角子级路由在懒加载模块内的问题

Question

我有角度路由器的问题。我在这里延迟加载了一个组件，它有自己的路由和子路由。我的问题在于使用路由器出口访问这些路由。

app-routing.module.ts

  {
    path: 'sign-in',
    component: SignInComponent
  },
  {
    path: 'module',
    component: MainPageComponent,
    canActivate: [AuthGuard],
    children: [
      {
        path: 'students-badges',
        canLoad: [LoadBadgeGuard],
        loadChildren: './views/badge/badge.module#BadgeModule'
      },
      {
        path: 'attendance',
        component: ProfessorNLecturesComponent,
        children: [
          {
            path: ':tGroupId',
            component: PresentListComponent
          }
        ]
      },
      {
        path: 'didactic-agenda',
        component: DidacticCourseComponent,
        children: [
          {
            path: ':didacticCourseId',
            component: DidacticCourseDetailsComponent
          }
        ]
      },
      {
        path: 'admission-backOffice',
        loadChildren: './views/admission/admission.module#AdmissionModule',
      },
      {
        path: 'online-exam',
        loadChildren: './views/online-exam/online-exam.module#OnlineExamModule'
      },
      {
        path: 'questionnaire',
        component: LandingViewComponent
      }
    ]
  },
  {
    path: '',
    redirectTo: '/module',
    pathMatch: 'full'
  },
  {
    path: '**',
    redirectTo: '/module',
    pathMatch: 'full'
  }
];

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

  {
    path: '',
    component: ExamsComponent,
    children: [
      {
        path: ':examId/:configId',
        component: ExamComponent
      }
    ]
  }
];

@NgModule({
  imports: [
    RouterModule.forChild(ONLINE_EXAM_ROUTES)

})
export class OnlineExamRoutingModule {}

  <mat-sidenav-content>

      </div>

      <div class="footer-row">
        <mat-paginator [showFirstLastButtons]="true"
                       [length]="listMetadata.totalRecords"
                       [pageSize]="listMetadata.pageSize"
                       [pageSizeOptions]="[5, 15, 45]"
                       (page)="paginator($event)"></mat-paginator>
      </div>
    </div>
  </mat-sidenav-content>

  <mat-drawer style="width: 100%"
              #studentExamConfig
              position="end"
              mode="over">

    <div class="fluid-container panel-header">
      <div class="row">
        <div class="col panel-title">{{label}}</div>
        <div class="col"></div>
      </div>
    </div>

    <router-outlet></router-outlet>
  </mat-drawer>
</mat-sidenav-container>

我希望子路由的渲染会在router-outlet标签内进行， 但是它将我重定向到主路由器“ /模块”中。
