两个不同路由的控制器可以共享相同的服务吗？

// 创建一个共享服务
@Injectable()
export class SharedService {
  sharedData: any;

  constructor() {
    this.sharedData = 'Shared data';
  }

  getSharedData() {
    return this.sharedData;
  }
}

// 控制器1
@Component({
  selector: 'controller1',
  template: `
    <div>{{ sharedData }}</div>
  `,
})
export class Controller1 {
  sharedData: any;

  constructor(private sharedService: SharedService) {
    this.sharedData = sharedService.getSharedData();
  }
}

// 控制器2
@Component({
  selector: 'controller2',
  template: `
    <div>{{ sharedData }}</div>
  `,
})
export class Controller2 {
  sharedData: any;

  constructor(private sharedService: SharedService) {
    this.sharedData = sharedService.getSharedData();
  }
}
