如何使用模型初始化angular服务？

export class User {
  id: number;
  name: string;
  email: string;
}

import { Injectable } from '@angular/core';
import { User } from './user.model';

@Injectable({
  providedIn: 'root'
})
export class UserService {
  private initialUser: User = {
    id: 1,
    name: 'John Doe',
    email: 'johndoe@example.com'
  };

  constructor() { }

  // 其他服务方法...
}

import { Injectable } from '@angular/core';
import { User } from './user.model';

@Injectable({
  providedIn: 'root'
})
export class UserService {
  private initialUser: User = {
    id: 1,
    name: 'John Doe',
    email: 'johndoe@example.com'
  };

  constructor() { }

  getInitialUser(): User {
    return this.initialUser;
  }

  // 其他服务方法...
}

import { Component } from '@angular/core';
import { UserService } from './user.service';
import { User } from './user.model';

@Component({
  selector: 'app-user',
  template: `
    <div *ngIf="initialUser">
      <h2>{{ initialUser.name }}</h2>
      <p>Email: {{ initialUser.email }}</p>
    </div>
  `
})
export class UserComponent {
  initialUser: User;

  constructor(private userService: UserService) {
    this.initialUser = this.userService.getInitialUser();
  }
}
