我将动态地将组件与服务中的另一个组件进行比较，首先，在服务工厂中同时对两个组件进行创建，然后创建可以访问ViewContainer的组件。但是无法创建组件！

服务内容：

@Injectable({
    providedIn: 'root'
})
export class ModalService {

    componentRef: ComponentRef;

    constructor(private _modalService: BsModalService,
                private resolver: ComponentFactoryResolver,
                private injector: Injector) {
    }

    open(componentType: any) {

        const cOntentFactory= this.resolver
            .resolveComponentFactory(componentType);

        const templateFactory = this.resolver
            .resolveComponentFactory(ModalTemplateComponent);

        const compOnentRef= templateFactory.create(this.injector);
        componentRef.instance.container.createComponent(contentFactory);

this._modalService.show(componentRef.componentType, {class: 'modal-lg', initialState: {data: {test:true}});

    }
}

零件 ：

    selector: 'lib-modal-template',
    template: `
        
{{title}}
        
        
    `,
    styleUrls: ['./modal-template.component.css']
})
export class ModalTemplateComponent implements OnInit {

        title:string;
    @ViewChild('container', {read: ViewContainerRef, static: true}) container: ViewContainerRef;
}

例如：

this._modalService.open(NewUserForm,...);
