更改HashLocationStrategy的URL路径

Question

最初刷新页面时出现错误404。我通过实现hashlocationstrategy修复了这个问题，但现在当我刷新页面而不是错误404时，它会转到root index.html，这不是我想要的正确位置。相反，我希望它在当前页面上刷新。例如www.site.com/#/form并在刷新时保留在该页面上。可以用angular2中的hashlocationstrategy来完成吗？

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import {router} from './app.router';
import { AppComponent } from './app.component';
import { UsersComponent } from './users/users.component';
import { LocationStrategy, HashLocationStrategy } from '@angular/common';


import { UsercommentsComponent } from './usercomments/usercomments.component';
import { FormComponent } from './form/form.component';



@NgModule({
  declarations: [
    AppComponent,
    UsersComponent,
    UsercommentsComponent,
    FormComponent,

  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    router,
    ReactiveFormsModule
  ],
  providers: [ { provide: LocationStrategy, useClass: HashLocationStrategy }],
  bootstrap: [AppComponent]
})
export class AppModule { }
