问题
I'm trying to add a new menu item to the default generated JHipster app. I'm using Angular 4 by the way.
The problem I'm facing is that I'm always getting the error below.
Error: Uncaught (in promise): Error: Cannot match any routes. URL Segment: 'user-profile'
The following are the codes I added.
Firstly, I added a folder named user-profile under src/main/webapp/app.
In it, I added index.ts, user-profile.component.html, user-profile.component.ts and user-profile.route.ts
The contents of index.ts
export * from './user-profile.component';
export * from './user-profile.route';
The contents of user-profile.component.ts
import { Component, OnInit } from '@angular/core';
import { Principal } from '../shared';
@Component({
    selector: 'jhi-user-profile',
    templateUrl: './user-profile.component.html'
})
export class UserProfileComponent implements OnInit {
    account: Account;
    constructor(private principal: Principal) {}
    ngOnInit() {
        this.principal.identity().then((account) => {
            this.account = account;
        });
    }
}
The contents of user-profile.route.ts
import { Route } from '@angular/router';
import { UserRouteAccessService } from '../shared';
import { UserProfileComponent } from './';
export const userProfileRoute: Route = {
    path: 'user-profile',
    component: UserProfileComponent,
    data: {
        authorities: [],
        pageTitle: 'user-profile.title'
    }
}; 
The contents of user-profile.component.html
<div>Hello World!</div>
I also modified navbar.html to include a new menu item with the following routerlink
routerLink="user-profile"
Any help to this problem will be greatly appreciated.
Thanks.

You may need to load your router somewhere.
Try perform the following:
- Add a user-profile.module.ts in to the same directory as your user profile component:
 
    import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
    import { RouterModule } from '@angular/router';
    import { UserProfileComponent, userProfileRoute } from './';
    @NgModule({
        imports: [
            RouterModule.forRoot([ userProfileRoute ], { useHash: true })
        ],
        declarations: [
            UserProfileComponent,
        ],
        entryComponents: [
        ],
        providers: [
        ]
    })
    export class UserProfileModule {}
- In the app.module.ts, add the following:
 
    import { UserProfileModule } from './user-profile/user-profile.module';
and
    imports: [
        BrowserModule,
        LayoutRoutingModule,
        ...
        **UserProfileModule**
    ],
Hope it works.
