: '/error-404' }
];
