如何使用material2工具栏,按钮和angular-cli路由器

html的

<nav>
  <md-toolbar color = "primary">
    <a [routerLink] = "['new-patient']">New Patient</a>

    <button md-icon-button
            color = "accent">
      <md-icon class = "material-icons md-24">person_add</md-icon>
    </button>
  </md-toolbar>
</nav>

.TS

import { Component,OnInit } from '@angular/core';
import { ROUTER_DIRECTIVES,ROUTER_PROVIDERS } from '@angular/router';
import { MdToolbar } from '@angular2-material/toolbar';
import { MdIcon,MdIconRegistry } from '@angular2-material/icon';
import { MdButton } from '@angular2-material/button';

@Component({
  moduleId: module.id,selector: 'epimss-toolbar',templateUrl: 'toolbar.component.html',styleUrls: ['toolbar.component.css'],providers: [MdIconRegistry],directives: [MdButton,MdIcon,MdToolbar,ROUTER_DIRECTIVES],})
export class ToolbarComponent implements OnInit {

  constructor() {}

  ngOnInit() {
  }
}

我的路由器实际上使用上面的代码.

但是,我正在尝试

<a [routerLink] = "['new-patient']">New Patient</a>

是一个被激活的路线

<button md-icon-button
        color = "accent">
  <md-icon class = "material-icons md-24">person_add</md-icon>
</button>

点击.

我尝试了以下但它不起作用.

<button md-icon-button
        color = "accent"
        [routerLink] = "['new-patient']">
  <md-icon class = "material-icons md-24">person_add</md-icon>
</button>

感谢您给予的任何帮助,谢谢.
