以下是一个使用Angular 2+从服务器加载组件的解决方法的代码示例：

1. 创建一个组件服务

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable()
export class ComponentLoaderService {
  constructor(private http: HttpClient) {}

  loadComponent(url: string): Observable {
    return this.http.get(url);
  }
}

2. 创建一个动态加载组件的指令

import { Directive, ViewContainerRef } from '@angular/core';

@Directive({
  selector: '[componentLoader]'
})
export class ComponentLoaderDirective {
  constructor(public viewContainerRef: ViewContainerRef) { }
}

3. 在需要加载组件的地方使用指令和服务

import { Component, ViewChild, ViewContainerRef } from '@angular/core';
import { ComponentLoaderDirective } from './component-loader.directive';
import { ComponentLoaderService } from './component-loader.service';

@Component({
  selector: 'app-root',
  template: `
    

      
    
  `,
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  @ViewChild(ComponentLoaderDirective, {static: true}) componentLoader: ComponentLoaderDirective;

  constructor(
    private componentLoaderService: ComponentLoaderService,
    private viewContainerRef: ViewContainerRef
  ) {}

  ngOnInit() {
    const componentUrl = 'http://example.com/my-component.js';
    this.componentLoaderService.loadComponent(componentUrl).subscribe((component) => {
      this.loadComponent(component.default);
    });
  }

  loadComponent(component: any) {
    const componentFactory = this.viewContainerRef.createComponent(component);
    // 可以通过componentFactory.instance访问加载的组件实例
  }
}

4. 在Angular模块中提供服务和指令

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpClientModule } from '@angular/common/http';

import { AppComponent } from './app.component';
import { ComponentLoaderDirective } from './component-loader.directive';
import { ComponentLoaderService } from './component-loader.service';

@NgModule({
  imports: [BrowserModule, HttpClientModule],
  declarations: [AppComponent, ComponentLoaderDirective],
  providers: [ComponentLoaderService],
  bootstrap: [AppComponent]
})
export class AppModule { }

以上代码示例展示了如何使用Angular 2+从服务器加载组件。使用ComponentLoaderService服务加载组件代码库，并通过ComponentLoaderDirective在模板中创建一个容器来动态加载组件。在AppComponent中，我们使用ViewChild装饰器获取到ComponentLoaderDirective实例，并通过ComponentLoaderService加载组件。在loadComponent方法中，我们使用ViewContainerRef.createComponent方法将组件添加到容器中。
